While "Hot Cues" mode is enabled, hold down the "CUE MODE" button and touch a section of the strip to delete it's associated hot cue.
Center is 100% pitch (or otherwise no pitch adjustement).
Move the slider to the left side to slow down the track, or to the right side to speed it up.
Hold the assigned deck button for more than 3 seconds to un-assign the unit from a VirtualDJ deck so that another unit can control this deck.
A bigger pitch range will give you a bigger range of possible BPM matches, but the pitch slider movement will be less accurate.
While the deck is playing switch the motor off to get a classic vinyl brake effect.
