Notes on Tap Tempo

The Tap Tempo feature of the SFX-07 is an incredibly powerful tool that

takes this pedal way beyond what "normal" tremolos can do. It totally

removes the guesswork of trying to sync your trem pulse to a song's

groove. Simply tap your foot on the Tap Tempo footswitch and you'll

hear the tremolo effect fall right in line, right on the downbeat, every

time—with whatever Wave, Depth, and Shape settings you've chosen.

If the Rate/Multiplier Mode switch is set to Rate, hitting the Tap Tempo

footswitch will generate two trem cycles per tap. When this switch is set

to Ratio, you can choose between one, two, three, or four trem cycles

per tap, depending on which quadrant the Rate/Ratio knob is set to.

Hint: The triplet setting (three cycles per tap) works great over shuffle

grooves.

Another cool thing about Ratio mode is that you can change rhythmic

subdivisions on the fly and they stay on the downbeat. Previously, this

would be tough to pull off in a live situation for guitarists. It might seem

like a studio trick or a DJ effect, but with the Tap Tempo footswitch, it is

now within your reach. In Ratio Mode, set the Rate knob to the 1x (fully

counter-clockwise) quadrant and enter the tempo of the song you're

playing with the Tap Tempo footswitch. Hit a chord and, while it's ringing,

rotate the Rate/Multiplier knob through the 2x, 3x, and 4x quadrants.

What you'll hear is your chord pulsing quarter-notes, then eighth-notes,

then triplets, and finally sixteenth-notes, all in sync, and all hitting on

the downbeat. The Shape Shifter has a "top speed" of 20hz. If you've

already reached this top speed in the tap section, then increasing the

Ratio can no longer have an effect.
