Package Max

pattrstorage

Save and recall pattr presets

Description

View and modify client object data, and store or recall presets.

Discussion

Through the pattrstorage object, you can get/set any pattrstorage or autopattr data (a la pattrhub, although you can talk to any object exposed to pattr or autopattr, not just those in the same patch). Data may be recalled as an interpolated value between 2 stored values.

Arguments

name[symbol]
optional

A symbol argument may be optionally used to set the pattrstorage object's scripting name. In the absence of an argument, the pattrstorage object is given an arbitrary, semi-random name, such as u197000004.

Attributes

activewritemode[int]

Sets the write mode for the active property of client objects. The default is 0 (disabled). When enabled, the active state of client objects will be saved with the XML preset data file and restored when this file is re-read.

autopattr_vis[int]

Sets the visibility of autopattr objects in the clientwindow and storagewindow displays. The default is 0 (disabled). Since autopattr objects are not used for forming path names, one can generally ignore them for the purposes of display. When performing pattrstorage object functions, such as setting the active state or priority for an entire set of objects being exposed by a single autopattr object, the user needs to know the name of the objects' actual container object. Enabling autopattr_vis may make this process somewhat clearer visually and conceptually.

autorestore[int]

Enables or disables the pattrstorage object's autorestore state. The default is 1 (on). When enabled, the pattrstorage object will automatically try to locate and read an XML file representing preset data when the patcher loads. The pattrstorage object will attempt to load the last-saved file. If the pattrstorage object in question has never saved a file, the object will attempt to load a file with the name (name).xml, where (name) is the patcher name of the pattrstorage object (usually, its argument).

autowatch[int]

Sets the pattrstorage object's file watching behavior. The default is 0 (disabled). When file watching is enabled, the most recently read or written XML data file will be reloaded automatically if it is modified. This allows you to use an external editor for your XML data file. When you save the file, the pattrstorage object will notice. Note that when the file is re-read, any currently unsaved data will be lost.

backupmode[int]

Sets the number of backup XML files to be maintained and rotated by the pattrstorage object when writing files. The default is 0 (disabled). The argument specifies the number of backups the pattrstorage object should make before the files start rotating (being automatically deleted to make room for new backups). The most recent backup is called pstoname.bak.xml. The next, pstoname_1.bak.xml, followed by pstoname_2.bak.xml, etc.

changemode[int]

Sets the pattrstorage object's data-filtration behavior. The default is 0 (disabled). When enabled, only changed values are sent from the pattrstorage object to client objects, and repeated data is filtered.

client_rect[4 floats]: 50. 50. 400. 500.

Sets a new size and position for the client list window. The window position is specified in global coordinates by 4 numbers (left, top, right, bottom).

dirty[int]

Enables or disables the patcher-dirty flag. The default is 0 (disabled). When enabled, the pattrstorage object will dirty the patch whenever its state changes.

fileusagemode[int]

Enables or disables the inclusion of JSON/XML storage files in collectives and standalones. The default is 0 (include storage file).

flat[int]

Enables or disables the pattrstorage object's client list display flag. The default is 0 (disabled). When enabled, the pattrstorage object's 2 windows will not display a hierarchical view of clients, instead display only data-containing objects (no patchers), and their full path name or alias.

greedy[int]

Sets the pattrstorage object's client search behavior flag. The greedy attribute provides a way to limit the amount of data a single pattrstorage object will manage. The following values are possible:

0 = disabled (the default). The pattrstorage object can see all pattr objects or objects bound to autopattr objects in any child patches of the pattrstorage object (or child patches of those child patches, tunneling down through the patcher hierarchy), until another pattrstorage object is found. Although the pattrstorage object found in a child patch will be a client of the parent pattrstorage object, no other objects at that level or below in the patcher hierarchy will be.

1 = see everything. When the greedy attribute is set to 1, the pattrstorage object can see everything, all the way down to the bottom of the patcher hierarchy (including any pattrstorage objects it finds along the way).

