Lo-Fi Emulation

  • Tape modulation effects (Wow, Flutter, Crinkle, Dropouts) carefully modeled after spectral and waveform data collected from all kinds of different tape players.
  • 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 1970’s synthesizer.
  • Compression inspired by a vinyl simulator found in a famous sampler from the early 2000’s.
    • Option to swap Compression parameter for 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 (before or after the other effects).
  • Capable of infinite sustain.

Touch Modes

  • 6 playful modes that can be activated momentarily or latched, and interact with all of the tape 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 – Captures a small slice of audio and divides into tiny subdivisions for glitchy effects. Synchronizable via MIDI clock. Includes a resampling option that can sample new audio by detecting transients.
    • Crushed Cassette – Provides continuously variable sample rate reduction as well as bit depth reduction down to 4 bits with µ-law companding.
    • Disintegration Loop – A looper with controls for loop decay, speed, and direction. Each time your loop repeats, it gets re-run through all of the tape effects.

Four-Track Looper

  • Allows up to 4 separate stereo loops.
    • Length per loop: 40 seconds at 0.5x speed, 20 seconds at 1x speed, 10 seconds at 2x speed.
  • Each loop has separate controls for: playback direction (forward or backwards), playback speed (continuously variable from 0.5x to 2x), track volume, and track speed scale (quantization).
  • Overdub infinitely on any track.
  • Overdubbing possible at any speed.
  • Looped sounds can be processed by the tape effects.
  • Synchronizable via MIDI clock.

Presets, MIDI Control, CV

  • Use 8 onboard preset slots to save your settings, or queue them up using a preset device.
  • All parameters are fully controllable via MIDI, CV, or an expression pedal.
  • Directly compatible with all of your favorite MIDI controllers – no external MIDI box required.
    • Internal jumpers available to switch between TRS MIDI A (standard), B, or CBA.
  • CV control up to 500Hz.
  • Download our Max for Live devices to control Ribbons with MIDI using Ableton.

Four-Voice Sine Wave Synthesizer

  • Connect to a MIDI keyboard and start playing.
  • +/- 5 semitone pitch bending.
  • Includes controls for attack and release.
  • Synth voices can be modified by the tape effects and used with the four-track looper.
