Johnny, that B is likely your B, or concert A, yes? We should be able to solve that one with a discussion about power (and possibly RFI).

I had an Edirol SD-80. It is made by Roland and is a MIDI synth. It does not handle audio.

I thought the SD-80 was an excellent unit. It was the first unit I connected via digital (using SP/DIF). In testing I quickly decided the digital connection sounded 'cleaner' than the analog TRS cables.
