preenfm2 and preenfm3 / CC_UNISON_SPREAD & firmware building problem

« Last post by Davidttl on April 17, 2025, 10:23:26 PM »

Hi,
I have a small problem that is bothering me.

CC 14 instead of working only on unison spread it also starts the sequencer. And it is slowly driving me crazy.

case CC_UNISON_DETUNE:
            this->synth->setNewValueFromMidi(timbre, ROW_ENGINE2, ENCODER_ENGINE2_UNISON_DETUNE,
                    ((float)midiEvent.value[1]) * INV64 - 1.0f);
            break;
        case CC_UNISON_SPREAD:
            this->synth->setNewValueFromMidi(timbre, ROW_ENGINE2, ENCODER_ENGINE2_UNISON_SPREAD,
                    (float)midiEvent.value[1] * INV127); 
        case CC_SEQ_START_ALL:
            this->synth->setNewSeqValueFromMidi(timbre, SEQ_VALUE_PLAY_ALL, midiEvent.value[1]);
            break;

And it looks like there is no “break;” before the next case CC_SEQ_START_ALL:
All good, I'll be happy to test the changes for myself, but........

I have a problem to create a .bin file
There is no make in the folder, STM32CubeIDE is unknown to me but I tried. Lost files, folders - ok, SD card settings - not so good, problems with the clock - is it serious?!

So, what's the story with that firmware ?

I tried from the official repo and all I have left is a headache.

What is a trivial way to compile this firmware ?

Thanks

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)

Yeah, kinda sadly quiet here in 2025. Would love to see updates to the editor (which I only realized today works for fm3!)

Thank you Xavier, The link of how to flash the firmware appears to be dead.

Hey,
I totally missed this message, sorry, preenfm1 repo is here
https://github.com/Ixox/preen

You'll get the pre compiled firmware in the "firmware" folder.

Best

preenfm2 and preenfm3 / Re: Tuning filters to fundamental note pitch

« Last post by Toltekradiation on November 14, 2024, 08:48:10 PM »

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 )

preenfm2 and preenfm3 / Tuning filters to fundamental note pitch

« Last post by SpectralClockworks on November 13, 2024, 08:00:52 PM »

Hi fellow preeners,

Is there a trick to getting the filter to tune to the oscillators for 100% keytracking to be in tune? I was trying to recreate some piano patches with complex FM noise as the input and a peak filter tuned to follow the keyboard, but I couldn't get sufficient resolution on the filter cutoff settings to tune to the fundamental (I can get 100% keytracking just fine, but I can't get the filter to be in tune with a standard 400hz reference scale).

Am I missing a trick to make this work?

Thanks!

Sorry for the delay. Where do I find the compressor? (which menu)
