Ok, this might be another you cant un-bake a cake thing, but with MIDI being a digital thing it may be different,

I have a fair few midi tracks some have each instrument in its own track so I can change the instrument/overall mix etc, however some havebeen "MIDI Mixed" into one, so what I have is what I got.

is there any way of seperating these various midi parts? so I can then re-mix it to suit purpous, or not.

Im still relativly new to midi, but getting there.

Oh the sofware I hae access to is Sibelius, Cubase SX, and SX4

If your midi file has each instrument playing a different sound, then you don't have a problem at all - MIDI has a type 0 or type 1 format. In one, all midi channels are merged, in the other they are separate.

Sibelius is a great score writer, but it is NOT a sequencer, so open Cubase. Left click on the merged track, it goes black. Then got to the menu bar, select MIDI, go down to 'disolve part'. When you select it you get a choice of tracks or pitches - you DON'T want pitches. This will extract out the one merged track into however many real ones there are. Warning - the merged track is still there and will try to play - so once you've made sure the new ones are really there, delete or mute it.

That's it. Once you have done this, you are away!

BRILLIANT

Many thanks, make my life easier.
