hi Xavier,
don't worry about the recent commit : i tried to make allpass filter frequency velocity dependant, was not useful, it was a regression ; last commit just put it back to a previous state.


BP2 : yes it doesn't work very well, it was a attempt to double sampling the original algo.

Peak: ok, i modified the reso curve response. there a small click when reso = 1, could not get rid of yet...

Notch: the resonance has expected behaviour, but, yes , this algo don't go very very high

BpDs : self oscillation is not expected, i modified this in my last commit

Pann : this one is a mixture of panning and 3x lowpass with different frequency spread around f

Sat : yes, it is a very simple digital distortion, sounds as expected.

LpSn : pos is an offset for a transfer function, add distortion, depending on pos and number of voices played. i let param1 control it to allow variable distortion. try it on a pure sin poly patch to use it a its best.

Not4 : quad notch filters, use it with a slow lfo for phasing effect

18db : ok, fixed this in last commit

La+d: ok, yes the ladder filter department is quite crowded, why not removing Lad+, Diod and L+d+

about the h3o+ (tb like) : i reworked the dynamics and accent circuit in one of my last commit if you want to check it out.

@observer , please check in menu Tools > Set > Receives = CC & NRPN
that may be the cause your issue.

ok, the accents may be useful after all ;)
i got it back in my last commit, with small tweaks.
that 303 thing is quite difficult to get it right..

hi @Xavier,
many thanks for integrating some filters !

about the Xor, Txr1, Txr2, LPx1, LPx2 filters :
yes i also think that Xor, Txr1, Txr2, LPx2 may not be so interesting, those may be all be replaced with only LPx1.
it's my favorite one from this ensemble ; it allow progressive signal destruction and/or digital glitchy texture.

thank you for pointing me the velocity problem, i removed the accent thing as it can be done with other ways.
i did too much code lately and not sleeping enough ::)

@observer : the filter CC should work, i checked this today without any problem.

@matrix12x : please check this one, there is 3 version of the formant filter
Oryx : 2 peaks formant filter with some distortion
Orx2 : 3 peaks formant filter
Orx3 : 3 peaks formant filter + more distortion (mono)

+ a bunch of ladder filters
18db : 3 pole soft LP
La+d: ladder version 1
Lad+: ladder version 2
Diod: ladder version 3
L+d+: ladder version 4

hi guys,
thanks for the support :)
@matrix12x : ok i will give it a try, but i fear it has to be a mono filter because the formant filter is quite cpu intensive.
however, i will try to find a lighter algo.

@baxgas i'm glad you like  :D
but it's still in progress ! i had lot of experiments with allpass filters lately, those are useful to had a little spectral blur in the sound.. it's subtile but the sound quality is a little bit enhanced with it.
So i put some allpass filters here and there as these are not cpu intensive..
And then the 3 previous Not3, Ap3, Ap3b are now Not4, Ap4 and Ap4b (1 more pole!)
+ 2 new filters :
Ap4D : another allpass quad flavour
Oryx : 3 bandpass formant filter, quite fun to play with ;)

Sigm distortion has been reworked : it use now a more efficient formula and the sound is a little bit more dynamic.

here is a version with 3 more filters, for sound design and phasing fun :)

changes are :

Not3 :
  triple notch filter, Sprd to spread the 2 poles around the center frequency
Ap3 :
  all pass triple filter, Sprd to spread the 2 poles around the center frequency
Ap3b :
  all pass triple filter, resonant version, Sprd to spread the 2 poles around the center frequency

Reworked pann fx :
  stereo placement tool : pos = panning, sprd = 3 x pole spread

Slight modification of the Txr1&2, LPx1&2

yes it work fine now ! thanks !
it allowed me to fix some performance issues i wasn't aware of ;)

 :-[ Sorry, there was a bug in the two new fx, i replaced the two files with fixed version in previous posts.. they now sound as it should.
@Xavier, thanks for the hints, and the cpu usage will be very very useful ! but unfortunately i have missed something as the displayed % was stuck at 0 when i tested.. i will investigate more this weekend.

@baxgas, yes the fold parameter add more weirdness to an already weird fx :).
but for a more common use, i made some minor changes to the resonance of some filters to make it cleaner : it did not work so well in a polyphonic situation.
So i added two fx for that ; LpSn & HpSn, which are soft to medium distortion. the signal is not crushed like with others distortion when you play many notes.
i like to use LpSn on sine based pads : there is a sweet spot that give a nice analog feel ;)
