Got a delay effect on your pedal/synth/effects rack? Accurate delay times are there on the screen for you to use.

Got a LFO parameter on your effect or synth patch? The LFO rates are also on screen to set the effect in time with the track.

If you already know the BPM use you keyboard or the keypad to enter the BPM directly to get the LFO and delay times.

- Tap in time with any music to find the tempo, correct delay times and LFO frequencies.
