Ian,
The RS-70 or probably any synth for that matter isn't going to work for anyone who likes a "style" backing --considering the RS is just that "a synth"

I'm not comparing the RS to the entire voice set of the 3000. I'm not comparing the RS's voices to Yammies sweet, cool, live, and mega voices.... Those voices shine all on their own I'm talking about the RS-70's 64mb sound set as a whole compared to the panel voices of the 3000 with disregard to any "special" voices.

What did you play the RS through as well? I'm using a set of "Berhingers" (Former Roland Micro Monitors-same speakers with the Berhinger name).

I'll throw some demos together and email them to you (since you've already played the RS, and have an idea of what it sounds like).
