If independent left/right shift is enabled, the LEDs will show the control position instead of the patterns
above.
Detune
Detune mode smoothly shifts from a 4th down to a major third up, with emphasis on small pitch ratios.
Small shifts created chorused or detuned sounds. When used with delay, subtle detuning will cause
each repeat to change slightly, creating a unique but interesting and natural evolution as the sound de-
cays.
The Shift left/right balance control will keep the left (CCW) or right (CW) delay shift constant while
reducing and then inverting the detuning of the other delay. Turning the control counter-clockwise will
keep the left shift constant while reducing, disabling, and then inverting the right delay shift. Turning the
control clockwise will keep the right shift constant while reducing, disabling, and then inverting the left
delay shift. At the minimum and maximum settings, the delays will be detuned in opposite directions.
The SHIFT control will aect both channels proportionally.
Around 12:00, the SHIFT control will add phase shifting. Phase shifting with very short delays is good
for bubbling resonant sounds. With longer delays, the repeats evolve in a way that sounds dierent from
analog or tape delays.
Higher and lower SHIFT settings use frequency shifting (single sideband modulation), which destroys
the harmonic relationship between signal components. Each partial is shifted up or down by a fixed
number of Hertz (0-500). Frequency shifting creates metallic sounds. With frequency shifting in the
feedback loop, the harmonic structure of the notes is pulled farther apart with each repeat.
The dierence between pitch shifting and frequency shifting can be illustrated by looking at the first 5
harmonics of a A above middle C (A440) when the fundamental is shifted to 660 Hz using pitch shifting
and frequency shifting.
