Hi Ted,

The answer to your query is fairly straightforward. Each track in the sequencer is nothing more than an individual recording facility. You will record onto it, any voice you wish, at anytime, and likewise, be able to change to another voice at anytime. Some tracks are of course, specific to certain functions, and may not be changed to another function.

As such, when sequencing, you would 'lay down' a track at a time, and build one track on top of another. If you don't like any of the voices you've recorded, they can be changed to suit. This way, you progressively build up to a band or orchestra. You can literally, do what you like, and produce what you like. Hope this helps. Good luck Ted.
