Plucked Tremolo

0:16

TREM mode with a sharp envelope creating rhythmic plucks.

Crystal Chaos

0:18

REPEAT mode with chaos and wear turned up, creating octave crystals.

Slow Duet

0:24

LOOPS mode with a long loop time and reach turned up so fragments return pitched up and down and reversed.

Sonic Adolescents

0:25

LOOPS mode with a healthy dose of fuzz, medium loop lengths and chaos turned up.

TREM: Give your sounds a classic tremolo sound, with volume shapes from a rounded sine through triangle and rising sawtooth to a hard square gate. Run it free or synced to your host tempo. STEREO PHASE offsets the two channels creating mild stereo motion all the way to a hard left/right alternation.
REPEAT: Repeat notes with up to 64 pitched copies. Five pitch shifting levels from two octaves down to two octaves up, independent decay and a separate feedback path for longer, evolving tails. CHAOS throws octave jumps into the pattern at higher settings.
LOOPS: Play up to six overlapping fragments of what you just played, spread across pitch, reverse playback, reading position and the stereo field. It's possible to freeze a phrase and play over it, or let LOOPS keep drawing from everything you've recently sent it.
WEAR and drive: WEAR layers tape wear, magnetic saturation, head coloration and digital crush after whichever mode is running. Drive your input through overdrive for a softer clipped voice, or FUZZ for harder clipping with its own sputtering decay.
