Re: [sc-users] envgen freeing synth immediatelly at synth start

[Peter Morris <PM@xxxxxxxxxxxxxxx>]

Miguel,

I modified your code slightly to use a new group so as not to trash my server:

(

g = Group.new;

x = SynthDef(\test, {

        var env = Env([ 1, 0, 0 ],[ 6, 0 ], \lin );

        EnvGen.kr(env, \gate.kr(0), doneAction:14).poll

}).play(g);

)

Yes, the freeing of the Group by doneAction: 14 frees both group and synth.  I changed the \gate to \gate.kr(1) and that, as expected, ran the envelope down to to zero, where the poll stopped.

Not exactly sure what outcome you are trying to achieve with \gate.kr(0) but I can confirm that the behaviours between DoneAction 2 and 14 are quite different..  PlotTree confirms what's happening, as I'm sure you've checked. . .

Ok, copied the wrong bit of code, the bug is only happening with
doneAction = 14, so this is the code that causes it:

(
x = SynthDef(\test, {

        var env = Env([ 1, 0, 0 ],[ 6, 0 ], \lin );

        EnvGen.kr(env, \gate.kr(0), doneAction:14).poll

}).play
)

this will immediatlly free the synth. This doesn't happen on any other
doneAction numbers. Hopefully others can reproduce this one.

best,
Miguel
