The best-feeling, most pure piano controller there is.
I bought this sight unseen, as I couldn't imagine any dealer I'd have access to would ever have one. So I was a little nervous when it arrived - not quite buyer's remorse, but worried that I might. Within five minutes, all I could think was "I am going to spend SO many hours sitting in front of this thing."
The feel of the keys is the best I've ever experienced in a digital piano. Real wooden, weighted keys! And _fast_, too. It looks great, minimalist and refined. Not full of knobs and faders, simply as "pure" as a piano controller could possibly be.
This is a pure controller, with no in-built sounds, so you need a good software piano. While I had a few software pianos (mainly the ones included with Native Instruments Komplete) I wanted to try one of the four that the VPC1 includes custom "touch curves" for - I ended up trying, then buying Pianoteq Stage, and the add-on Bluethner pack. I'd never tried a modeled piano before, and have been thoroughly impressed with it. Definitely recommended to try with this.
Be aware that it doesn't have a mod wheel, nor pitch bend. Fair enough; it's a piano controller. I have a few orchestral sample libraries that use mod wheel for dynamics, so when experimenting with them, I've just placed a small USB keyboard atop the VPC1, and used its mod wheel - and that works fine, though I've also experimented a little with using an iPad with the Lemur app, and I've had more fun with that, as I can create mod sweeps with inertia, etc. - if you're of a technical bent, try that. Having said that, I did get this intentionally as a piano controller, so most of the time I don't need - or want - a mod wheel.
The VPC1 is heavy; a good stand is a must. I'm using the K&M Omega stand, as it doesn't have annoying crossbars to whack your knees, and it's built very solidly, with a very discreet, minimal look that I think matches the VPC1 well.
