Howdy _Stf_, I got this keyboard for Christmas and I'm currently battling through the same process as you. How did you split the piano part of the midi into left and right parts? I went to an online shop and bought what I think is a professional midi and it only had one piano part, I cloned it but it is still just playin gboth hands together, is there something else I'm meant to do? On to your point about adding a mark, I'm not sure how but I would add it at an even split in the tempo or ever 4 bars of music. Something like that so it's only parcels of the song at once. I'm having the same issue though as I can't get it to split into lessons and it plays the whole song with both hands.
