MIDI Controller Class for SuperCollider

Based in Controller class for Arturia BeatStep, mapped to factory defaults (actual controller defaults, which differ from the data sheet).

Install:

Copy MCClass.sc to SuperCollider Extensions folder and recompile class library from scide or command line.

Basic usage

~mpkmidimix = AkaiMidiMix();
~irigpad = IRigPads(); 

//master volume (SC in DB)
v = s.volume;
~irigpad.knob4.onChange = {|val| v.volume = val.linlin(0, 127, -10, 10) };

a = ArturiaBeatStep();

// register a function to be evaluted when fader1 is changed
a.knob1.onChange = {|val| (val/127).postln };

// overwrite the previous assignment
a.knob1.onChange = {|val| val.linexp(0, 127, 20, 20000).postln };

a.pad1.onPress = { "Hello, ".post };
a.pad1.onRelease = { "Arturia BeatStep!".postln };

Incremental assignment

It is possible to incrementally assign the knobs and pads.

a = ArturiaBeatStep();

a.knobs.do {|knob, i|
    knob.onChange = {|val|
        "Knob % value %\n".postf(i+1, val);
    };
};

a.pads.do {|pad, i|
    pad.onPress = {|val|
        "Pad % pressed %\n".postf(i+1, val);
    };

    pad.onRelease = {|val|
        "Pad % released %\n".postf(i+1, val);
    };
};
