Tap Tempo
This button affects the speed of the effect whenever the tremolo
and/or autopan is set to TEMPO SYNC mode.  In that mode, you
can tap this button along with the music to set a new tempo.  The
Tap Tempo light will  flash at the current tempo.
Tap Tempo technique
For a reliable tempo setting, make  from  four to eight taps in a row
at a consistent speed, especially if you’re changing the tempo
drastically.  Watch the  flashing of the light to see what tempo the
Ampliton is currently at.
Adjusting tempo with audio input
After the basic tempo has been set using the [TAP TEMPO]
button, it is possible to make small adjustments to the tempo via
the audio input. You do this by “tapping” on the instrument
(playing sharp chords, or beats, without sustain or notes
inbetween) at almost the same speed as the Ampliton’s tempo
LED, or by slightly changing the speed of a drum machine  feeding
the inputs.  The Ampliton can derive a beat  from a complex
musical input, as long as it is reasonably close to the original
“tapped” tempo.  The tempo can adjust up or down about 15%
from the original tempo tapped in.
How Tap Tempo works with Tempo Sync and
the Rate knobs
When TEMPO SYNC mode is enabled, the rate of the modulation
will be based on the tempo currently being  flashed, multiplied by
the position of its [RATE] knob:  when it’s in the middle position
(around “12 o’clock”), the speed of the triangle, square, pattern
etc. wave will be the same as the tempo.  See the earlier
descriptions of the [RATE] knob and Tempo Sync  for more
information.
