Controlling SC with the Mouse

A quick way of control is often needed when testing and designing synthesis and processing algorithms in SuperCollider. One quick way is to map the mouse position to control rate buses. Combined with a touch display, this can even be an interesting means for expressive control. This example first creates a control bus with two channels. The node ~mouse uses the MouseX and MouseY UGens to influence the two channels of this bus:

// mouse xy controll with busses
~mouse_BUS = Bus.control(s,2);

~mouse   = {
  Out.kr(~mouse_BUS.index,   MouseX.kr(0,1));
  Out.kr(~mouse_BUS.index+1, MouseY.kr(0,1));
}.play;

Use the mouse example with the previous sawtooth-filter example to control pitch and filter characteristics.
