The core of the Raster is a clean delay with up to 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 levels. 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 channels 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.
The Raster’s modulation section has seven waveforms that can be assigned to delay time, pitch shift, or effect level (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.
