preenfm2 and preenfm3 / Re: Two suggestions, two bugs and a question

I don't think so, as there was no PR for mods from p3_timefx_9.
i'm going to post the latest version in the paraphonic fx thread, so we can finalize those developments.

ah ok,
i think it's much easier to do such program in your regular pc : much cpu & ram available, many tools available.

yes, try puredata, it's free and very cool.

i think it would take too much ram to be done, unless some kind of sd card streaming, but i have no idea of the feasibility.

About the Fourier transform, you're talking about some kind of resynthesis which, i guess, would need lot of ram and cpu.

I feel that we would benefit more from some sound design utilities.
If you wish to investigate that way, i can suggest some work i done about sample mimiking with fm : https://github.com/pvig/preen-mutator
it's a puredata project which aim is to analyze an audio sample to get some metrics from it, and then generate random preenfm patch, to begin with,
then try to mutate it to make it converge to the audio sample.
(inspired from https://www.jstor.org/stable/3680541)

Well, it does not work very well, it's not really better than the random patch feature of the preenfm ::)
The good thing with this approach is that it would not need more cpu usage on the preenfm.

Maybe someone can pick up this idea an try to do something out of it ?

About the current features, here is another fw version with optimizations and slightly enhanced granular fx, especially Grain2 can now be tuned to the octave.

yes, it's based on 1.0
a note about the two granular fx : when the 2nd param >=1, audio is locked in a loop, so one can record a chord and then play over it (with Mix = 0.5 for example).

you can use the readme of https://github.com/pvig/preenfm2 to get a detailed list of the fx1, which were originaly made for the preenfm2
there is some iteration on basic filters, like lp2, lp3 etc.. , not usefull to have many, i guess it was done by a newbye dsp coder entusiast !
fortunatelly, Xavier was very wise to add some code to filter that fx list on display, (they remain usable by CC selection).
Maybe it would be a good idea to clean up that list again someday :-X

About phasing, allpass are basic filter blocks for that : https://en.wikipedia.org/wiki/Phaser_%28effect%29
just use a lfo to modulate it and you're phased !

yes, you can save the default Mixer with all needed parameters.

great !
it need a bit of optimisation in the granular part and maybe some enhancement ?

about the phaser effect, you already can do it in the FX1 section, with the allpass filters (Ap4 ..)

here we go  :)

delay is now a lot less lowpassed when feedback = 1

and if you want to test some new fx, there is two granular thingy...

other controls on a delay might be tone to affect the darkness of the tails to emulate an analog delay
ok, i think i understand better the request now : the delay are currently quite dark, ie lowpassed feedback, which give a quite short delay tail.
i will try to work out something about it.

Sometimes, limits is what we need.
but if you want more, here is an experimental version which let you use the Out menu to chain output from timbre 1 to timbre 2,
so you can have a chain of short delays.
it works only for timbres 1 to 3 (for some unknown reason).
For me it is a be too much of weirditude to be used, as it break the patch paradigm.
but if you want to have a look at it, here it is !

the git branch for this is there :

preenfm2 and preenfm3 / Re: Mixer select from midi
« on: June 06, 2023, 09:52:11 PM »
ah ok, thank you, it is very helpful.
I do it to make the mixer loading a little bit simpler, i scratched my head yesterday trying to load one, and i did not understood how it works at first.
As it's not the first time i face this, i thought it would be good to simplify it.

But now i have the need for a special track on my sequencer to handle this,
maybe i will stick to discrete program change, as it's so much easier.

sorry to bother, thanks for your help !

Thanks for that, using global midi make sense indeed !

preenfm2 and preenfm3 / Mixer select from midi
« on: June 06, 2023, 07:39:43 PM »
Hello Xavier,

lately I tried to recall Mixer files from midi,
but found it a bit tricky to do, because of the CC#0 & #32 to set before sending program change.

In my opinion, it would be much easier to use midi bank 127, and program change.
I don't think midi bank 127 is likely to be frequently reach anyway !

for now, I'm a bit lost in the code, i guess it should be done in MidiDecoder.cpp but i have a hard time figuring things out :P

i would be grateful for some help here ;D

midi echo is very cool on the midibox seq for example,
though i'm not sure how to implement this on the preen... maybe a special arp mode ?

There is also the modulator envelope loop trick, to mimick delayed notes !

Today i found this video about the Fugue Machine on iOS :

imagine this on the preenfm3 sequencer  ::)
