ack: ADSR envelope

[audionerd]

i'd like to sustain notes with ack.

maybe with a new argument to the SynthDef:

playbackMode = 0 // 0 for one-shot, 1 for ADSR

so that existing scripts would not have to change.

when set to 1 for ADSR, it would enable more arguments for the envelope:

volumeEnvDecay = 0.3
volumeEnvSustainLevel = 0.5
volumeEnvPeakLevel = 1

and maybe even

volumeEnvCurve = -4
volumeEnvBias = 0

when gate is 0, the envelope begins to close.

i have a prototype of this working for the Engine_Ack SynthDefs, and could submit a PR.

is there any interest in this feature for ack? or should it be part of a new engine?

FWIW I have a separate engine for this, but its not pushed yet (a poly Ack thing).

[audionerd]

Cool. Looking forward to your new engine.

@audionerd any chance you still have this working somewhere? There has been some interest expressed over on lines :)

[audionerd]

@notjustmat I only prototyped a change to the SynthDefs in an .scd, I never actually updated Engine_Ack.

Ah, sorry for the misunderstanding! I guess it is about time I get acquainted with the SC side of Norns :)
