Substituting MKtls

Extension

Modality makes it easy to play the same process with different interfaces, which can be useful for many reasons: Playing may feel different, broken or lost interfaces can be substituted very quickly, etc etc.

This example show how to write your performance code so you can substitute very quickly when needed or desired.s.boot; ( // a simple sound Ndef(\blippy, { var snd = Blip.ar( \freq.kr(440).lag(0.1), \numharm.kr(100) ); Pan2.ar(snd, \pan.kr(0).lag(0.1), \amp.kr(0.5).lag(0.1)) }).play(vol: 0.25); // add a global spec for numharm param (the others exist as defaults) Spec.add(\numharm, [1, 50, \exp]); Ndef(\blippy).gui.parent.alwaysOnTop_(true); ) // make two MKtls: ( // a gamepad MKtl(\gp, "*drive"); MKtl(\gp).gui.parent.alwaysOnTop_(true); // and a nanokontrol2 MKtl('nk2', "korg-nanokontrol2"); MKtl(\nk2).gui.parent.alwaysOnTop_(true); ) // prepare the gamepad: // joystick axes for param control, // two buttons for start/stopping sound ( var k = MKtl(\gp); k.addNamed(\amp1, k.elAt(\joy, \r, \y)); k.addNamed(\pan1, k.elAt(\joy, \r, \x)); k.addNamed(\param1, k.elAt(\joy, \l, \x)); k.addNamed(\param2, k.elAt(\joy, \l, \y)); // while at it, prapare buttons for start and stop k.addNamed(\start1, k.elAt(\bt, \5)); k.addNamed(\stop1, k.elAt(\bt, \7)); ) // prepare the nanokontrol2: // 2 sliders and 2 knobs for param control, // and two buttons for start/stopping sound ( var k = MKtl(\nk2); k.addNamed(\amp1, k.elAt(\sl, 0)); k.addNamed(\pan1, k.elAt(\kn, 0)); k.addNamed(\param1, k.elAt(\sl, 1)); k.addNamed(\param2, k.elAt(\kn, 1)); // prepare buttons for start and stop k.addNamed(\start1, k.elAt(\bt, \S, 0)); k.addNamed(\stop1, k.elAt(\bt, \R, 0)); ) Ndef(\blippy).setUni(\numharm, 0.25) // now choose one of them, and set its actions // the same code can now be used for two very different MKtls! ( k = MKtl(\gp); // this one? k = MKtl(\nk2); // or run same code with that one! k.trace; k.elAt(\amp1).action_({ |el| Ndef(\blippy).setUni(\amp, el.value) }); k.elAt(\pan1).action_({ |el| Ndef(\blippy).setUni(\pan, el.value) }); k.elAt(\param1).action_({ |el| Ndef(\blippy).setUni(\freq, el.value) }); k.elAt(\param2).action_({ |el| Ndef(\blippy).setUni(\numharm, el.value) }); // and for start and stop: k.elAt(\start1).action_({ |elem| // only start on button down if(elem.value > 0) { Ndef(\blippy).play }; }); k.elAt(\stop1).action_({ |elem| if(elem.value > 0) { Ndef(\blippy).stop }; }); )
