Getting Started
The Raster 2 is a stereo digital delay with two pitch and phase/frequency shifters integrated into the
delay structure. The delay lines and shifters are independent, but are usually adjusted in ratios or by
"tilting" the effect to the left or right channel. The delay structure is configurable, so that the shifters
can be inside the feedback loop for continuously shifting repeats, or outside the feedback loop to shift all
repeats to the same pitch. The two delay lines can be in series for stacked delays (mono), parallel stereo
delay lines, or cross feedback (ping pong) with the repeats swapping between left and right channels.
Almost all parameters have stereo controls, Used subtlely, you can create delays that shear apart or
gradually pull towards one channel, micro pitch shifting, and random stereo chorusing. It is also possi-
ble to create chords, octave up+down shifts, arpeggios, quadrature or inverted delay modulation, and a
wide variety of other delay- and pitch-based effects. Stereo functions are labeled in gray and accessed
by holding down the
ALT button. They are saved to presets, and remembered when the pedal is turned
off. Secondary (alternate) functions allow us to pack in more functionality without increasing the size or
cost of the pedal, but they can make it easier to get lost while you are editing. To make it less confusing,
all of the alternate controls are off when the corresponding knob is at center (12:00).
The modulation section has seven LFO waveforms, envelope, and inverse envelope modulation. Delay
modulation changes the pitch - like an analog or tape delay - as the Raster reads and writes the delay
memory faster or slower. Modulation can also be assigned to the wet signal amplitude for tremolo ef-
fects, or the shift amount for pitch and frequency modulation.
This section will help you get started with the Raster 2. The following sections will discuss the controls
in depth and discuss how to create a wide range of delay- and pitch-based effects.

Plugging In
The Raster 2 requires an isolated power supply that can supply at least 250 mA of current (300+ mA
preferred). Most problems are due to inadequate or overloaded power supplies. See our knowledge
base for information about specific power supplies.
If you purchased your Raster 2 used, first do a factory reset to initialize all settings to their defaults
(page 27).
The Raster 2 has TRS stereo inputs and outputs, configurable using the web editor. The default config-
uration is mono in/stereo out, but you can plug in a mono cable if stereo output is not needed. A variety
of input/output configurations, bypass modes, and maximum signal levels are available to adjust the
Raster for your pedalboard or studio.
Connect your instrument to the Raster's input using a TS (mono cable), and connect the Raster's output
to your amplifier or audio interface using a TS cable.
Turn down the volume on your amplifier and connect a power cable to the Raster, then adjust your am-
plifier's volume to a comfortable level. Press the right footswitch to turn on the Raster.