2 = clients only. When the greedy attribute is set to 2, the pattrstorage object can only see potential client objects in its patch. No other patches are searched.

notifymode[int]

Sets the pattrstorage object's add/remove-notification behavior. The default is 0 (disabled). When enabled, the pattrstorage object will send a message from it's outlet every time an object is added or removed from its client list, in the form [add/remove] [object pathname] . Note that the pattrstorage object must occasionally purge and fully rebuild its client list in response to certain events, resulting in significant output when notifymode is enabled and objects are being added and removed regularly.

outputmode[int]

Sets the pattrstorage object's auto-output behavior. The default is 0 (disabled). When enabled, the pattrstorage object will send a message from its outlet every time a value is sent to one of its client objects, in the form [object pathname] [data ...] . The following modes are available:

0 = disabled
1 = output all values sent to client objects
2 = output only changed values sent to client objects (see changemode)
3 = output all values sent to client objects not initiated by a message to the pattrstorage object
4 = output only changed values sent to client objects not initiated by a message to the pattrstorage object (see changemode)
5 = output all values sent to client objects not initiated by a message to any pattr-system object (pattr, pattrhub, pattrforward, pattrstorage).
6 = output only changed values sent to client objects not initiated by a message to any pattr-system object (see changemode)

parameter_enable[int]

Enables use of this object with Max for Live Parameters and setting initial parameter values in Max..

savemode[int]

Sets the pattrstorage object's save behavior. The default is 1 (prompt on object free). In this mode, if the pattrstorage object's preset data has changed (presets have been stored, deleted or modified since the last file read or write operation) at the time the object is freed, the object will prompt the user to write a preset file. In mode 2, pattrstorage will attempt to autosave a preset file (without user interaction), whenever the patcher is saved. In mode 0, pattrstorage will neither prompt nor autosave. In mode 3, pattrstorage will attempt to autosave a preset file (without user interaction), whenever the patcher is freed.

The following values are possible:

0 = Neither prompt nor autosave
1 = Prompt the user to save a preset file when the object is freed (default)
2 = Attempt to autosave whenever the patcher is saved, or if unsuccessful, prompt the user to save a preset file
3 = Attempt to autosave (without user interaction) when the patcher is freed. Failing that, prompt the user

storage_rect[4 floats]: 600. 50. 400. 500.

Sets a new size and position for the stored data window. The window position is specified in global coordinates by 4 numbers (left, top, right, bottom).

subscribemode[int]

Sets the subscription mode. The default is 0 (disabled). When enabled, the pattrstorage object uses a user-specified subscription list to determine which objects are clients, rather than discovering and maintaining all objects within the patcher/patcher hierarchy (as determined by the greedy attribute. The subscribe and unsubscribe messages can be used to add and remove objects to and from this list, and the getsubscriptionlist message can be used to output a list of currently subscribed objects.

Common Box Attributes

Below is a list of attributes shared by all objects. If you want to change one of these attributes for an object based on the object box, you need to place the word sendbox in front of the attribute name, or use the object's Inspector.

Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.

Parameter Attributes

Orderint

Sets the order of recall of this parameter. Lower numbers are recalled first. The order of recall of parameters with the same order number is undefined.

Parameter Mode Enableint

Parameter Mode Enable (not available from Parameters window)

Link to Scripting Nameint

When checked, the Scripting Name is linked to the Long Name attribute.

Long Namesymbol

The long name of the parameter. This name must be unique per patcher hierarchy.

Short Namesymbol

Sets the short name for the object's visual display. The maximum length varies according to letter width, but is generally in a range of 5 to 7 characters.

Typeint

Specifies the data type. The data types used in Max for Live are:

Float
Int
Enum (enumerated list)
Blob

Note: By convention, the Live application uses floating point numbers for its calculations; the native integer representation is limited to 256 values, with a default range of 0-255 (similar to the char data type used in Jitter). When working with Live UI objects whose integer values will exceed this range, the Type attribute should be set to Float, and the Unit Style attribute should be set to Int.

