Launchpad

Supercollider extension to develop a Novation Launchpad based interfaces similar to a GUI. The Interface is designed around the concept that you like to make your launchpad behave like a GUI with buttons and sliders. These widgets can be layered.

The library contains the following widgets:

LPButton, LPButtonArray, LPPushButton, LPPushStepButton, LPSlider, LPFaderH, LPFaderV, LPColorArea, LPInvisibleButtonArray

Installation

Use the Supercollider Quarks GUI:

supercollider Quarks.gui

Examples

Example of creating a button on the launchpad:

supercollider Launchpad.initMIDI; // before the Launchpad can be used it has to be initialized ( a = LPButton(Launchpad.getRange(0,0,0,0),{"Do something when the button is put to the front of the Launchpad.".postln},{"Do something when it is hidden from the Launchpad.".postln}); a.states = [LPLED.green,LPLED.red,LPLED.yellow]; a.action = {|b| "Print Current state:".post; b.value.postln; }; a.front; ) a.hide;// to hide the gui element

Example of a Slider:

supercollider a=LPSlider(Launchpad.getRange(0,1,0,7)); a.incrementArray=[1/80,1/160,1/400,nil,1/ -400,1/ -160,1/ -80]; a.color=\amber; a.background=\green; a.action={|s|s.value.debug(\slidervalue)}; a.default = 0.6 a.front
