Eric,
I felt the same way when I played the PSR9000. The PRO model really seems to react different - must be the expressiveness of the keypad. It feels just as good as the keys on the "76 key" Triton.(which I believe it IS!)
I know many of you will not believe me, but I actually bought one of these beasts - even though I will miss the speakers terribly. I'm taking it out tonight for the first time. I only spent a few moments with it so far, and I don't have any custom registrations written yet, so....... it MAY be a challenge. I always take a new instrument out in the field as soon as possible, because it really makes me "learn the ropes" faster. There's nothing like "FEAR" to make you think more creatively! (and FASTER)
I tried the PC input with my laptop and the GM sequences work right away, without any fuss - there are a few files that sound a little strange to me, but I wouldn't say bad.
I'm using the outboard harmonizer too, because I haven't been able to figure out if the ONboard one can work the way I need it to. I need to trigger the harmonies with the right hand sounds, and have them sustain through the chord changes - not just react to the note values.
So for tonight, I'll play what I can, and learn as i go - wish me luck. It's gonna be weird without the speakers. What am I THINKING???????
