Title: add matrix destinations
Post by: solipsvs on October 15, 2021, 10:19:22 PM

is there any way we could add matrix destinations for all filter parameters please (if they exist or not)?  this will go a long way to making pfm2/3 a sound designers tool.  i will personally buy you a beer!

You're talking about the second parameter ?
The first one is available. The last one of the list : Filtr

The second one is not available because for many filter Types it requires lots of variable to be re-calculated. So with an LFO on it that would have a performance impact.
In adition smooth transition between 2 values is not garanteed.

Do you have a specifc filter type in mind for which you would like that ?

well any of them that is possible.  if a knob can be twisted and an effect achieved, it would be nice to point a matrix slot there.  but specifically, it would be great to modulate the wrap drive, tone and gain to add some character to a patch (because im unable to get that distortion to fade out even after tweaking the amp envs).  but every filter parameter deserves it honestly. i feel like its a missed opportunity to make preenfm a more current sounding synth. i often want to dynamically tame a sound after it is distorted.  the formant filter deserves parameters as destinations too.  most of the subtractive filters would be a good choice too.

hello,
i had a go at adding the filter param2 to the modulation matrix.
Done it for the pfm3 as it's much easier to develop for.
I did it for all filters but the BP, which need too much processing.
The cpu footprint should be ok for the others, so here is a .bin if you want to check it out.

For @Xavier, i did a PR in github, to make modifications easier to read :

Thanks  :)
I'll try to make the 0.109 pfm3 firmware available this week end.
