Any idea of how to split a single track in to several tracks/channels?

I have some strings that have pitch bend occurring between notes.  The problem is, some notes are playing with the next note's pitch bend for a split second while the sound is stopping, and it sounds awful.

I'd like to try splitting the track so every other note is played on alternating channels, that way each note has time to properly finish without being distorted by the next.  Naturally, it would have to take the appropriate other commands along for the ride.

This is one of the shortest songs in the soundtrack, yet is giving me the most trouble.  Spent several hours today manually removing tons of extra pitch bends at the end of each and every note.  It now sounds almost normal, except for these random locations where the notes are still going and getting bent from the next note.
