preenfm2 and preenfm3 / Re: Preenfm3 bank & midi list
« Last post by Davidttl on May 05, 2025, 11:22:51 PM »
Hi,
thanks for the kind words, I appreciate it.
 
The midiCC/NRPM list or studying the algorithms (only algos 11-28 overlap with DX7) helped me a lot, so I wanted to share this.
I further consider myself a newbie when it comes to FM. I appreciate Preenfm3 more and more. It's really a unique concept that has been developed all these years. I'm very glad that I had the opportunity to acquire it and something makes me think that I'm going to assemble myself a pfm2 as a spare.

Back to the topic -
I think I got too excited and included this sound bank too quickly.
When selecting some presets (the lfo ones), there are some artifacts. As if the envelopes or modulations are not restarting. I need to take a closer look at this. Is it a change from mono to poly or maybe any of the sources in the matrix. Anyway this behavior precludes changing presets while playing and I'm used to (if you can) the approach Elektron/Renoise offer. And improve gain staging between presets...

Also, thanks for the updated Midi CC list; very helpful!

preenfm2 and preenfm3 / Preenfm3 bank & midi list
« Last post by Davidttl on April 27, 2025, 08:30:09 PM »
Hi,

I assembled the Preenfm3 two years ago, and it was my first experience with hardware FM. As I prepared myself tables with CC values, NRPN (documentation for the preen is its Achilles' heel) and a general template it began to open up for me.

Sound bank - you won't find ‘classic’ FM sounds here. No bells and whistles (pun intended). I tried to step out of DX7/pads/pianos comfort zone a bit. There are some decent (IMHO) Kick presets .Some bass, leads, drones. A few presets made for a joke, because why not. I don't play keyboards, I use sequencers. This is made mostly (except for the drones) for fast 1/16 & 4/4 kick & offbeat hh paterns. Added some overview info, sometimes it's worth playing with env, lfo, IM, find a good octave...

In attachments - MidiCC list, NRPN tables (my audio workstation is without internet and I won't keep searching github or doing math equations to find what LSB value I need), value template, .bnk bank.
Have fun, maybe some preset will suit someone.

preenfm2 and preenfm3 / Re: CC_UNISON_SPREAD & firmware building problem

Hi,

thank you for your quick response.

I tried this method, but I still need the .elf file (because the bootloader's .bin is in the repo and you need both files).
In my case, the Problem Exists Between Keyboard And Chair and this is not a joke as I lack experience with C/C++.

Slowly, maybe on the third or sometime next time (two are already behind me), I'll manage to set up the master repo that I'll have the .bin files every time, without 2-70 errors and then I'll just start some fixes/downgrades.
Thanks again.

edit: small update: still nothing. A little closer, but I'm not giving up. It seems that I threw myself in the deep end thinking that it will be something as easy as AVR and Atmega :)

I'll try to upload a preset bank in the next few days, as I'm working on a template bank. FM synthesis has powerful capabilities, just setting it all up when you have really a lot of options (Preenfm3 is king here) takes a lot of time.

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

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.

(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.
