I have the PCR-300 and all the controls work fine, it appears as 3 midi ports in Qjackctl and Patchage and you can control what messages (CC, Notes, etc) are sent through which midi port on the keyboard itself. All the buttons can be tweaked a lot and by default most of the controls are disabled in the keyboard (ie. pads) but there are a lot of control presets.

Worked perfectly out of the box for me.

Cheers,
Llewellyn

I have just bought a Roland Edirol PCR-500 on ebay. The keyboard and
pitch bend lever work fine out of the box in Ubuntu Linux (when you plug
in the usb cable it just comes as an alsa midi device). Not sure yet
about the other controls - knobs, sliders and pads.

Buy in thinkgeek.com a Korg Nano Digital Music Controllers (http://www.thinkgeek.com/electronics/musical-instruments/af36/) and make it available for Linux, and make MIDI programming like I make in my several MIDI devices. I have no experience in USB MIDI devices and I want to ask if I can spend with no doubt the 50$ that costs.
