The Hydrasynth Desktop is a fantastic studio instrument! I mentioned value, because I have noticed the price of this item fluctuate recently, and know that I got a great deal.
The great deal is reflected in the build quality, features, modulation options and immediacy. I have never played a keyboard before, which is a big reason I chose the desktop. Space was also a big selling point, as was being able to create sounds easily using the onboard pads, which are very playable.
Why is the Hydrasynth Desktop not perfect? I deducted a star from the Handling section, because of the recessed back panel. This is definitely a pain, albeit minor I suppose, and was not or definitely not a deal breaker.
Finally, the Hydrasynth Desktop is very easy to play and modulate extensively straight out of the box, and this statement is coming from a novice who will be happily learning quite quickly using this instrument.
