Hi all. I recently purchased a keyboard with MIDI. The keyboard has no MIDI connectors, but rather a USB connector. I have a MIDIMAN, but I think its strictly MIDI-->USB, and not the other way around (could be wrong). So anyway, is there any reason to connect the keyboard straight into the USB, instead of routing it through my Firebox (which has a breakout cable with MIDI connectors). If I SHOULD connect through the firebox, how should I do this?
