Introduction
Thank you for purchasing the Raster 2. The Raster™ is a digital delay with a pitch and frequency shifter
integrated into the feedback loop. Forward or reverse delay can be shifted once or have continuously
shifted repeats. It delivers a wide range of sounds including modulated and harmonized delays, reverse
delays, chorus, arpeggios, infinite descents, chaotic self-oscillation, and continuously evolving sound-
scapes.
The core of the Raster™ is a clean delay with 1600 milliseconds of delay time. Three delay ranges allow
you to precisely dial in resonant feedback sounds and instantly change delay time with rhythmic shifts.
The feedback control has infinite repeats at 3 o’clock and chaotic, textured feedback loops at higher lev-
els. Knob responses are carefully tuned for exploration of self-oscillation and feedback on the verge of
blowing up. A tone control sweeps from dark analog-style repeats to digital clarity and emphasizes the
attack at higher settings. The left and right delay times can be set as a ratio, so a single knob changes
both in sync. The two delay channels can be arranged in series, parallel or ping pong.
Pitch shifting repeats up or down in semitone steps creates tempo-synced arpeggios and alien organ
sounds. The detune setting can dial in micro pitch shifts and chorused repeats. The left and right chan-
nels can be shifted by the same amount, a ratio, or opposite directions. At subtle settings, repeats evolve
in a way that sounds natural, but different from analog delays.
Beyond pitch shifting, a combination phase/frequency shifter creates subtle evolving repeats, dissonant
harmonies, and barber pole flanging. It can be pushed to extremes for ring modulation and inharmonic
shifted delays that distort and break apart.
The Raster’s modulation section has seven waveforms that can be assigned to delay time, pitch shift, or
amplitude (for tremolo). There are two random waveforms for glitchy pitch jumps, wow and flutter, and
broken tape deck effects. Envelope and inverse envelope enable dynamic flanging and pitch bent delays.
Stereo controls adjust the modulation amount and phase between channels, for subtle shifts or swirling
psychedelic washes.
We started designing version 1 of the Raster in 2012 and released it in 2015. It was a simple looking de-
lay pedal, but the controls were carefully tuned and all of the functionality fit together perfectly, making
it extremely fun to use.
While designing the Raster 2, we wanted to enable as many classic rack mount digital delay tricks as
possible while keeping the fast and intuitive control that made the original Raster so fun to use. All
of the parameters are always available, so you can mix and match different effects and explore new
sounds in between.
