Eric,
To be honest - I wish the pro WAS only 61 keys. I like having low "C" as the bottom of the keyboard, and I'd rather have a shorter piece to carry. Oh well - the price to pay for that great feel and expressive action, I guess. I have a party today, and I am going to use the built in mic pre amp. It still doesn't act like I want, but hey! Maybe I'll find a workaround.
After playing it last night at work, and then a little at home - I really am spoiled by the key action. So far - NONE of the arrangers feel this good. The closest was the X1, so maybe the SD1 will have a good, solid feel too. I sure hope I can get the harmonizer to do what I need - I want to keep this keyboard..... if I can. Any ideas, users????????? Help me sustain the harmonies with the RIGHT hand. ( even when the keys are lifted)
