preenfm2 and preenfm3 / Re: Preen editor in browser
« Last post by Toltekradiation on April 03, 2026, 10:10:01 PM »
Hello,

Here is a firmware update that simplifies editing the PFM3's envelope curves via the web application.
Filter 2 is also now editable.

The stereo bandpass filter has also been improved: this version features 3 poles, providing a more focused response.

I removed the experiments with Karplus-Strong algorithm and the resonator from the code, which were not really useful in my opinion.

thanks ! :)

Next challenge is to add the operator enveloppe curves selector, it will need a firmware adaptation as well, but it may be cool, for a faster edit!

Hi,
there was some bugs, like the arp clock setted to Ext by the editor, for some reason, which was maybe the cause of the issue you describe.
Hopefully this bug is fixed :)

There is now a new feature : Mutations. The idea is to interpolate between two patch to get new sounds. It gives some fun results so far.

This is really cool Toltek!

I am having one problem: Is there some default/critical setting that I am missing? I can send patches to my preenfm3 and the settings on the preen match what I have in the browser. But the patch is making no sound. I have the OP volume up, I made sure the patch is not using too many voices to go over the max. Any ideas?

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  :D.

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.

preenfm2 and preenfm3 / PreenFM3 starring on weeklybeats

Hi all, I know this forum is not super active (and neither am I), but I just wanted to drop a note that the news of PreenFM being discontinued inspired me to submit something made with the PreenFM3 to weekly beats. If you're interested, find it here: https://weeklybeats.com/wahsp/music/supreen

it basically replaces the firmware on your Preen FM
Ok thanks for confirming that. Presumably that's an 'unofficial' extension of the current firmware. Should I back up all my patches before installing - I mean, will it overwrite everything?

I just tried it. You keep your preset banks and so on, if that is what you worry about.
