Manage voice numbers for events The mc.voiceallocator~ object assigns voice numbers to incoming messages 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 producing audio in response to events. Cycling '74 TEXT_HERE Multichannel signal representing busy state; any message along with specific messages to manage allocating and releasing voices. A multichannel signal connected to mc.voiceallocator~'s left inlet establishes a voice busy state. Typically you'll connect the multichannel output of audio triggered by events passing through mc.voiceallocator~. This permits you to hold a voice busy after an event that release a voice has been received.

Use event, endevent, and releaseevent messages to manage voice allocation. Busy Signal, Messages TEXT_HERE Messages Out Incoming messages are sent out the left outlet, preceded by an associated voice number out the right outlet. Voice Number An allocated voice number is sent immediately prior to its associated message is sent out the left outlet. Voice Count An optional argument can set a maximum number of voice numbers the mc.voiceallocator~ object will use. If no argument is supplied, the default voice count is 0, meaning that mc.voiceallocator~ will set its maximum voice count by the number of channels in a connected multichannel input. If there is no connected multichannel input, the default voice count is 16. Output voice number and bang The bang message is repeated to the left outlet preceded by a new voice number sent out the right outlet. Output voice number and value The number is repeated to the left outlet preceded by a new voice number sent out the right outlet. Output voice number and value The number is repeated to the left outlet preceded by a new voice number sent out the right outlet. Output voice number and list The list is repeated to the left outlet preceded by a new voice number sent out the right outlet. Output voice number and message The message is repeated to the left outlet preceded by a new voice number sent out the right outlet. Ends a named event The word endevent, followed by an event name defined by the event message, releases the voice associated with the event. The entire endevent message is repeated to the left outlet. Starts a named event The word event, followed by an event name and a message, sends the entire event message out the left outlet preceded by a newly allocated voice number. The name can later be used with the endevent message to release the voice that became associated with the event. Starts and holds a named event The word holdevent, followed by an event name and a message, sends the entire holdevent message out the left outlet preceded by a newly allocated voice number. The name can later be used with the endevent message to release the voice that became associated with the event. Unlike the event message, holdevent explicitly holds the named event until connected audio reaches zero. Print state of busy map Prints the current state of the mc.voiceallocator~ busy map to the Max Console as a list. Release voice The word release, followed by a voice number, releases that voice number (sets to a non-busy state). Without an argument, release sets all voices to a non-busy state. Release event without output The word releaseevent, followed by an event name defined by an event message, releases the voice number associated with the named event but unlike endevent, does not produce a message out the left outlet. Sets busy state Connect an optional multichannel signal to prevent mc.voiceallocator~ from reallocating a voice until the corresponding channel's signal level goes to zero. Initial Busy State Sets the initial busy state. The default value is 1. Set this to zero to avoid high CPU usage before sending events when audio is turned on. Busy map name The name attribute assigns a global name to the object's busy map. By default, mc.voiceallocator~'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. Voice Stealing When set to 1, the steal attribute allows messages to pass through mc.voiceallocator~ and are assigned to voice numbers when all voices have been allocated. When set to 0, messages are not passed through and are not assigned to voice numbers if all voices are already allocated. Voice Count The voices attribute sets the maximum voice number mc.voiceallocator~ 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.voiceallocator~ defaults to 16 voices.
