Simple: one pitch, a mod, sustain, velocity and heavy touch piano ... but no aftertouch. Connectivity super simple.

UTILIZATION

Keyboard super enjoyable for just 500 euros. Personally, I use it only at home, such as MIDI controller. It is perfect in this context-l.
Tranport on scne difficult, or else to a single instrument (Because no lcd screen!).

OVERALL OPINION

I use it for 6 months, connect a PC. Companion leisure seamless and flawless, and the corresponding fully my need. Report-quality unbeatable price.
