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

[Dan Stowell <danstowell@xxxxxxxxx>]

Hi -

You need to know one of the secret tricks of supercollider ;)

Change the name of your trigger control from "trig" to "t_trig", and
you will find it works just like you want it to...

(Controls beginning with "t_" are assumed to be trigger-type controls
and treated slightly differently)
