ChuckU, I don't understand your last comment, "So if you're not relying on the 1010 for sounds, then no, you don't need a separate midi interface."
How would whether it had an onboard synth or not affect whether you would need a seperate MIDI interface or not?
The Delta has a MIDI interface. You only need a separate one if you need or want more than one MIDI In or Out port, regardless of the fact that it has no on-board synth sounds.
