I ve been using this since 2013....and I'm pretty well satisfied.Honestly its not for pros,but if its gonna be your home studio,defenitely you must go for it....Simple plugin and play ,USB powered controller.... also comes up with a pressure-sensitive, semi-programmable interface for performing music through a tablet or computer.
It's...not great. I bought it in a Black Friday sale and there are some positives, so let's get those out of the way:
Ok, so that's the good. The bad is that the quality is pretty terrible. Things stopped working properly almost immediately and after a few months the volume knob didn't do anything and the volume would stay stuck on around 55 (I say around because it was never still on it...constantly fluctuating very rapidly up to 10 in either direction) and the octave buttons were finicky, often either not responding or going up 2 octaves. I didn't abuse mine, it just started falling apart. Now it sits in my closet unused, which is probably how it will stay. Maybe if I build my own synth one day (lol) I can cannibalize the actually pretty good keybed.
