John,
I'm reeeeealy trying to change my wicked ways as far as making changes at whim. I really doubt that I will play another "naked" (speakerless) keyboard though. It's become such a part of my routine that I would miss too much. I wish you all the best with your new SD1's, but I have a problem buying a new model with an old Ensonig name anyway! I hated thje SD1!
Seriously - if I ever needed to take another route - the 9kpro has been my dream machine since I got it. The harmonizer issue is only important in terms of portability. As long as I have to compromise that issue - I will play smaller lighter models till someone gets it right. I have high hopes for the PSR2000. I will need to use my laptop also for midi files, but hey - at least it's light!
