Engage QuietTime’s piano silencer with the flip of a switch, stopping the piano hammers right before they hit the strings. While your piano is silenced, the Optical Record Strip underneath the keys captures the MIDI data you create and sends it straight to your headphones. Since QuietTime’s cutting-edge optical sensor technology is hidden beneath the keys and completely contact-free, it doesn’t affect your piano’s touch, giving you the freedom to play silently with absolutely no compromises.
