Rane DJ SEVENTY-TWO & SEVENTY-TWO MKII | How can I set the FX BPM to match my external audio source?

If you are using an external sound source, such as a turntable or CD player, you can manually set the BPM of the channel. This will mean that time-based FX are in sync with the audio. To set this, Hold Shift and press the Effects/Tap button multiple times at the desired tempo to manually set the BPM rate for beat-tempo effects, per channel.