Range/Enumlist

When used with an integer or floating point data type, this field is used to specify the minimum and maximum values of the parameter.
When used with an enumerated list (Enum) data type, this field contains a space-delimited list of the enumerated values (if list items contain a space or special characters, the name should be enclosed in double quotes).

Clip Modulation Modeint

Sets the Clip Modulation Mode used by the Live application. The modulation modes are:

None
Unipolar
Bipolar
Additive
Absolute

Clip Modulation Rangelist

This parameter is only used with the Absolute modulation mode. It specifies defines the range of values used.

Initial Enableint

When checked (set to 1), the UI object can store an initialization value. The value is set using the Initial attribute (see below).

Initiallist

Sets the initial value to be stored and used when the Initial Enable attribute is checked.

Unit Styleint

Sets the unit style to be used when displaying values. The unit style values are: Int: displays integer values
Float: displays floating point values
Time: displays time values in milliseconds (ms)
Hertz: displays frequency values (Hz/kHz).
deciBel: displays loudness (dB)
%: Percentage
Pan: displays Left and Right values
Semitones: displays steps (st)
MIDI: displays pitch corresponding to the MIDI note number
Custom: displays custom data type
Native: defaults to floating point values

Custom Unitssymbol

Sets the units to be used with the 'Custom' unit style (see "Unit Style", above). Custom unit strings may be simple symbols (e.g. "Harmonic(s)"), in which case the parameter's value will be displayed in its 'Native' display mode, followed by the symbol (e.g. "12 Harmonic(s)" for an Int-typed parameter or "12.54 Harmonic(s)" for a Float-typed parameter). For additional control over the numerical component displayed, a sprintf-style string may be used (e.g. "%0.2f Bogon(s)", which would display a value such as ".87 Bogons").

Exponentfloat

When set to a value other than 1., the parameter's input and output values will be exponentially scaled according to the factor entered in this column.

Stepsint

The number of steps available between the minimum and maximum values of a parameter. For instance, if the parameter has a range from 0.-64., with Steps set to 4, the user can only set the parameter to 0, 21.33, 42.66 and 64.

Parameter Visibilityint

For automatable parameters (Int, Float, Enum), 'Stored Only' disables automation, although parameter values are stored in presets. 'Hidden' causes the parameter's value to be ignored when storing and recalling data. Non-automatable parameters (Blob) are 'Stored Only' by default, and can be set to 'Hidden', if desired.

Update Limit (ms)int

Speed limits values triggered by automation.

Defer Automation Outputint

Defers values triggered by automation.

Messages

int

Recalls the data from the preset specified by int .

Arguments:
  • index [int]

float

Recalls the data from the preset specified by float . If the number falls between two whole numbers (e.g. 1.5 ), the pattrstorage object will interpolate between the data stored in the preset corresponding to the integer portion of the float and the data stored at the preset numbered one higher (e.g. 1.5 will cause pattrstorage to interpolate 50% between presets 1 and 2). See the interp message for more information about interpolation modes.

Arguments:
  • index [float]

anything

Incoming messages to the pattrstorage object are analyzed. If the first element of the message matches the path name or alias of an object maintained by the pattrstorage object (visible in the object's client list), the subsequent arguments in the message set that object's value. Otherwise, the message is ignored.

Arguments:
  • arguments [list]

active

The word active , followed by a symbol that specifies the path name or alias of a client object and a 1 or 0, sets that object's active status. When a client object is active (default), its data will be recalled when presets are recalled--otherwise, the object is ignored during recall. Setting the active state of a parent object (such as a patcher-any client object containing other client objects), automatically sets the active state of the child objects of the parent to the same value.

Arguments:
  • client [list]

alias

The word alias , followed by two symbols, generates an alias for the client object whose path name is given in the first argument. The alias permits the object to be referred to by a name given in the second argument.

For example, alias a_patcher::a_pattr the_pattr would alias the object at the location a_patcher::a_pattr to the name the_pattr.

Aliases can be used interchangeably with path names within the pattrstorage object, and are useful for referring to long paths by simpler, shorter names.

get alias The word get alias , followed by a symbol that specifies the path name of a client object, returns that object's alias (if any) from the pattrstorage object's outlet, preceded by the symbol alias .

