I was looking for a small midi keyboard to plug into a laptop, with enough buttons to play (with two hands) and able to walk everywhere, landing on his knees watching TV and easy storage (small apartment).
37 keys, USB, 40cm long, 10 wide, trslger, very small, it stands on a corner table. It's simple and works.

UTILIZATION

Well, it's basic, no knobs or controls, the buttons are small and just "on / off".
The touch is enjoyable synth for this type of product but this is not a well Sr. CRITERIA choice.
I do not load the driver Russi XP but the keyboard is recognized immediately and works well as a. trs
The manual is nothing, except for some programs comes with: a squenseur (which supports VSTi) software aprentissage keyboard, DMOS (B4 etc.), recreational Programs but of little use ...

OVERALL OPINION

I for 1 month. No problem except tmoin diode that lights up when she wants.
I use it mainly as an amateur for running VSTi Synthedit live in and tweak a little.
The +: mini footprint that makes me the fate that I ds 5 minutes (more often than a large keyboard) and it fits in a drawer.
The - is the lack of controls, but it would dtriment at the waist.
To touch, ok it's not the top (nothing to do with my Clavinova, of course, but more convenient), but this is not the motivation for this kind of purchase.
At 50 euros, there's no cheaper and no smaller either (with 3 octaves). IDAL is for a laptop (at trs del is more portable). It's a gimmick but allows for more music and more often. Mission Russia.
To note, I would be tempted to over 10 as there is no real competition in this type of product but you can probably do better (if it is also small).
