Load the practice pair to begin, or drop your own audio onto a deck.
Shortcuts pause while you type in a field. Space respects a focused button. Every action also has a visible control.
Speed changes pitch. Source BPM is entered manually for imported sounds; Match tempo changes speed but does not align beats. Cues play through the main output; there is no separate headphone channel. Load mono/stereo audio up to 40 MB and six minutes per deck (128 MiB decoded limit). Takes finish automatically at about ten minutes.
