« on: October 06, 2019, 01:01:09 PM »
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

i was not fully satisfied with the LPx1 & 2 fx, so here is a reworked version : in these, i replaced the mix parameter by a fold parameter

@superfake : sorry, my bad, the rollback was not well made, now it should be ok.

@superfake , thanks for the feedback,
yes you're right, i prefer the previous version as well
in this version the 3108 sound is back on fold and sigmoid ! and it's not so cpu hungry after all
i also fixed a problem on lp2, hp2 when extremely modulated, the filter went off..
@maki, you don't need much software to try things on the pfm2 :
https://code.visualstudio.com/ to edit the code
arm-gcc version 4.7 (see https://github.com/Ixox/preenfm2 )
and git would be helpful but not mandatory (https://git-scm.com/)
but if you're not much into programming, i would suggest you to test puredata, or easier, get an axoloti (http://www.axoloti.com/) and have a ton of fun creating crazy things !

@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 ?
