preenfm2 and preenfm3 / Preen editor in browser

« on: March 05, 2026, 08:14:03 PM »

Hello,

What if you could edit the preenfm directly from your browser?
I built a small React app to experiment with the idea—here it is  .

https://preen-web-ui.vercel.app/


It’s very early, but it already works and can edit patches from the browser.

Source code:
https://github.com/pvig/preen-web-ui

Feel free to play with it, improve it, or send PRs.

The 4 presets names, String / Wood / Gong / Cymb is a joke, with only 4 modes one can only evocate thoses sounds .
But it is noneless useful for timbre shaping, i guess.

re attached the file in first post : levels of resonators was too high (x4), sorry for that.

Here is the result of some more experimentation around the paraphonic filters.
It's an attempt to get some aspect of Mutable Instrument Rings into the preen, so here are some new fx :

Plck : a karplus-Strong classic pluck algo, with a twist : the frequency of notes is taken from the Scala keyboard mapping
Plk2: same as Plck except midi notes only trig notes, pitch is set with the matrix
Moda: a simple 4 modes resonator, which can morph thru 4 presets, String / Wood / Gong / Cymb

hi Dave,
a useful post if i must say ^^

It would be very cool if you could remember the settings that make hang the pfm3.

About the CC 40-45, yes it's far from ideal : they respond to the global midi channel to change some reverb params.
CC40 is for reverb preset change, CC41 to 45 are reverb params, that are overwriten when CC40 change the preset...
well, it's a really weird implementation

CC40 may be used for something else ?
What do you think about it ?

hi,
here is a fw built with that missing break, on top of my latest fw (with the paraphonic bandpass).


but if you want to compile yourself the fw :

• use stm32cubeide Version: 1.5.1
• compile the release firmware
• in /scripts, edit ./create_object.sh :
  change the OBJCOPY_BIN path according to you configuration
  (that file is from ARM Toolchain)
  i personnaly put it in the script directory, so OBJCOPY_BIN="./arm-none-eabi-objcopy"
  
• in a terminal :
  
  • cd ./scripts
  • ./create_object.sh

the .bin should then be found in the /script folder

A little bump on this topic, as there is an active pull request with this filter.
https://github.com/Ixox/preenfm3/pull/52

(Love it, it's a nice fx)

Hi,

the filters are not designed for good keytracking, sorry for that.

A workaround (maybe) would be to use a multitimbral configuration, then with the vosim algo, you may get the kind of peak sound you're after.
(for thoses algo, you need the latest fw for preenfm3, or the alternative fw for the preenfm2 : https://ixox.fr/forum/index.php?action=dlattach;topic=70017.0;attach=1165 )

compressor presets can wait..

after many tweak, i may have a stable version for the bp filter, it's hard to get more juice of it anyway.
while i'm at it, i tried to add some more compressor preset,
it needed to add a gain parameter to allow much more compression, so there is these 3 : hard, soft, wall
