Hi lk280king, In fact you have to export left hand on channel 3 and right hand on channel 4 of your midi file. In my case, I use MuseScore. I create a sheet with 4 instruments. I put left hand on the 3rd instrument and I put right hand on the 4th instrument. 1st and 2nd are empty That's work fine. To answer to my question, I've just an answer from casio. It's not possible to add marks Bad luck

Hi, I have converted several midi files into cm2 files. (with smf converter) That works fine. Left hand and right hand are goods. Now I want to learn the added file thanks to lesson feature. But the "Step up lesson" section plays the whole music (i.e. the music is not split into lessons). How can I put mark into my midi file to cut my music into several parts (lessons)? I hope someone knows how to do it. Thank you
