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 off).
When envelope or inverse envelope modulation is selected, this control will have no effect.
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 effect. 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 off.

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 off).
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 affect
both channels proportionally.
The
RATE control has no effect 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.
Shift modulation
