Envelope as modulator - changes needed.

[lalalandsynth]

When using an envelope as a filter modulator , it goes from 0 to cutoff , this is wrong.
It should be able to go from the filter cutoff and UP , so, it adds to the filter cutoff.

Maybe the envelope could have an offset value that could track the filter cutoff ?

Working on doing this is scriptnode with some hacks but should be possible on the default envelope.

You can do this with a table envelope or script envelope

@d-healey

Table envelope : How so , for me it always goes up to the cutoff point.

Script envelope . Tried it , not much luck so far , but admittedly I might easily be missing something in scriptnode ?

[d.healey]

@lalalandsynth If you set the cutoff to 20kHz then you can use the table envelope to start/end at any point.

Script envelope doesn't need scriptnode.
Edit: actually maybe it does, I thought it was like a scripted voice start modulator but seems it's something else.
Edit2: Seems it used to be like the voice start modulator because that's what the docs show.

2 Questions .

1. I am assuming you mean like this ?
   This way I cannot get to to close properly , not full range.
   

2. Should the AR envelope affect the filter envelope like that ?

@d-healey This does not do anything over here ? I am starting to feel stupid .

[d.healey]

I don't think your eyes have a refresh rate of 15ms :p Use your ears instead or increase the attack time.

[lalalandsynth]

@d-healey oh, I get it to work now .. this is a workaround in my opinion...but something ! quite fiddly.

Do you suggest then using a Filter cutoff knob connected to the first table value and switching over to the filter freq knob when the envelope is disengaged ?

[d.healey]

@lalalandsynth You mean for front-end control for the user?

[lalalandsynth]

@d-healey Yes, a typical example I have in mind is to apply the ADSR/Vca envelope or a unique envelope to the filter ,with amount , while being able to use a cutoff knob for the filter. Thereby offsetting the whole thing.

[d.healey]

Then I think your idea sounds fine.

[lalalandsynth]

Ok, trying that .
I am a bit obsessive ... :P

EDIT: Turns out that the table cannot be used as realtime cutoff connected to a knob , jumps values while sweeping , very noticable from 0-1%.

Also , if you hold it long enough , it jumps to the top after the Attack stage is finished.

And for some reason , some poly issue the Simple envelope on the VCA affects the later table envelope . Dont really understand that.

This whole thing should be simpler to do.
Again, maybe an 0 offset control on the adsr , connected in this case to the filter.
Something like that , not sure what would be the best way.
