Update: I got MIDI to work, after a bit of finagling and, er, manual reading. The default setting for the internal synth is to respond only on channel 16. Once I got that working, everything operated perfectly. I suppose they chose channel 16 to avoid conflict with other synths in the MIDI chain.

What a sweet piece of kit!

Yes, you can. Use the “transpose” mode. The gender knob will work on your voice. It does a lot of processing, though, and samples at 36khz (as opposed to CD-standard 44.1) so it will sound effected even in the dry state.

I have found that a mix of the pitch and gender knobs create a very realistic low voice.
