Tap Tempo
If you want to match Circuit’s tempo to another piece of music and you don’t know its BPM, you 
can use Tap Tempo. Hold down Shift 
19
 and tap the Tempo button 
14
 in time with the track 
you’re listening to. You need at least three taps for Circuit to change its tempo setting to your 
manual input, and will then calculate the BPM by averaging the last ve taps.
You can use Tap Tempo at any time, but if you’re in Tempo View, you’ll see the BPM display 
update itself to the tap tempo.
Swing
By default, all steps in a pattern are equally spaced in time. At tempo of 120 BPM, a 16-step 
pattern will repeat every 2 seconds, making the steps one-eighth of a second apart. Altering the 
Swing parameter from its default value of 50% (the range is 20% to 80%) alters the timing odd-
numbered steps (the off-beats); a lower swing value shortens the time between an odd beat 
and the previous even beat, a higher Swing value has the opposite effect.

Swing can be used to add an extra “groove” to your pattern. Note that as it is the odd steps that 
are “swung”, these can be interpreted as 1/16-notes (semiquavers).
