[sc-users] reset playbuf trigger using Synth.set

[jesus gollonet <listas@xxxxxxxxxxxxxxxxx>]

Hi all.

I'm stuck with what I believe to be a shamefully simple problem.
I have this simple playbuf synthdef

  
   SynthDef(\pbf, { |out = 0, bufnum = 0, rate = 1, amp = 0.5, trig=0|
       Out.ar(out,
           Pan2.ar(
               PlayBuf.ar(1, bufnum, BufRateScale.kr(bufnum) * rate, trig),
               level:amp
           )
       )
   }).memStore;

which I'm going to use for short percussive sounds, and I'd like to be 
able to trigger it using Synth.set instead of creating a new Synth every 
time, ie:


   a = Synth(\pbf, [\bufnum,~b4])
  
   // each time I do this I should hear it. but only hear it the first 
time.
   a.set(\trig,1)
   a.set(\trig,1)
   a.set(\trig,1)
  
the problem is that trig is only triggered when I change from <=0 to >0 
so I have to manually reset the trigger each time:

   a.set(\trig,1)
   a.set(\trig,0)
   a.set(\trig,1)

and I've been looking for a way to auto reset the trig, but no luck 
yet... any pointers?

Thanks a lot!
jesús.
