Thanks Cassp for your prompt response !
yes I use QY700 as source and then I convert the midi sequence already in the patches into a Pattern. When only the tracks are filled with the rights patches/instruments. I wonder if the problem is not related with the midi file format( XG Yamaha compatiable ) or with sending Sysex signal through a midi file ? It could be a configuration matter of Software sequence, Midi file or just a small thing to change within QY700 ?
