Re: [sc-users] Drum patterns with patterns?

[Paul Jones <pauljones_mds@xxxxxxxxx>]

I've just spent quite sometime programing beats in SC, I tend not to use
patterns but arrays and probabilities. 

i.e

~spaff = [0,0,0.5,0.2,1,0,0.2,0.4,0.5]

n = 16

Routine{n.do { |i|

~snare = ~spaff[i%spaff.size];

case{~snare.coin}{Synth(\bigFATAMENSNARE,[\vel,~snare,\dec,~snare])};

(1/4).wait


   }}.play



also look at the convertRhythm class for making interesting wait times.
