Output numbers from a notation display

nslider

Description

nslider or "Note Slider" is a musical-notation-based integer value slider.

Examples

Arguments

None.

Attributes

bgcolor [4 floats]

Sets the background color for the object in RGBA format.

clefs [int] (default: 1)

Display Clefs

fgcolor [4 floats]

Sets the foreground color for the object in RGBA format.

mode [int] (default: 0)

Sets the nslider object's mode of operation.
Monophonic: (the default) Only one note can be selected and displayed at one time.
Polyphonic: The kslider object keeps track of note-ons and note-offs, so it mirrors which notes are currently held down on your MIDI keyboard. A key is “turned off” by sending the kslider object a key on message with a velocity of 0. Possible values:

0 = 'Monophonic'
1 = 'Polyphonic'

parameter_enable [int]

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

Parameter Attributes

Order

Typeint

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 Enable

Typeint

Parameter Mode Enable (not available from Parameters window)

Link to Scripting Name

Typeint

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

Long Name

Typesymbol

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

Short Name

Typesymbol

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.

Type

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/Enum

Typelist

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 Mode

Typeint

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

None
Unipolar
Bipolar
Additive
Absolute

Clip Modulation Range

Typelist

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

Initial Enable

Typeint

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

Initial

Typelist

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

Unit Style

Typeint

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 Units

Typesymbol

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").

Exponent

Typefloat

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.

Steps

Typeint

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 Visibility

Typeint

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)

Typeint

Speed limits values triggered by automation.

Defer Automation Output

Typeint

Defers values triggered by automation.

Messages

bang

In left inlet: Sends out the pitch and velocity values currently stored in nslider.

int

Arguments

input [int]
The number received in the inlet is displayed graphically by nslider if it falls within its displayed range. The current velocity value (from 1 to 127) that nslider holds is sent out its right outlet, followed by the received number out the left outlet.

  (inlet1)

Arguments

velocity [int]
In right inlet: The number received in the right inlet sets the output key velocity without triggering output.

float

Arguments

input [float]
In left inlet: Converted to int.

  (inlet1)

Arguments

velocity [float]
In right inlet: Converted to int.

list

Arguments

value-pair [list]
A list of two numbers sent to the left inlet of nslider can be used to set and output the note and velocity values.

anything

Arguments

notenames [list]
Notes can also be added using the musical note name and octave, i.e., F#3. This is especially useful for forcing display of accidentals (# or b). For example, a value of 59 and the message Cb4 both produce the same note, but the number will display a B note while the message displays a C-flat.

chord

Arguments

value-pairs [list]
In left inlet: The word chord, followed by a list of MIDI note name and velocity pairs, can be used to play chords on the nslider in polyphonic mode (set by the mode 1 message). The chord message sends note-offs for currently held notes, followed by note-on commands for the specified note and velocity pairs. When the nslider object's state is saved by a preset object in polyphonic mode, the preset object will store chord messages.

clear

In left inlet: The clear message will clear any notes on the staves, but will not trigger any output.

flush

In left inlet: When the nslider object is in polyphonic mode (set by the mode 1 message), the flush message will send note-offs to currently held notes and clear the nslider object's display.

(mouse)

nslider also sends out numbers when you click or drag on it with the mouse. The velocity value is determined by the previous value received in the right inlet.
If the nslider object is in polyphonic mode, you need to click on a note twice: once to send a note-on and draws the note, and once again to send a note-off and erase the note.

set

Arguments

value-pair [list]
In left inlet: The word set, followed by a number, changes the value displayed by nslider, without triggering output. If the set message is followed by two numbers, both the note and velocity values are set, without causing output.

Output

int

nslider sends its current velocity value out its right outlet, followed by the (displayable) pitch value out its left outlet, when a number is received in its inlet or you click or drag on the object. In polyphonic mode, it will send a note value with a velocity of zero when a note is removed from the staves.
