Lo-Fi Emulation

  • Physically-modeled tape modulation effects: Wow, Flutter, Crinkle, Dropouts
  • 24dB/octave 4-pole virtual-analog low-pass and high-pass filters, modeled after the filter of a classic 1970s synthesizer
  • Compression inspired by a vinyl simulator found in a famous sampler from the early 2000s
    • Option to swap Compression parameter for Tape Saturation
  • Dedicated dry/wet mix knob to dial in complex vibrato and chorus sounds
  • Static hiss and vinyl crackle

Reverb

  • A beautiful stereo reverb designed from scratch
  • Can be placed pre- or post- tape effects
  • Capable of infinite sustain

Touch Modes

Playful, on-the-fly performance effects that transform your incoming audio in unique ways. Touch Modes can be activated momentarily or latched, and some provide additional lo-fi character:

  • Magnetic Dance — A chordal looper that captures a segment of audio and turns it into a stunning drone
  • Tape Stop — Slows down and bends the pitch of your audio, then picks it back up, with flexible timing controls
  • Broken Machine — Use it subtly for added tape modulation. Push it to extremes for rewind effects and explosive clouds of noise
  • Repeater — Endlessly repeats a slice of audio that you can subdivide for CD skipping sounds. Inspired by classic roll/slip roll effects. Includes a resampling option that detects transients. Synchronizable to MIDI clock
  • Crushed Cassette — Continuously-variable sample rate reduction and bit crushing down to 4 bits with µ-law companding. Dial in haunting distortion and artifacts to taste
  • Disintegration Loop — A sound-on-sound looper with controls for decay, speed, and direction. Each time the loop repeats, your effects are re-applied, degrading into abstraction over time
  • UnrealPlayer — A spectral processor that emulates artifacts and imperfections of early audio streaming and file-sharing eras. Grainy, bubbly, and strangely reverberous, this mode feels unmistakably modern

4-Track Looper

  • Record up to 4 separate stereo loops that run through your effects
  • Length per loop: 40 seconds at 0.5x speed, 20 seconds at 1x speed, 10 seconds at 2x speed
  • Each track has independent controls for: volume, direction, speed (continuously-variable from 0.5x to 2x), and speed scale (quantization)
  • Overdub infinitely on any track
  • Overdub at any speed
  • Loops can be synchronized to MIDI clock
  • Touch Modes can be used while your 4-track loops are playing back

4-Voice Sine Wave Synthesizer

  • Play Ribbons as your instrument using a MIDI keyboard
  • +/- 5 semitone pitch bending
  • Adjustable attack and release controls
  • Synth voices can be modified by the effects and used with the Touch Modes or 4-track looper

Presets, MIDI Control, CV

  • 8 factory presets
  • Save up to 32 presets using MIDI
  • All parameters are fully controllable via MIDI, CV, or expression
  • Directly compatible with your favorite MIDI controllers — no external MIDI box required
  • Internal jumpers available to switch between TRS MIDI Type A (default), B, or CBA
  • CV control up to 500Hz
  • Free Max for Live devices to control Ribbons with MIDI in Ableton
