Frequently Asked Questions
It's a compromise; it offers some resistance and feedback, but lacks the full depth and responsiveness of a proper piano keybed. Expect a lighter, quicker feel.
It's a decent thickness; it won't withstand serious abuse, but feels much more substantial than plastic alternatives common at this price point.
While technically Class Compliant, consistent performance with iOS can be hit-or-miss depending on the device and driver support; a dedicated USB MIDI interface is recommended for stability.
