ARP input can be used to produce multi notes during one sequencer step. (ratchating) ARP function is controllable with ARP ENABLE input. An installed LCD shows tone, that is set up with TUNE knob, RANGE counter and OCTAVE counter. With EXACT toggle button tone will be tuned to exact halftone level.
