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:

Quarks.gui

Examples

Example of creating a button on the launchpad:

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:

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
