Title: Preenfm 3 USB Midi unavailable
Post by: doctorsolberg on October 10, 2021, 01:25:50 PM

Hello!
Have a problem with PFM3. Connecting it to the USB powers device, but it's not sowing as midi device in the system. Other synths works well with the same PC. USB Midi in/out is enabled in PFM settings.
Where at least to start looking for the solution?

Hi,

Some users had a problem when powering from the DCin 9v.
Then if you plug the USB you need at least to wire the USB GND on the pfm3 PCB.

On recent PCB it's now always wired, but on some previous versions, it wasn't.
Is it your case ?

What version of the firmware and bootloader are you on? There were some issues with usbmidi in the early days of pfm3...

I assume you are on windows? How do you test midi? What DAW?
