Just read this on the Gearspace board regarding PreSonus mixers and MPC compatibility:
Just in case anyone was wondering if Presonus studiolive mixers will work with the new update (nope, quote from presonus forum)
“Yeah, that’s not going to work.
The Series 3 hardware isn’t USB Class Compliant, only the drivers on Windows / Mac are.
Series 3 is a 64x64 I/O device, which already exceeds their I/O spec stated in the video (32x32).
This is the same reason why Series 3 doesn’t work on Linux natively. It needs a driver.
Series 3 works on iPad because Apple writes the driver for their ecosystem, which already complies based on MacOS. Now, it’s up to the App’s to support the channel count (N-Track is the only one I think).“
