kslider

Output numbers from an onscreen keyboard

Description

Outputs and displays note and velocity information using an on-screen keyboard.

Arguments

None.

Attributes

blackkeycolor[4 floats]

Sets the color for the upper level of keys (otherwise known as the black keys) in RGBA format.

hkeycolor[4 floats]

Sets the selected key color in RGBA format.

inputmode[int]: 0

Set how incoming MIDI is interpreted. Possible values:

0 = 'Off' ( Input passed unclipped to output )
1 = 'MIDI' ( Input clipped to 0-127 )
2 = 'Visible' ( Input clipped to visible range )

mode[int]: 0

Sets the kslider object's mode of operation.
Monophonic : (the default) Only one key 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.
Touchscreen : Same as polyphonic, except touch up and mouse up events send out note offs. Possible values:

0 = 'Monophonic'
1 = 'Polyphonic'
2 = 'Touchscreen'

offset[int]: 36

Sets an offset value in octaves for the kslider object.

param_connect[symbol]:

Establishes a two-way connection between the object and a parameter of a compatible object with parameters such as gen~ or jit.gl.slab. The object can be used to change the value of the parameter and will update if the parameter value changes. The easiest way to set param_connect is with the attribute's menu in the inspector or the Connect submenu of the Object Action menu. The menu displays all available parameters of compatible objects.

Setting the param_connect attribute with a message requires the target parameter's path, which is the host object's scriping name followed by two colons and the parameter name. For example, for a gen~ object with scripting name gen~_AB , the path of the freq parameter would be gen~_AB::freq . You can set a value for the param_connect before the host object or parameter exists, and the object will connect to the parameter once it exists. Refer to the user guide entry for param_connect for more details.

parameter_enable[int]

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

parameter_mappable[int]: 1

When parameter_mappable is enabled, the object will be available for mapping to keyboard or MIDI input using the Mappings feature.

range[int]: 48

Sets the number of keys in the keyboard display.

selectioncolor[4 floats]
7.0.0

Sets the color for the currently active keys in RGBA format.

style[symbol]:
7.0.0

Sets the style to be applied to the object. Styles can be set using the Format Palette.

whitekeycolor[4 floats]

Sets the color for the lower level of keys (otherwise known as the white keys) in RGBA format.

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

bang

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

int

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

Arguments:
  • pitch [int]

  (inlet1)

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

Arguments:
  • velocity [int]

float

Converted to int .

Arguments:
  • pitch [float]

  (inlet1)

Converted to int .

Arguments:
  • velocity [float]

chord

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 kslider 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 kslider object's state is saved by a preset object in polyphonic mode, the preset object will store chord messages.

Arguments:
  • value-pairs [list]

clear

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

flush

In left inlet: When the kslider 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 kslider object's display.

(mouse)

The kslider object sends out numbers when you click or drag on it with the mouse. The velocity value is determined by the vertical position of the mouse within each key. Higher vertical positions produce higher velocities, to a maximum of 127.
If the kslider object is in polyphonic mode, you need to click on a key twice: once to send a note-on, and once again for a note-off.
Clicking on the very rightmost edge of the kslider sends out the note of the key C that would be just to the right of the keys that are visible.

set

In left inlet: The word set , followed by a number, changes the value displayed by kslider, without triggering output.

Arguments:
  • pitch [int]
  • velocity [int]

size

This is a legacy message - the size of the kslider object can be set by clicking on the object's resize handle and dragging.
In left inlet: The word size , followed by a zero or one, sets the size of the keyboard display. size 0 (default) sets the large keyboard, and size 1 selects the small keyboard.

Arguments:
  • size-flag [int]

Output

int

kslider 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.
