The PA1x voices I feel are the most realistic sounding on a arranger ( my opinion) They will use up to 2 oscillators when needed but, the single osc(wave) is mostly used.

either or I still haven't lost notes on the Korg, or maybe I have but the way they do it I don't notice.

When I had drop outs on the SD1, you would hear it!!!

A friend of mine just bought my Tyros, don't get me wrong, I'll probably buy the Tyros 2, but right now I'm leaning toward the G70,
I think mostly because alot of people don't like it, makes me want to prove them wrong,
