Few people know LESS about MIDI than me, lol, but I remember reading something here a long time ago about how the voices are assigned to the MIDI channels on this keyboard. Now, this is by memory from years ago, and I have never tried this (I virtually never use MIDI), so I cannot say for sure if this is correct, but maybe it will give you a starting point.
I remember reading that Channels 1-8 are for the melody tracks in the onboard sequencer, with each track's main and dual voice getting their own channel. I don't know if it channel 1 = track 1 main, channel 2 - track 1 dual, channel 3 = track 2 main, channel 4 = track 2 dual and so on -- OR -- channel 1 = track 1 main, channel 2 = track 2 main, channel 3 = track 3 main, channel 4 = track 4 main, channel 5 = track 5 main, channel 6 = track 1 dual, channel 7= track 2 dual, channel 8 = track 3 dual. In any case, since there are 5 melody tracks, each with main and dual voices, making a total of 10 parts to the melody tracks, but only 8 channels that are used for the melody tracks, two of the parts do not get sent. But again, I'm not 100% sure of the structure.
And then, I believe Channels 9-16 are for the different parts of the auto accompaniment, like the drums, bass, and pads. Unfortunately, again, I am not sure of the structure -- perhaps they are roughly in the order that those parts are labeled on the accompaniment section on/off buttons, but that is just a guess. Also, while there are six different accompaniment parts labeled on the buttons on the control panel, I believe some of those parts are spread among two MIDI channels, therefore using all 8 channels from channel 9 to 16.
I do not know if the split voice gets sent or not. As it cannot be recorded in a multi-track sequencer recording, my guess is that it does not.
