okay first i used amazingmidi v 1.7 to create a midi file from a wav file. the original wav file had four parts sax., piano, bass and drums. in the conversion the drums are lost and the other three instruments are merged to create a piano midi file. this means all the notes from the three instruments appear and play as piano in BIAB in the melody track. i brought the midi file into BIAB style wizard initally but can simply open it as a midi file too. since asking the question i have managed to move the bass notes over to the soloist track by editing each note`s channel number from 1 (which all the notes are) to 2 and using edit-track move. i can now choose the bass instrument i want. my aim is to remove the sax. and then have a backing track in an original form without using BIAB styles. it looks as if the only problem is going to be replacing the drums as the midi file doesn`t have a fixed tempo.
my question is must i edit each single note`s channel number one by one or can i change them as a block and then transfer them to the solo track

culfy
