I have posted a few threads about my problem with a USB MIDI interface and my Roland FP-8 digital piano.

First I had a XP MIDI Mate by Audiotrak (www.audiotrak.de). When I used it with the FP-8, the interface and computer (running Mac OS 10.2.6) did not respond to all the notes I played, and notes "hung" even though I'd stopped playing.

I've tried the set up with another computer running windows XP and another MIDI app, and had the same problem. I've also connect the FP-8 directly to a MIDI module (roland sound canvas) and it worked perfectly, so the problem is not the MIDI out stream on the FP-8.

I went to the music store where I bought it, and there they plugged it in using another (non Roland) keyboard and it worked flawelessly. Well I got to replace the XP MIDI mate with a RoMI/O by ESI (www.esi-pro.com), also a USB interface. (I think audiotrak and esi are the same company since they have the same tech support.) Anyways, I got home, plugged it in... the exact same problem as with the XP MIDI Mate.

I think that the problem is a hardware bug, that causes compatability issues with the Roland FP-8...but I'm no expert. I'm pretty sure it's not a Mac OS X problem.

I really need my piano for Cubase, and I don't have time for this crap!...pardon... So, my question now is: Has anyone used a USB MIDI interface with a Roland FP-8 (or a close relative to the FP-8), and if so what interface? Has anyone tried any of M-audios cheap usb MIDI interfaces, such as the midisport 1x1, and if so do they work well with Roland Digital Pianos?

Thanks for your reply!
