I did it a few years ago and it was a very rewarding experience. I created all the synth patches from scratch, wrote all of it, played everything, recorded, & mixed it. I used some drum modules for generating some percussion sounds, but still played the parts 'live' with a Kat controller (or on a midi keyboard). No drum machine parts and no looping. No samples except a brief piano bit on one track. I had it mastered by a good pro mastering house and was glad I did.

I enjoyed the process so much that I'm doing it again right now. But this time I am considering having a little help from other musicians, maybe something unusual like a cymbalom or some North African wind instruments.