Arguments:
  • client [symbol]
  • alias [symbol]

clear

The word clear removes all presets from the pattrstorage object's internal list.

client_close

Closes the client list window.

clientwindow

Opens the pattrstorage object's client list window (the title bar reads clientwindow (name), where (name) is the patcher name of the pattrstorage object which created the window).

Arguments:
  • name [list]

copy

The word copy , followed by 2 or 3 arguments, copies the stored values from one numbered preset to another. Followed by 2 numbers, the stored values from the preset slot specified by the first number will be copied to the preset slot specified by the second number. If that slot doesn't yet exist, it will be automatically created. Followed by a symbol and 2 numbers, the stored values from a preset slot, as specified by the first number, of the pattrstorage object referred to by the symbol will be copied to a preset slot, as specified by the second number, of the object receiving the copy message. For example, the message copy parent::psto_parent 3 1 would cause preset 3 of the pattrstorage object called psto_parent, located in the parent patch of the pattrstorage object receiving the copy message, to be copied to preset 1 of the pattrstorage object receiving the message. In order for this to function reliably, client path names must match exactly. If they do not, the data for that client is ignored.

Arguments:
  • pattrstorage [symbol]
  • from-index [int]
  • t0-index [int]

(mouse)

Double-clicking on a pattrstorage object opens the object's client list window, as if the object had received the clientwindow message.

delete

The word delete , followed by a number, clears any data in the preset whose index is specified by that number and removes the preset from the pattrstorage object's internal list. If delete is not followed by an argument, all presets are cleared and removed. See the getslotlist message for further information on viewing the object's list of presets.

Arguments:
  • index [list]

dump

The word dump reports the current value of all client objects from the pattrstorage object's outlet as a series of messages, each in the form [object pathname] [data ...] . The output of dump is finished when the message dump done is output.

fade

Identical to the recall message. Deprecated.

Arguments:
  • list [list]

fillempty

The word fillempty sets the value of any empty preset slots for all client objects to the current value of the respective object. For client pattr objects with an initial value, the initial value will be used instead. No data is sent to the client objects themselves.

getactive

The word getactive , followed by a symbol that specifies the path name or alias of a client object, reports the active status of the client object from the pattrstorage object's outlet, preceded by the symbol active .

Arguments:
  • client [list]

getalias

The word getalias , followed by a symbol that specifies the path name or alias of a client object, will cause pattrstorage to return that client-object's alias from its outlet.

Arguments:
  • client [list]

getclientlist

The word getclientlist reports the path names of any client objects from the pattrstorage object's outlet as a series of messages, each preceded by the symbol clientlist . The output of getclientlist is finished when the message clientlist done is output.

getcurrent

The word getcurrent reports the currently active preset from the pattrstorage object's outlet, preceded by the symbol current .

getedited

The word getedited reports the edit state of the currently active preset from the pattrstorage object's outlet, preceded by the symbol edited . If the data in the currently active preset has been edited, the state is reported as 1 . Otherwise, the edit state is reported as 0 .

getinterp

The word getinterp , followed by a symbol that specifies the path name or alias of a client object, reports that object's interpolation mode from the pattrstorage object's outlet, preceded by the symbol interp .

Arguments:
  • client [list]

getlockedslots

The word getlockedslots reports the indices of any locked slots from the pattrstorage object's outlet as a list, preceded by the symbol lockedslots .

getpriority

The word getpriority , followed by a symbol that specifies the path name or alias of a client object, reports that object's priority from the pattrstorage object's outlet, preceded by the symbol priority .

Arguments:
  • client [list]

getslotlist

The word getslotlist reports the numbers of any valid presets from the pattrstorage object's outlet, preceded by the symbol slotlist .

getslotname

The word getslotname , followed by a number, causes the name of the preset slot specified by the number to be output from the pattrstorage object's outlet, preceded by the symbol slotname .

