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

[Dan Stowell <danstowell@xxxxxxxxx>]

One approach: Sometimes I have a single long-running synth for a
percussion instrument (as opposed to one synth per event), with a
t_trig input. Then you can trigger it with things like

Pbind(
  ...
  \trig, Pseq([0,0,0,0,1,0,0,0.5,  0,0.5,0,0,1,0,0,0], inf),
  ...
)

Here the triggers are maybe being used for velocity as well as
triggering of a snare.
