The only small thing about this keybord is it's size. Tone and playability is huge here!
Let's start from the key size as it's the very first thing i got my hands on. Being small doesn't necessarily mean that you are limited. In fact i found out that it can become a benefit because you can reach keys that you normally can't in a normal size keyboard. The trick here is to adapt your musical style to the specific instrument and that's where the magic starts. I found out that it can be a bit painful for your pinky if you play a lot with it but it can also be the case that i am not a keyboard player and my hands are not used to this fingering positions.
The tone of the instrument is great especially if you decide to hook it on a pair of nearfield monitors for practice, like i did. All the voices are great and usable except the Toy-Piano which i didn't find appealing at all. I can't imagine how this sound can fit in any mix, but that's just me. The built-in speakers are also very impressive in terms of sound quality. The stereo tremolo when combined with the Rhodes sounds is enjoyable and eargasmic. All effects are very responsive and most important easy to tweak while playing. The interface is super simple and a no-brainer, just the way it should be.
The portability is there (6xAA batteries) but i found out that if you play in full volume the batteries will get drained after 6-7 hours or maybe less. So i think that it's not safe to jam more than one time with the same batteries.
Overall the CP is a great instrument for the studio and for your couch or bed. Being so lightweight and so rich in sounds makes it a perfect tool for practice during a lazy afternoon ar even your work-break time. No joke, you can easily fit this thing under your screen/behind your keyboard. :D
