PreenFM2 / Re: Cannot read or write to USB storage
« Last post by Xavier on September 04, 2019, 03:13:12 PM »
Hi Nick,

That really sounds like a problem with your USB stick.

Try to format it again in fat32.
Then unzip this file.
https://github.com/Ixox/preenfm2/releases/download/2.08/pfm2_usb.zip
on it.
You should have everything in a /pfm2/ folder.

Optional : add in the /pfm2/ folder the 2.10 binary for Eurorack :
https://github.com/Ixox/preenfm2/releases/tag/2.10
So that you can easily flash it if needed.

PreenFM2 / Cannot read or write to USB storage
« Last post by nmveld on September 04, 2019, 09:31:57 AM »
Hi All,

I just finished building the euro version of the PreenFM2. Everything works fine except for reading and writing to the USB storage. I copied the firmware from the VanDaal product page to the FAT32 Usb Stick that is included in the kit. There is a communication connection between the module and the USB because it only boots when the USB is in the module, but strange enough it doesn't show any saved patches and it doesn't let me save (the module even freezes when I try to save).

Has anyone else encountered a similar problem? I also tried a second Usb Stick but it has the same problem.

Cheers,

Nick

@Toltekradiation I understand there is a limitation in processing power... btw. you used the overclocked version (210o), but maybe the "regular" version is a bit less demanding? (just an idea)

@baxgas, sorry for the messy project handling :-[. Yes, that's because i added the new filters before distortions..
the processor is now a bit more busy than it was, i fear. i will now try to optimize my code more.

@Toltekradiation Thanks, I'm really eagerly waiting to hear and test them! :-)

One thing I noted is that when I save the patches with the Filters, in the new version they are messed up, probably because of the numbered positions of the algorithms, and that they change eg. there are more filters before the Distortions?

Also, with the new OS, the parameter changes seem much more sluggish, eg. I have 4 Channels sequenced and I try to change a paramter and it increments only a few steps then stops, also the Inst change is much slower, with a blink of the LCD. Maybe these are already too much for the processor to handle? :-(

Can the filename of the bins be renamed so the PreenFm2 truncation of the characters is a bit more informative?

well, it seems i can't help trying things :), and i find those filters really useful :

and here is the version with volume compensation fix for the SVF filters :D.
