JTC Pro is an advanced pedal with simplified controls. It's a dual switch stomp box with 6 hours of recording capability and 256 loop track memories.
It has independent controls for the looper and the drum: left footswitch (LOOP) controls recording, overdub, and start/stop of the looper. This switch also features NUX patented Smart TAP function, which automatically detects whether you want to control the looper or to set the tempo of the drum.
There are 2 different loop recording actions on JTC Pro; Record and Play (RP), and Record and Overdub (RD).
Right footswitch (RHYTHM) controls the drum and it adds drum fills during the performance. While the drum track is playing, hit the RHYTHM switch to add a drum fill and it will play until the end of the current bar. The longest drum fill is one measure (depending on 4/4 or 3/4 rhythms). If you hit the switch right on the 3rd beat, this drum fill will be 2 beats only.
