I popped by to PS and had a quick try on the CP-1. Not too much time since kids in restaurant waiting for lunch (I had permission from wife to sneak out for a few minutes).
Took a bit of time to hook it up since the audio cables were connected to the CP33 above it - and they don't have enough cables (!).
First impression was the wooden keys. It's slightly off white. Quick playing immediately brought reminiscence of the Roland V-piano. Feels and look very much like alike.
Knobs in front are touch sensitive - pressing down reveals the parameter value it controls. Easy to get the sound you want - mainly piano/keyboard sounds. Sorry, no strings and other sounds. No organ sounds either. And of course, no layering.
Piano, for the first time in Yamaha, didn't have the irritating tinkling sound in the high register. They did it the right way finally. Hopefully the SCM sounds will slowly replace all existing AWM piano patches. Changing the hammers from soft to hard gives very distinctive changes in tone - which is a nice thing for customisation. I can do a lot with just one patch of piano sound (the first patch) and adjusting just the hammers and EQ alone. It can create sufficient different tones for different types of playing from classical to jazz and pop. Love it!
DX7 sounds - nice thing to have indeed. One caveat. It's SCM and not FM - hence you cannot program it like you would for an FM sound. I love DX7 e-piano sounds, but I love a particular tine piano of which I would need to tweak. I couldn't do it to get the exact tone I wanted because...I can't program it! All I could do is standard detune/EQ stuff, which is just skin deep. I wonder how difficult it would be for Yamaha to put in an FM generator just for that. I mean, the FM generator is old technology - I'm sure by now it wouldn't be larger than a small chip sitting inside somewhere.
Can't hear clearly pedal resonances. The Korg SV1 and Roland V-piano are more obvious. It may be the speakers.
So...while I love the fact I can tweak piano sounds (and I do love the piano sounds - finally!), I'm slightly disappointed I cannot tweak the DX7 sounds enough.
And of course, the presence of a pitch bend makes me wonder why they even put there in the first place.
Conclusion - this is really for those who love and play the piano. That's where it ends. Would I pay $7000+ for this keyboard? Probably not. I would love to try out the CP-5 and CP-50, which I believe will have a larger market than this unit.
