I used this hack to get my PCR M30 working on Windows 10, after finding this page: ... es_drivers

...that says it isn't supported beyond Windows 8.

However, I then happened upon this page: ... river-Mode

...that explains how to change the settings of the PCR M30 so that it doesn't need a driver by changing the driver type from "orG" (Original) to "GEn" (Generic).

I don't know if there are similar instructions for other units but hopefully this might help someone.

Hi Sonichouse, welcome to the forum and thank you for making a helpful suggestion.

Many Roland / Edirol USB devices can use either the generic USB driver or the ‘original’ driver mode. Generic will work in most cases, but the original driver will usually provide improved performance or function. In the case of UM-550\880 midi interfaces, original mode allows the use of:
FPT = Fast Processing Technology of MIDI Transmission: This optimizes MIDI data processing by making efficient use of the USB bandwidth according to the amount of MIDI data being transferred.

So if using generic mode, you have to check in the manual to see what you may be losing. It is, at the very least, a reliable fallback, so very good to be reminded that it is there.
