Description
The mc.noteallocator~ object assigns voice numbers for MIDI and MPE note events using an optional multichannel signal to determine voice busy state. It also maintains a voice busy map used by other MC objects to avoid unnecessary processing for channels that are not actively playing notes.
Examples
Arguments
voice count [int]
If present, a number argument sets the maximum voice count. You can change the voice count during the lifetime of the object by setting the voices attribute.
Attributes
direct [int] (default: 0)
Set Busy Map With Signal Input
mpemode [int] (default: 0)
When mpemode is enabled, mc.noteallocator~ outputs the voice number contained in mpeevent messages instead of allocating a voice number based on its internal busy state. When using MPE mode, the source of incoming MPE messages (such as a keyboard or other device) assumes responsibility for the details of voice allocation. MPE mode is disabled by default.
name [symbol] (default: )
The name attribute assigns a global name to the object's busy map. By default, mc.noteallocator~ 's busy map does not have a name and is available only to MC objects within the same patcher. A named busy map is accessible to all MC objects (in any patcher) that refer to it using the busymapname attribute.
steal [int] (default: 1)
When steal is enabled, mc.noteallocator~ will re-allocate ("steal") a busy voice if it runs out of non-busy voices. The stolen voice number used will be the one least recently allocated. When steal is disabled, mc.noteallocator~ will not produce any output if all voices are busy. Output resumes only when a voice becomes free, either via the input multichannel audio signal or an incoming MIDI note-off event.
voices [int] (default: 0)
The voices attribute sets the maximum voice number mc.noteallocator~ will allocate and output. When voices is 0 (the default), the active voice count is determined by the number of channels in the connected multichannel signal. If there is no connected signal, mc.noteallocator~ defaults to 15 voices.
Common Box Attributes
annotation [symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.
background [int] (default: 0)
Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.

'72'
hidden [int] (default: 0)
Toggles whether an object is hidden when the patcher is locked.
hint [symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick [int] (default: 0)
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile [symbol]
JS Painter File
patching_rect [4 floats] (default: 0. 0. 100. 0.)
Sets the position and size of the object in the patcher window.
position [2 floats]
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation [int] (default: 0)
Sets whether an object belongs to the patcher's presentation.
presentation_rect [4 floats] (default: 0. 0. 0. 0.)
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect [4 floats]
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size [2 floats]
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
textcolor [4 floats]
Sets the color for the object's text in RGBA format.
textjustification [int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
varname [symbol]
