Hey !

Thanks you for this code ! I have tried to modified this for my own code but i have not realy understand the collect and Ppar function.

My code but doesn't work: (if you have any idea for correct this your welcome :D):

w = Window("sequencer", Rect(0, 0, 400, 200)).front;

a = 16; a.do{| freq, i| NumberBox(w, Rect(i*25, 0, 25, 25)) .action_{ |v| a[i] = v.value; }; };

b = 16; b.do{| gate, i | Button(w, Rect(i*25, 25, 25, 25)) .states_([ ["0", Color.black, Color.white], ["1", Color.white, Color.black], ]) .action_{ |v| b[i] = v.value; }; };

Ppar([ a.collect({|c, r| Pbind( \instrument, \peep, \freq, Pseq(a[r], inf), \dur, 0.25 ) }), b.collect({|c, r| Pbind( \instrument, \peep, \freq, Pif(Pseq(b[r], inf).coin, 1, 0), \dur, 0.25 ) })] , inf).play;
