@maki : thanks for the ideas, these may be fun to try for some pseudo algorithmic music
i would also like to have polyphonic glide, maybe some sort of unison, and step sequence advance with note received.. i may try all those things later.. for now, i prefer to stay in the filter/fx context, to fullfill this part before starting something else.

@maki : thanks for the info, i wasn't aware of this. It may be possible to add a 4 points fm shaper on each slot, would have to make a poc.
Anyway, it's too much work for me at the moment, maybe in some months.

hi @maki, i guess you would like to have the parameter 2 available in the modulation matrix ?
if so, i tried to, but it failed.. (exception crash) because of my lack of understanding the structure of some part of the code (matrixParameterRow), and, according to the code comment( https://github.com/pvig/preenfm2/blob/master/src/synth/SynthState.cpp#L314), 8 destination target were removed in firmware 2.0, i think for a good reason, so i gave up...
for now, i use my digitakt to control param2 by CC, so i don't think i will dig this, sorry.
or maybe i misunderstood, what do you mean by tracking generator ?

hi guys!
i'm very glad you're enjoying my work !
i may leave the version like that, but don't hesitate to suggest ideas or requests,
it seem usable enough, so, i don't plan to add any other fx or change the fx list.
maybe polish it a bit, but would have better to really dive into sound design now .

good news, i found the "float cast" optimization and it make a big difference ,
i could bring back oversample on the lp3, hp3, bp3, peak filters !
for a test, i could have 4 parts running fast with per step program change, and it kept smooth !
the other optimizations was a good thing anyway..

hi @baxgas, thanks for the suggestion, i tried the regular version, but no luck..
so i changed my testing procedure, to be closer from real use case, and, yes, sadly, the cpu started to overflow very quickly. so, some radical optimisations needed !
i removed oversampling on lot of filters ; in a mix you won't hear the change i guess
+ removed lot of waveshaping, well, the good news is that it sound cleaner now (or cheaper )
now it seems to work well with a 4 track sequencing. it still may overflow if you really insist, so i will try to free more cpu cycle if i can..
i may remove lp2 & hp2 as these are still oversampled, and now lp & lp3 seems to be enough.

@baxgas, sorry for the messy project handling . Yes, that's because i added the new filters before distortions..
the processor is now a bit more busy than it was, i fear. i will now try to optimize my code more.

well, it seems i can't help trying things , and i find those filters really useful :

hi,
many thanks to @baxgas & @superfake to push me in the right direction, so in this version there is some more filters  :
Lp3 :  state variable filter, low pass mode
Hp3 : state variable filter, high pass mode
Bp3 : state variable filter, band pass mode
Peak :state variable filter, peak mode
Notc : state variable filter, notch mode
Bell :  state variable filter, boost if param amp > 0.5, else cut
BpDs: saturated bandpass filter

+ some rework on these fx to get a better use of the 2nd parameter  : Sat, Sigm, Fold, Wrap, Xor, Txr1, Txr2
+ the full range is back in lp2, hp2

hi,
ok, i will try things with that in mind.

thanks for your insight,
the mix parameter was a quick way to use the parameter 2, but you're right, it can get better use. i will review the possibilities.
i'm currently working on a notch filter, which may be useful for sure (if i can get it working )
