Yeah, I have the MPK 49, it's decent, but is a half-breed, to me. Sort of synthy, sort of piano-y. I want the workout and velocity possibilities of a real piano. The Numa seems a no-go, too many very bad reviews.
I've decided to get a clean (minimal controls) electric piano. Am going tomorrow to stores to try to find something I like. Think I need to touch it rather than purchase this online.
My only concerns are that it's 88 keys, has awesome piano feel (requires me to muscle through it on heavy notes, and actually plays soft when I do), that it can work with my computer is turned off for improvising, and of course that it works with Cubase and my new headache (will take a lot to learn!), Sibelius. It would be nice if it has a minimal sequencer built in, so I can sit there for an hour improvising and catch it right in the piano, then listen and bring into my DAW, but that's not absolutely necessary.
I'm going piano hunting tomorrow after wanting a piano my whole life, yay! I need to find my harpoon:) Or rather, pianopoon. Oh nevermind:)
