Scott,

Unfortunately, this board has some limitations. You cannot alter styles in any way, except by choosing variation A or B (B always being more busy)plus you only have one intro and one ending.

You can turn the channels on and off in a MIDI file. There are 5 buttons in the sequencer section that control this feature. You cannot re-assign voices, except for what they call the 'song melody voice'. So whatever happens to be on track 2 can be reassigned. This is where the low price tag takes its toll, but hey, what do you want for pocket change I'm still amazed at what they DO include on this board.

As far as registrations go...you can save up to 16 presets (eight banks of 2 ea.) You can save Style settings, Voice settings, Effect settings, Arp settings, Harmony settings...along with transpose, pitch bend range, and knob assign.

Hope I've answered your questions adequately.

Best regards,
Tim
