Modulation Controls
Adjusts the modulation LFO frequency from approximately 0.05 - 10 Hz. The modulation waveform LED
blinks at the LFO frequency (if MOD DEPTH is not o).
When envelope or inverse envelope modulation is selected, this control will have no eect.
The MOD PHASE L/R (ø) control adjusts the relative phase of the modulation between the left and right
delay lines. At 7:00 and 5:00 the LFO waveforms will be inverted relative to each other. At approximate-
ly 9:30 and 2:30, the LFO waveforms are 90° out of phase (quadrature), which creates a wash or tum-
bling eect. At any setting besides 12:00, the random LFO waveforms are independent.
The setting is stored in presets and remembered when the pedal is turned o.

The Raster's modulation section has seven LFO waveforms and an envelope follower that can be as-
signed to delay time (default), shift amount, or wet signal amplitude (tremolo).
The LFO waveforms are bipolar (-1 to +1). The RATE control adjusts the LFO frequency from approxi-
mately 0.05 Hz to 10 Hz. It can be synced to tap tempo and MIDI clock using the editor or MIDI continu-
ous controller messages. The modulation waveform LED blinks at the LFO frequency (if MOD DEPTH is
not o).
The modulation depth L/R control ([ALT]-DEPTH) will decreate the modulation amount on the right chan-
nel as it is turned left, and vice versa. It emphasizes modulation on the left (counter-clockwise) or right
(clockwise) channel, with the maximum set by the DEPTH control. Moving the DEPTH control will aect
both channels proportionally.
The RATE control has no eect on envelope and inverse envelope. Envelope modulation is unipolar,
wither up (envelope) or down (inverse envelope. For stereo inputs, the envelope detector uses the maxi-
mum of the left and right channels.
Delay modulation
(Default)
Delay modulation changes the pitch - like an analog or tape delay - as the Raster reads and writes the
delay memory faster or slower.