Arguments:
  • index [int]

getslotnamelist

The word getslotnamelist , followed by an optional number, reports the slot names of all used slots to be sent from the pattrstorage object's outlet as a series of messages, each preceded by the symbol slotlist . The output of getslotlist is finished when the message slotname done is output.

Without an argument, or with an argument of 0, the getslotnamelist message will cause all slots from 0 to the largest stored slot number to be output, regardless of whether the slot has been defined or not. The facilitates the use of the getslotlist message with objects such as umenu. To filter undefined slots (even if they have names), send the getslotlist message with a non-0 argument.

For more information, see the pattrstorage object's help file.

Arguments:
  • range [int]

getstoredvalue

The word getstoredvalue , followed by a symbol that specifies the path name or alias of a client object and a number which specifies a preset, reports that object's value, as stored in that preset slot, from the pattrstorage object's outlet, in the form [object pathname or alias] [data ...] .

Arguments:
  • client [list]

getsubscriptionlist

The word getsubscriptionlist causes the names of all subscribed objects to be sent from the pattrstorage object's outlet as a series of messages, each preceded by the symbol subscriptionlist . The output of getsubscriptionlist is finished when the message subscriptionlist done is output. See the subscribemode attribute for more information.

grab

The word grab causes the current value of all client objects to be reacquired by the pattrstorage object. This is particularly useful when the pattrstorage object is managing client objects whose data changes internally, without sending notifications to the pattr system.

insert

The word insert , followed by a number, stores the data for every object maintained by pattrstorage in a numbered preset. The number argument specifies the index of the preset to be stored. Any presets numbers at the specified index or higher are automatically incremented to make room for the inserted preset.

Arguments:
  • index [int]

interp

The word interp , followed by at least 1 and up to 3 arguments ( symbol , symbol , float/symbol ), sets the interpolation status and mode for a specific client object. The first symbol specifies the path name or alias of a client object. The second symbol argument determines the mode, and can be one of the following values:

off - No interpolation. Same as no additional argument.

linear - Linear interpolation. Presets recalled using float or fade messages will be interpolated using a standard linear algorithm.

thresh - Threshold. Takes optional 3rd argument, which sets the threshold. Presets recalled using float or fade messages will recall data from the first preset specified when the fade amount is below the threshold, and will recall data from the second preset specified when the fade amount is greater than or equal to the threshold.

ithresh - Inverse threshold. Takes optional 3rd argument ( float ), which sets the threshold. Presets recalled using float or fade messages will recall data from the first preset specified when the fade amount is greater than or equal to the threshold, and will recall data from the second preset specified when the fade amount is less than the threshold.

pow - Power curve. Takes optional 3rd argument ( float ), which sets the exponent to which the fade amount will be raised. Presets recalled using float or fade messages will recall data between the two specified presets, along the curve described. Power curves can be used to create faster or slower "attacks" and "decays" for the fade envelope.

table - Table-specified curve. Takes optional 3rd argument ( symbol ), which specifies the name of a table to use for curve lookup. Presets recalled using float or fade messages will recall data between the two specified presets, along the curve described in the table. Tables are assumed to contain values between 0 and 100, representing the new fade amount * 100 (this is clipped internal to the pattrstorage object, but is not normalized). The length of the table is stretched to match the expected fade values (between 0 and 1), so any number of table entries can be used. If the lookup fade amount does not fall exactly onto a table-specified value, linear interpolation is used to determine the new fade amount. Please see the pattrstorage help file for examples of table-specified interpolation.

Arguments:
  • arguments [list]

locate

The word locate , followed by a symbol corresponding to the path name or alias of an object, will cause the containing patcher of that object to be opened.

Arguments:
  • client [symbol]

lock

The word lock , followed by 2 numbers, sets the lock status for a particular preset number. The first argument specifies the preset number to be locked or unlocked. The second argument specifies the lock state, and should be either 0 (unlocked) or 1 (locked). Locked presets cannot be deleted (using the delete or remove messages) or overwritten (using the store message). Locked presets can be moved (as a result of insert , remove or renumber messages, if performed on other presets). Locks are saved in the preset data file.

