The TAP button on the Spark 2 is designed to set the tempo of delay effects and the looper in the signal chain.
Once you power on the Spark 2, the LED on the "TAP" button will start flashing in red, indicating the tempo set by the delay and modulation effects.
To adjust the tempo, simply tap the "TAP" button a few times at your desired speed. The blinking will change to match the tempo you’ve set.
