ScGrids

Extension

Description

SuperCollider port of drum sequencer Eurorack module Grids by Mutable Instruments used in form of a Pattern via Pbind.

If you want to use it in a Pbind check out the the pattern implementation Pgrids and PgridsValue.

A GUI which mimics the handling of the original module can be found in the examples.

For more information check the manual of the module https://mutable-instruments.net/modules/grids/manual/

Example of multiple Tdefs mapped to the sequences of ScGrids which parame are controlable via a GUI.( // some basic drum synths SynthDef(\kick, {|out| var sig = SinOsc.ar(XLine.ar(start: 600, end: 50, dur: 0.1)); var env = EnvGen.kr(Env.perc(releaseTime: 0.25, curve: 5.0), doneAction: Done.freeSelf); Out.ar(out, Pan2.ar(sig*env*\amp.kr(0.5))); }).add; SynthDef(\hh, {|out| var sig = WhiteNoise.ar*EnvGen.kr(Env.perc(releaseTime: \release.kr(0.2)), doneAction: Done.freeSelf)*\amp.kr(0.5); sig = LPF.ar(sig, freq: \ffreq.kr(4000)); Out.ar(out, Pan2.ar(sig, \pos.kr(0.0))); }).add; ) ( // setup a clock t = TempoClock.default; t.tempo = 130/60.0; // tdefs to play patterns Tdef(\hh, {|env| inf.do({|i| var level = ScGrids.calculateLevel( instrument: \hihat, curBeat: i, x: env.x, y: env.y, ); if(level>=(1-(env.density)), { ( instrument: \hh, amp: level, release: level.linlin(0, 1.0, 0.0, 0.04), ffreq: 1000 + (exprand(1000, 6000) * level), ).play; }); (0.125).wait; }); }).clock_(t); Tdef(\k, {|env| inf.do({|i| var level = ScGrids.calculateLevel( instrument: \kick, curBeat: i, x: env.x, y: env.y, ); if(level>=(1-(env.density)), { ( instrument: \kick, amp: level, ).play; }); (0.125).wait; }); }).clock_(t); Tdef(\sd, {|env| inf.do({|i| var level = ScGrids.calculateLevel( instrument: \snare, curBeat: i, x: env.x, y: env.y, ); if(level>=(1-(env.density)), { ( instrument: \hh, amp: level, release: level.linlin(0, 1.0, 0.0, 0.2), ffreq: 4000 + (exprand(1000, 4000) * level), ).play; }); (0.125).wait; }); }).clock_(t); // set default values for tdefs [\hh, \k, \sd].do({|instrument| [\density, \x, \y].do({|val| Tdef(instrument).set(val, 0.5) }); }); // GUI for tdefs w = Window("SC grids", Rect(100, 100, 400, 580)); [\hh, \k, \sd].do({|instrument, num| Slider2D(w, Rect(20, 20 + (180*num), 150, 150)) .x_(0.5) .y_(0.5) .action_({|sl| Tdef(instrument).set(\x, sl.x); Tdef(instrument).set(\y, sl.y); }); StaticText(w, Rect(200, 20 + (180*num), 100, 20)).string = instrument; StaticText(w, Rect(200, 60 + (180*num), 150, 20)).string = "density"; Slider(w, Rect(200, 95 + (180*num), 150, 20)) .value_(0.5) .action_({|sl| Tdef(instrument).set(\density, sl.value); }); Button(w, Rect(200, 120 + (180*num), 100, 40)) .states_([ ["play", Color.black, Color.green], ["stop", Color.black, Color.red], ]) .action_({ var tdef = Tdef(instrument); if(tdef.isPlaying, {tdef.stop}, {tdef.play}); }); }); w.front; )
