I am the operator of my SuperCollider GUI

.cc - week one.

This is my first experiment with creating a GUI in SuperCollider. It's a "Gain Envelope" program, an idea I borrowed from Peak. Note that at this stage it's a bit like Anna Kornikova, it looks good but doesn't actually do anything.

SuperCollider has plenty of options for the creation of UI's. I had a look at a video on youtube that uses the WiimoteLib class to use a Wii controller with SC.

var a, env, c, combo, comboInfo, loadButton, saveButton, previewButton, soundFile;

//window
a = GUI.window.new( "Gain Envelope...", Rect(158, 185, 360, 315));
a.view.decorator = FlowLayout(a.view.bounds);

comboInfo = ["Fade In", "Fade Out", "Retro Synth", "Random"];
combo = SCPopUpMenu(a, Rect(10,10,100,20));
combo.items = comboInfo;
combo.background_(Color.white);
combo.action = {/*ACTION*/};

//envelope
env = SCEnvelopeView(a, Rect(0, 0, 350, 100))

f = SoundFile.new;
f.openRead("sounds/a11wlk01.wav");

soundFile.soundfile = f;
soundFile.read(0, f.numFrames);
soundFile.elasticMode = true;

soundFile.timeCursorOn = true;

soundFile.gridColor = Color.white;

soundFile.timeCursorColor = Color.grey;
soundFile.setSelectionColor(0, Color.grey);
soundFile.timeCursorPosition = 2050;
