Hello!
Could someone provide steps to upgrade this for me?  I have upgraded my PreenFM2 to 2.10 o but do not know how to adjust the source code to add these new filters.  Is anyone able to "dumb down" the steps for someone like me?  I would appreciate it!  :)

Hi,
You don't have to compile the firmware.
Download the latest firmware attached to Toltekradiation's message just above.
Easiest way to upgrade is is to put in on your USB key and to flash from it. Step 1&2 here : http://ixox.fr/preenfm2/manual/upgrade-firmware/

PreenFM2 / fm electric piano and fm slap bass
« Last post by maki on August 24, 2019, 10:40:35 AM »
hello,
can somebody make a short mp3 demo of Preenfm patches similar to dx electric piano and dx slap bass and post a link here or on youtube? I dont expect dx7 but I found no Preenfm demo on those typical and highly wanted fm patches. Just to hear what Preenfm is capable of in those areas. Thanks

I get lost at "add the bin..."

  • To compile the firmware, you'll need arm-gcc version 4.7
  • Add the bin directory to your PATH, and run 'make', you'll get the list of the available targets.
  • 'make pfm' builds the firmware.
  • Then put your preenfm2 in bootloader mode. Look at DFU part 4.
  • 'make installdfu' flash the firmware on the preenfm2 using the DFU protocol.
  • Once it's done, unplug the power cable and plug it back.

Take care,
Kyle

It now works perfectly, it was indeed a faulty USB key! Thank you all for your work, it is awesome. Played a few presets on it a few minutes ago with a nice plate reverb :)

@megalomidiac : maybe the name is too long if you flash from the the USB key.
Rename it to 8 charaters + ".bin" and try again.

That was the next thing, I wanted to test, but no luck.
I will check tomorrow, if the USB key is bad and will report, thank you!

@kaosbeat : If you flash this firmware on a eurorack you'll lose the eurorack specific features.

@Toltekradiation : FYI the eurorack version is in the "adcIn" git branch : https://github.com/Ixox/preenfm2/tree/adcIn

@megalomidiac : maybe the name is too long if you flash from the the USB key.
Rename it to 8 charaters + ".bin" and try again.

I'll eventually merge this modification into the main branch, add the filters in the editor and release both main and Eurorack version. I just cannot say when  because i have no idea ;)

hi,
@kaosbeat : it should work as i made changes on the last official sources.
@kyoto: i think that the new filters should be merged first in the master : the editor is for the master version.
 you should consider what i've done so far as a work in progress, i'm still playing with it and it's not bug free. Maybe later, Xavier might want to merge some of the fx when they are stable..
anyway, here is a new version with a bug correction in the hp2 :) + some changes : i removed the swap fx which was too harsh for my taste ; i'm playing now with the idea of bit mangling in 2 new fx texture1 & 2, well, i might as well have named it distortion33 & 68  ;D.
Another change in this version is the filters lp2 & hp2 offset changed to match the original cutoff of lp & hp : in fact, they now sound quite the same, they are maybe just a bit smoother, so lp2&hp2 might replace lp&hp if you guys think it's worth..
@Megalomidiac : that's weird as i also use the preenF405 board with bootloader 1.11 without problem, don't know what can be the cause. :-\
