Hi Steve, I should clarify what I mean by "parts". What I should've said was that I play say four notes in via the keyboard. What I need to do is isolate the notes out so I can put them on separate tracks to save out as midi files - or as one midi file with the proper data; from there I should be able to import it into Lime so that it'll come out as if I did it all separately from the recording facility in Lime. I know that I have to prepare the piece I'm writing to accept this data correctly. Does that help you?

By using the Sonar Interpolate feature, in the first field, isolate an area of notes and in the following field simply change the midi channel. all the isolated notes in that area will now be on the selected midi channel. Just keep repeating this process, until the bass guitar, Sax, strings and piccolo all have midi channels of their very own. Steve W
