Five scratching phrases can be arranged freely based on the basis of half notes, quarter

, and icons
representing each phrase are projected on the top of the touch sensors. Users can
switch between the five scratching phrases by touching the projected objects. The five
phrases are always played in the tempo of the current rhythm track, and Bathcratch
outputs only the phrase selected by controlling the faders for each phrase.
Consequently, even if a user rubs vigorously and quickly, the output phrase is not
changed. Furthermore, when a user selects another phrase before the current phrase
has completed, a smooth transition is made using crossfading effects.
