Please don't take this the wrong way but, it seems to me everyone is looking for the definitive organ (usually 'B3', although that could represent any one of over 100 million different registrations) but if you listen to most of the music posted (not counting mine), hardly any contains any organ parts. Is this similar to the eternal quest (by synth players of all stripes) for the 'ultimate' piano, although most of the ones most critical, suck at playing acoustic piano.

I think 90% of the organ voices available on today's TOTL synths, including arrangers, are more than adequate when used in an ensemble setting. Why aren't we more critical of brass and strings and bass? They're much more prevalent in the average arranger style than piano. The truth is, the reason most organ parts sound 'less than authentic' has less to do with the quality of the Leslie simulation than the fact that most non-organ players don't use an expression pedal. I've heard any number of leslie sims on a variety of synths, hardware and software, including my own Nord C1, and I defy any of you to positively (as in, your life depended on it) identify which was a real Leslie and which was a sim. I'm not saying that a certain hardware simulator may not sound better than an on-board one (with SOME registrations), I'm just saying, before you lay out all that 'moolah' expecting a little black box to turn you into the next Jimmy, or Joey, or Klaus, or Claudia, remember to use your ears rather than the hype to decide (then send half of your savings to me as an 'advice fee'.
