SuperCollider CLASSES

ProgramChangeResponder

allow functions to be registered to respond to MIDI program change events
Inherits from: MIDIResponder : Object

Description

NOTE: SC 3.5 added the MIDIFunc and MIDIdef classes. These are faster, and aim to have a more convenient, logical and consistent interface, which shares a common design with OSCFunc and OSCdef. They also provide support for all MIDI message types.

Class Methods

*new (function, src, chan, value, install: true)

Arguments:

function

A Function to be evaluated. Arguments passed to the function are: src, chan, value.

src

The src number may be the system UID (obtained from MIDIClient.sources[index].uid) or the index of the source in the MIDIClient.sources array. nil matches all.

chan

An Integer between 0 and 15 that selects which MIDI channel to match. nil matches all. May also be a Function which will be evaluated to determine the match. eg: { |val| val < 2 }

value

An Integer between 0 and 127 that selects which program change number to match. nil matches all. May also be a Function which will be evaluated to determine the match. eg: { |val| val >= 4 }

install

If true, then if the midi event is matched, cease testing any further responders. Note that doing this will prevent any other responders of this type from responding, including ones added behind the scenes in classes. Note also that this functionality is sensitive to the order in which responders are added.

        [src,chan,val].postln;
        },
        nil, // any source
        nil, // any channel

    )

(
    c = ProgramChangeResponder({ |src,chan,val|
        [src,chan,val].postln;
        },
        nil, // any source
        nil, // any channel
        (50..60) // within this value range
    )
)
