I have been reading these posts and I just got off the phone with the product manager at Yamaha and asked the question regarding how many dsp's on the 1500. The answer is.....the same as the PSR3000, plus......the polyphony on the PSR1500 is 96 which is completely dynamically allocated, which means you don't have some for the styles and some for the panel voices. All the polyphony is available for the whole keybaord.
Another addition over the PSR2100 for those who love playing drawbar organ sounds is the addition of 1 extra drawbar over the 2100 so there are now 9 drawbars.
If you want to get a PSR1500 I have several in stock and will do my best to beat any price you might have been quoted!Please Contact me!
