PIANO YAMAHA CSP_170 [Smart Piano] midi conversion then upload PROBLEM!!

Yes! please I have a big problem! sir/madam with my csp-170 yamaha piano called smart piano. This piano need the midi which should bes created with two separated channels (1 and 2) treble and bass separately in order to upload this MIDI file to this clavinova CSP-170 digital piano in order to see all notes on properly location on music lines treble and bass. Look on my score on the TAB (samsung) {screenshot's] this score coming from midi conversion but notes are in various location because seem to me was not converted properly to two separated channels 1 and 2 treble and bass, is why all mixed together and created holy cow crap and mass look please event no chords on bass clef. So can you convert in right way?

Secondly have no clue why one guy (tech supp from this MuseScore online) he sent me my problem here, instead to ask the engineering team who designed this "MuseScore" database website and software. The people can not I think resolve this problem, because public people/customers , nor music enthusiast, artis did NOT designed  this MuseScore" so how they can help me with RIGHT CONVERSION from score to MIDI in two separate channel (treble and bass clef]. Or maybe someone here is the music-einstein genius to tell me how do that? or which software from other store I need to have or purchase? in order to convert specifically as you see the yamaha boosted on my second screenshot. They says must be specifically! so this musescore can do that?  Many Thanks! and Happy New Year 2004 to anyone here and there!
