"Serious synth guys probably need midi connections".
How insulting is that to "serious", and not so serious arranger players
I think it was a very poor decision. If it's competition with their current products, then it shouldn't matter if the midi is there or not. Even without the midi the YPG/625 already (since it now has balanced hammer action) will compete with the P60/70, and even the P140 series. Personally I think that's a very standard and basic feature that wouldn't have hurt them in any way to add.
I'll probably try talking the guy into getting the M-Audio ProKeys88. It's one hell of a controller with a few sounds as an added bonus. Check out the specs. It's price range is that of the Yamaha P60/70
