Keyboard:
Verygood soft keyboard with perfect after touch.
No hammer mechanics but not bad feeling to play on it. Keys are free from interfering plastic noises.
Sound:
Hot factory sounds, nice piano, realistic rhodes and verygood organ sounds.
But there is some digital noise in the sound, not too disturbing.
Sounds are undulate when the keys are pressed too much (I hope this will be improved when studiologic upgrade the firmvare. (1.0.0 now)).
Design, implementation quality:
Design is bit oldskool and newskool (i love it).
The quality of assembly is verry good but the button switchers are littlebit poor.
Faders and the screen is nice.
Overall, this is a great entry-level instrument.
