fade curves not working properly

[woutersnoei]

I ran into problems with a previously saved file after the fade curves addition. With a non-release-self event of 6 seconds, with also a fadeOut time of 6 seconds it doesn't work and can even blow up. Have to invesigate further what and where exactly goes wrong, but I've disabled the line: 5, Dseq( [ fadeInCurve, 1, fadeOutCurve, 1 ], 1 ), for now in UEnv just to get the performance I'm doing to run properly, and it works as it should now (without actual sounding fade curves of course)..

Oh, very sorry about that. :-( I have been running that code for a while, with a couple of performances in between too, and never hit any problems... I will look at it asap.

A reproducer:

UScore(UChain(0,0,6, false, \sine,\stereoOutput).fadeOut_(6)).prepareAndStart

Hum, I don't think the problem is in DemandEnvGen but in the other Env, polling the gate parameter, with releaseSelf = false it's already 0 on the first block and this appears to be causing to free the synth immediately instead of doing the fadeout.

Env([ 1, 0, 0 ],[ fadeOut, extraSilence ], \lin, 0 ) .kr( doneAction, RunningMin.kr( gate.poll(label:"gate") ) + Impulse.kr(0) )

Commenting out the code above the synth will play fine. This is on sc3.7 dev.

So if the u_gate is already zero at start the synth will free immediately.

(
x = {
    WhiteNoise.ar(mul:0.01) *
    Env([ 1, 0, 0 ],[ 6, 0 ], \lin, 0 )
    .kr( 14, RunningMin.kr( \gate2.kr(0) ) + Impulse.kr(0) ).poll

}.play
)

In the synth above poll only posts once and the synth quits immediately. If I start the synth with \gate2 at 1 and then set it to 0 then it works fine, it does the fade out. Can you reproduce this in sc 3.5 also ? So if this is what is causing the problem, I wonder how is it that before it was working ?

I already spotted some unrelated mistakes in there (the Env doesn't have fadeCurves) that I can correct.

Rolling back to commit 2419ee9b988ebd1da6197de906220d79603630fc , before the fades were added I see the same issue (on sc 3.7). Are you sure this is related to the fade curves ?
