E570 question?

I read the manual a few times, and it still isn't clear to me:

what settings are saved/stored/written for each MIDI preset?

Everything except what the knobs control. If you wanted midi progamming for the eq/gain etc you would have to find a 580.

Midi patches store the channel, eq switches (contour, mid edge, bright etc), gain boost switches, preamp defeat, noise gate, and modern/classic mode.

Thanks!
