Lo-Fi Emulation

  • Tape modulation effects (Wow, Flutter, Crinkle, Dropouts) carefully modeled after spectral and waveform data collected from all kinds of tape players, ranging from perfectly functioning to completely broken.
  • Dedicated dry/wet mix knob to dial in complex vibrato and chorus sounds.
  • 24dB/octave four-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.
  • Static hiss and clicks & pops.


  • A beautiful stereo reverb designed from scratch, with controls for dry/wet mix, decay time, and where the reverb goes in your signal chain.
  • Capable of infinite sustain.

Touch Modes

6 immersive modes that you can activate momentarily or latch, and interact with all of the different effects:

  • Magnetic Dance — Creates a drone of sound using a micro-loop. Tune it to chords; play it forward or backwards.
  • Tape Stop — Slows down and bends the pitch of your audio in real-time, then picks it back up, with separate controls for stop and start times up to 10 seconds.
  • Broken Machine — Makes a garbled mess of your incoming audio. Use it subtly for some added tape modulation or at extreme settings for rewind effects.
  • Repeater — Endlessly repeats a tiny slice of audio that you can subdivide for glitchy beat repeat effects. Synchronizable via MIDI clock. Includes a re-sampling option that detects transients, like a snare hit or a pick attack.
  • Crushed Cassette — Provides continuously-variable sample rate reduction as well as bit depth reduction down to 4 bits with µ-law companding. Dial in haunting distortion and artifacts to taste.
  • Disintegration Loop — A sound-on-sound style looper with controls for decay, speed, and direction. Each time your loop repeats the effects are re-applied, degrading into abstraction over time.

Four-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 discrete 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 via MIDI clock.

Four-Voice Sine Wave Synthesizer

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

Presets, MIDI Control, CV

  • Explore 8 factory presets that showcase patches, or use the slots to save your own settings.
  • All parameters are fully controllable via MIDI, CV, or an expression pedal.
  • 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.