Arguments:
  • index [int]
  • status [int]

lockall

The word lockall , followed by a number, sets the lock status for all presets at once. The argument specifies the lock state, and should be either 0 (unlocked) or 1 (locked). Locked presets cannot be deleted (using the delete or remove messages) or overwritten (using the store message). Locked presets can be moved (as a result of insert , remove or renumber messages, if performed on other, unlocked presets). Locks are saved in the preset data file.

Arguments:
  • status [int]

priority

The word priority , followed by a symbol that specifies the path name or alias of a client object and a number, sets the recall and display priority for that object. When presets are recalled, the data for client objects will be restored in the order established by priority . Lower priorities are executed first. Negative priorities are permitted. Priority is only respected within a single level of the patcher hierarchy. Data in parent patchers will always be restored before data in nested patchers.

Arguments:
  • client [list]

purge

The word purge rebuilds the internal client list of the pattrstorage object, removing entries for client objects which have been deleted or moved. Typically, the pattrstorage object retains a reference to such objects, so that their settings ( priority , active , interp , etc.) can be restored if the objects reappear.

read

The word read , followed by an optional symbol that specifies a filename, reads an JSON or XML file representing preset data from disk into the pattrstorage object. If the argument is given, and represents a valid file path, the file will be read from that location--otherwise, a standard File Dialog will be presented for the user to manually choose the file to be read.

Arguments:
  • filename [list]

readagain

The word readagain re-reads an JSON or XML file previously specified by the read or write messages. If no file has been previously specified, a standard File Dialog will be presented for the user to manually choose the file to be read.

Arguments:
  • filename [list]

recall

The word recall , followed by 1 to 4 arguments, recalls data from a preset. If recall is followed by a number or a floating-point number, the data for every object whose value is stored in the specified preset (or in the interpolated preset represented by a floating-point number - see the float message) will be recalled. If recall is followed by 2 arguments--a symbol and a number--and the symbol argument matches the path name or alias of a client object, only the data for the specified object will be recalled. The number argument always specifies the index (or interpolated index) of the preset to recall.

Followed by 3 or 4 arguments, the recall message recalls interpolated data from 2 presets at a specified weight between the two. If the word recall is followed by two numbers that specify the indices of two presets and a a floating point number between 0 and 1.0 that specifies an interpolation value, the data for every object whose value is stored in the specified presets will be recalled.

If recall is followed by a symbol that specifies the path name or alias of a client object followed by two numbers that specify the indices of two presets and a floating point interpolation value, only the data for the specified object will be recalled.

In these latter cases, the floating point argument specifies the weight of the interpolation, and should be between 0. and 1. A floating point argument of 0. would simply recall the data for the preset matching the first index, and 1. would recall the data for the preset matching the second index. See the interp message for more information about interpolation modes.

Arguments:
  • client-name, preset-indices, and interpolation-value [list]

recallmulti

The word recallmulti , followed by at least 2 numeric arguments, permits weighted recall of multiple presets. Each argument determines the (normalized) weight of a particular preset in the final output. If the argument is an integer, the weight is 100%. If the argument is a floating point number, the integer part of the number determines the preset number, and the floating point part of the number determines the weight. For instance, recallmulti 1.3 2.3 5.4 would weight preset 1 at 30%, preset 2 at 30% and preset 5 at 40%. Since weights are normalized, the total weight can be higher than 100%; for instance, recallmulti 1.5 3.5 6.8 would calculate correct weights (27.77%, 27.77% and 44.44% respectively), and recallmulti 1 2 3 , recallmulti 1.5 2.5 3.5 and recallmulti 1.99 2.99 3.99 all result in the same output (33.33% for each member).

Arguments:
  • weighted-pairs [list]

remove

The word remove , followed by a number, deletes the data for every object maintained by pattrstorage in a numbered preset. The number argument specifies the index of the preset to be removed. Any presets numbers higher than the specified index are automatically decremented.

Arguments:
  • index [int]

renumber

The word renumber renumbers stored presets into consecutive preset slots, beginning with slot 1.

resolvealias

The word resolvealias , followed by a symbol that specifies the alias of a client object, returns that object's full path name (if any) from the pattrstorage object's outlet, preceded by the symbol resolvealias .

