Number of musicians is irrelevant.
What is important is how you are comforatable with a sequencer's workflow and interface.
Go to the bookstore (I have yet to see and Barnes&Noble or Borders that doesn't have book on ALL the major sequencers including Logic and ProTools). Grab a cuppa java in the cafe and READ READ READ until you see something that clicks for you!
(and go to a music store that has them and will let you play with them before buying if you can..)
