I had a 2100 briefly, for demoing, and I already had two PSR-2000's for gigging (I was working a lot back then). I didn't find enough differences to move up, much like now, with the not moving from Tyros4 to Tyros5. Also, like the 2K, the 2100 still only had 8 drawbars for the organ model but it did have a slightly better piano sound, if I remember correctly.
I sold both my 2K's, and I went directly to two PSR-3000's, and I have to say, they were pretty awesome keyboards...and Yamaha finally got the organ modelling correct (9 drawbars, and much better effects).
Only for the lure of the PSR-S910's terrific SA Voices and on-board Audio Recording, I would have stayed longer with the 3000's.
I realized the shortcomings of Yamaha's VH, and I worked around them okay, and even the VH2 on my Tyros4 is still not up to TC Helicon standards, but, if used wisely and sparingly, it does the trick quite well. I find a many singer/players, of all brands, use VH too much (just because it's there doesn't mean it has to be used in almost every tune), and sounding like a barbershop quartet or a barely passable version of the Bee Gees or Manhattan Transfer gets old really quick to this listener, even when it's done on a TC Helicon VH.
I really like Michel's presentations, especially his early ones...makes us remember how good these older keyboards were in the right hands.
Thanks Fran.
Ian
