PreenFM2 / Re: reinstalling firmware
« Last post by Xavier on February 19, 2020, 02:53:38 AM »

Upgrade firmware page is here:
Easiest way is to do (1) to upload the *.bin files in /pfm2.
Then (2) to flash.
Yes it's better to unmount flash disk from you computer before "exit" on the preenfm2 to be sure the file copy is finished.

When using zip file, you must not copy "build" directory.
Copy *.bin file in /pfm2/ folder.

Hello.. My answer will not help you more, cause I'm having troubles too, installing version 2.11..
I unzipped the zip file to pfm2.. I also have the "build" subfolder, ok ok..
But then what does "unmount before exit" ? Means that I must, on my computer,  click on "unmount drive safely" or whatever it is in English (Extraire le lecteur en toute sécurité)..
Ok, that's what I have done..
And then exit, and then I press the [op] button, and it says "no /pfm2/ directory"..

My drive is as follow:


Thanx to anyone who will take the time to help..
Have a good evening..
PreenFM2 / reinstalling firmware
« Last post by dzenat on February 18, 2020, 11:40:44 AM »
hi again,

i think I might have messed up some the usb drive. I tried to upgrade firmware to 2.11 by copying the 2.11 zip file to the usb drive and unzipping it. It then creates a build folder. I put all the files into the drive and plug in the usb & start the preenfm up. now i get a blank screen. What's going on? Should I reinstall the firmware again? What are the steps I should do to reinstall the firmware?

finally got time to fix this. it's working now, well at least after 2 power up, I get a normal screen. Before reporting on sound and all I realized that when i removed the sides of case, the preenfm powers up properly. There might be something wrong with the usb drive as well. I've got a blue one. At things wriggling it helps. Otherwise, I check soldering jonts and psuh the graphic board deeper, so maybe that help too.

Seems like there's an update on the firmware. I might try to get a new usb to test and update the firmware.

Will try testing sound soon.

is anyone else using this firmware who can confirm that the synced speeds for the LFO seem to have disappeared?

Ok, it seems to be working now.

What i did was;

Connected standard MIDI (in+out) from soundcard to Preen2fm
Used DAW version of the editor.
Turned off MIDI for my soundcard in Cubase
Turned on the same MIDI in the VST editor itself
Playing midi track using USB (called "Preen2FM Editor Out").

There's a big difference using standard MIDI with the editor.. the sound playing actually stops for a short time when you edit variables in the editor. With USB the sound never stops when you edit something, it continues and gets garbled as you e.g move the envelope, its easy to understand that notes gets stuck because it just can't keep up with what's going on.

Hopefully its of some help to someone having the same issue. I usually like to have a sequence on repeat when i make patches for synths so that i can hear the changes in sound in real-time (and without tediously having to play manually on the keyboard). I guess this is part of the issue i had perhaps, having sound playing + editing at the same time, with USB this does not seem possible due to how its processing the sound.

Thanks for the reply.

I use the stand alone version of the editor, so i don't think its a midi loop?

MIDI Thru is disabled.

Got it working in my DAW, same thing, whenever i touch e.g envelopes stuck tones occur.. "reset" in Cubase is useful, this does work and resets the sound to normal. but tiresome since there is not keyboard shortcut, i have to use this reset every 2-5 seconds when editing a sound.

I've tried two different USB cables. Tried different ports on my PC.

i did that. but still the same, as soon i load some preset, tweak it and want to load new preset i cant do that.
and first loaded preset stays in synth till restart it.
maybe there is some special way how to exit preset tweaking mode ?
in meantime i can press 5 left side buttons and i can hear preset only that way. but i cant load it

Stuck notes : double check midi loops from the daw. And disable midi thru on the preen.
To be able to select the pfm2 midi port from the vst,  « preenfm mk2 » midi port must not be enable by the daw.
