preenfm2 and preenfm3 / Re: New filters

hi guys!
i'm very glad you're enjoying my work ! :D
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 :D,
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.. 8)

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 :o !
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 :D (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 :

and here is the version with volume compensation fix for the SVF filters :D.

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 :P )

@baxgas, yes it is quite crowded in the fx department now !
for me, the main use of filters is to fine tune the instruments, to make them work well with other instruments ; i want to use the preenfm in a minimal setup with a drum machine, the main output should be good enough as is, with its 4 instruments mixed. So i must cut the bottom of some, emphasize the mids of others, etc... to let the lead instrument have enough space ; this one can have some grit, unusual fx..

for now, i would nearly keep all, but I need to play with it more to be sure about this.
what one would you remove/keep ? what would be your use/need of the fx ?

hi guys, thanks for the support !

added two new ones :
BP3 is another BP flavour
LPws is a distorted lowpass, to mix with the source to enhance presence

@baxgas : good idea, i modified the readme to give some infos about the fx (https://github.com/pvig/preenfm2)
about delays, phaser etc, these kind of fx require memory that we don't have left on the preen, i fear..
but you can already patch fm to sound like a chorus (kind of) with careful detuning, or simulate a delay with the free env 2 loop !
like this https://www.youtube.com/watch?v=GYFD1lmk-lo

i will have a second look at the possibility to modulate fx param 2 in the matrix, but at first sight it seemed quite some work..

and then the master version.

while i was at it, i added a new filter : a crossfade between lp & hp across the frequency range.
enjoy !
