Arbaz,

I am using a Roland G1000, which has 64 voice polyphony, and it is NOT ENOUGH.

Tyros, as well as the previous generation of Yamahas has 128-note polyphony. You may argue that their allocation is worse than Korg's or Roland's or GEM's, but at least they recognized that the previous limit of 64 voices was insufficient for an arranger keyboard. Ditto for Technics.

IMHO, good selection of insertion effects is nice, but should not be necessary on the arranger keyboard, where the primary thrust is on trying to accurately reproduce the acoustic and existing electronic sounds, and those, when sampled well, should sound good when you first turn the instrument on, without the need for additional effects. Perhaps, a synthesizer board with the leading-edge sound synthesis technology should be offered as an add-in board, for those into making new sounds and using them in their performances. But I (and I'd guess, many others in this forum) want to turn my keyboard on and start playing, instead of fiddling with the sounds.

Regards
