Re: [sc-users] Ppar select random array from array of arrays

[kennethflak@xxxxxxxxxxxxxx]

Thanks for the tip! Unfortunately this doesn't work either, getting an 'The preceding error dump is for ERROR: ListPattern (Ppar) requires a non-empty collection; received a Pfunc.'

In the end, I managed to make it work by creating an array of Ppars instead and playing them with a Pseq:

patterns = [bass, treeperc, lead, lead2, kick, bubbles].powerset.reject({|i| i.size < 2}).scramble;
ppar = patterns.collect{|i| Ppar(i)};
pseq = Pseq([Pfindur(2, Prand(ppar))], inf).play;