Arguments:
  • client [list]

setall

The word setall , followed by a symbol that specifies the path name or alias of a client object and a variable number of additional arguments corresponding to the value of the client object, sets the value of the specified client object for all preset slots to that value. No data is sent to the client object itself.

Arguments:
  • client [list]

setstoredvalue

The word setstoredvalue , followed by a symbol that specifies the path name or alias of a client object, a number which specifies a preset and a variable number of additional arguments corresponding to the data expected by the client object, sets the value of the specified client object within the specified preset slot to the specified data.

Arguments:
  • client [list]

slotname

The word slotname , followed by a number and an optional symbol, sets the name of the preset slot specified by the number. If the symbol argument is not present, the name of the slot is removed. Undefined slots can be given names for labeling purposes. If a preset object is linked to the pattrstorage object, it will display the slot name of the corresponding pattrstorage slot.

Arguments:
  • index [int]
  • slotname [symbol]

storage_close

Closes the stored data window.

storagewindow

Opens the pattrstorage object's stored data window (the title bar reads storagewindow (name), where (name) is the patcher name of the pattrstorage object which created the window).

Arguments:
  • name [list]

store

The word store , followed by 1 or 2 arguments, stores data in a numbered preset. If the word store is followed by a number, the data for every object maintained by pattrstorage will be stored. If store is followed by 2 arguments--a symbol and a number--and the symbol argument matches the path name or alias of a client object, only the data for the specified object will be stored. The number argument always specifies the index of the preset to be stored. If the preset index specified by the number argument is already in use, the existing data will be overwritten without a warning.

A storage slot of '0' is allowed, but *IS NOT SAVED* in a file. It can be used as a temporary slot for interpolation activities or other non-permanent experiments.

Arguments:
  • client-and-index [list]

storeagain

The word storeagain simply executes a store operation, using the most recently-use preset slot. If there is no previously-used preset slot (if the store message has never been sent to the object), the message is ignored.

Arguments:
  • client [list]

storenext

The word storenext executes a store operation, using the next empty preset slot, counting up from preset 1. For instance, if preset slots 1, 2 and 4 have data stored in them, and the pattrstorage object receives the storenext message, the current state of the client objects would be stored to preset slot 3. A second storenext message would cause the data to be stored to preset slot 5.

Arguments:
  • client [list]

subscribe

The word subscribe , followed by one or more symbols, each corresponding to the path name or alias of an object, will add the specified object to the pattrstorage object's subscription list. See the subscribemode attribute for more information.

Arguments:
  • target [list]

unsubscribe

The word unsubscribe , followed by one or more symbols, each corresponding to the path name or alias of an object, will remove the specified object from the pattrstorage object's subscription list. See the subscribemode attribute for more information.

Arguments:
  • target [list]

write

The word write , followed by an optional symbol that specifies a filename, writes any preset data to a JSON file on disk. If the argument is given, and represents a valid file path, the file will be saved at that location - otherwise, a standard File Dialog will be presented for the user to manually choose a name and location for the file to be saved.

Arguments:
  • filename [list]

writeagain

The word writeagain writes any preset data to a JSON file on disk previously specified by the read or write messages. If no file has been previously specified, a standard File Dialog will be presented for the user to manually choose a name and location for the file to be saved.

Arguments:
  • filename [list]

writejson

The word writejson , followed by an optional symbol that specifies a filename, writes any preset data to a file on disk, in JSON format. If the argument is given, and represents a valid file path, the file will be saved at that location--otherwise, a standard File Dialog will be presented for the user to manually choose a name and location for the file to be saved.

Arguments:
  • filename [symbol]

writexml

The word writexml , followed by an optional symbol that specifies a filename, writes any preset data to a file on disk, in XML format. If the argument is given, and represents a valid file path, the file will be saved at that location--otherwise, a standard File Dialog will be presented for the user to manually choose a name and location for the file to be saved.

Arguments:
  • filename [symbol]
