Hello, I've started my music career by composing in regular computer midi sounds, then purchased a Yamaha S03, which is a nice keyboard but now I'm at a level where I need more of a professional workstation.

I need advice from some professionals here.

What would you recommend to buy for around $500-1000? I've been thinking about Korg Triton LE or something similar.

Also, is there a way to buy Korg Triton module ("brain" without the actual workstation)? and then just use midi keyboard to play it? I write all my music on the computer thru a midi connection, so that shouldn't be a problem.

Any help will be much appreciated, thanks for looking.
