Tapes on Tapes
8-Channel Magnetic Tape Delay Matrix & Generative Loop Laboratory
An esoteric multi-channel magnetic tape playground engineered by Ancient Apparatus. Inspired by the hypnotic reels of 1970s tape loop pioneers, Tapes on Tapes weaves eight independent stereo tape loopers into a living feedback matrix. Route any channel into any other, reverse time at loop boundaries, modulate capstan motor drift, and dissolve your sound in lush analog saturation and resonant decay.
The Tape Weave Concept
Traditional tape delays are linear repeats: your signal enters, hits a playback head, and decays. Tapes on Tapes re-envisions tape as an interconnected, multi-dimensional web. Eight independent tape loops spin simultaneously at distinct speeds, phases, and splice lengths. Channels can ingest live incoming audio—or feed directly into each other. A forward loop in Channel 1 can resample into a reversed, pitch-down loop in Channel 4, which cascades into a ping-ponging tape loop in Channel 7, creating infinite self-evolving ambient tapestries and polyrhythmic textures.
8 Independent Tape Heads
Each channel has its own dedicated 10-second stereo circular tape buffer, variable splice length window, periodic capture gate engine, and smooth tape motor varispeed.
Cascading Matrix Feedback
Select any channel (CH 1–8) as the input source for another channel. Build complex feedback networks, recursive tape bounces, and evolving generative soundscapes.
Analog Tone & Degradation
Hyperbolic tangent tape saturation, warble/wow motor modulation (2.2Hz flutter), bit depth decimation, and resonant low-pass filtering with dynamic Q sweep.

Selects the audio feed for the channel's write head. Set to IN for live external instrument/microphone audio, or select CH 1 through CH 8 to ingest the output of any other tape loop.
Options: IN, CH 1 – CH 8Dictates the tape travel direction. FWD (normal forward), REV (reverse tape spin), ALT (ping-pongs back and forth on loop boundary), or RNDM (probabilistic direction coin-toss).
Modes: FWD / REV / ALT / RNDMSets the physical length of the active tape loop splice window. Ranges from ultra-short micro-splices (sub-second granular repeats) up to 10 seconds of expansive room-scale tape loop.
Range: 0.1s to 10.0sControls the periodic capture gate engine. Opens the tape write head to record a slice of audio, then closes the gate to let the loop spin, degrade, and repeat without overwriting incoming material.
Interval: 0.1s to 10.0sDetermines how much existing tape magnetic flux is preserved on each loop pass. At 1.0 (100%), loops sustain indefinitely; as you turn it down, older layers gracefully dissolve into ambient tape noise.
Range: 0.00 (Single Tap) to 1.00 (Infinite)Displaces the read playhead relative to the loop boundary. Allows polyrhythmic phasing and Steve Reich-style phase-shifting counterpoints between multiple channels with identical splice lengths.
Range: 0.00 to 1.00 (0% – 50% splice shift)Controls the capstan motor drive velocity with seamless 20ms anti-zipper interpolation. Slowing the tape drops pitch and doubles loop time; speeding it up pitches audio upwards into shimmering tape flutter.
Range: 0.25x (Double Octave Down) to 2.00xIntroduces mechanical reel eccentricity, capstan belt slip, and wow/flutter motor instability via a dedicated 2.2Hz sine-drift modulation engine that bends tape pitch with vintage tape cassette character.
Range: 0% (Pristine) to 100% (Melted Cassette)State-Variable TPT low-pass filter featuring a dynamic auto-resonance algorithm. As cutoff sweeps below 19kHz, the Q resonance dynamically swells to create analog tape-head resonant warmth without harshness.
Frequency: 20 Hz to 20,000 HzApplies hyperbolic tangent (τανη) soft-clipping tape drive. Compresses peaks, fattens bass, and introduces musical odd harmonics that glue complex multi-channel loops together.
Range: 0.00 (Clean) to 1.00 (Heavy Tape Drive)Decimates sample bit depth down from studio-grade 24-bit floating point into crusty 8-bit, 4-bit, and vintage sampler territory, delivering early digital delay grit and crunchy loop artifacts.
Range: 2.0 bits to 24.0 bitsControls the individual auxiliary post-fader send level from this tape channel into the global Master Reverb engine, giving you precise depth placement for each loop.

Tutorial Recipes
Use these recipe templates as launchpads for your own generative tape experiments in Logic Pro, AUM, Ableton Live, or Standalone mode:
The Disintegration Loop
Hypnotic, decaying ambient tape study inspired by William Basinski.
- Send a slow piano phrase or acoustic guitar chord into CH 1.
- The 8-second capture rate stamps a slice into memory, then closes the gate.
- Over 3 to 5 minutes, each pass sheds top-end frequencies into the warm saturation while the ALT ping-pong motion breathes in reverse.
Polyrhythmic Matrix Weave
Cascading generative drone where three tapes re-sample each other.
- Feed a single staccato pluck or melodic note into Channel 1.
- Channel 2 captures Channel 1 in reverse an octave down (0.5x speed).
- Channel 3 grabs the reversed octave from Channel 2 and pitches it up (1.5x speed). The three loops slide past each other infinitely without repeating the same alignment twice.
8-Bit Glitch Cassette
Granular micro-loop stutter, crushed digital artifacts, and random jitter.
- Route a steady drum pattern or percussive loop into the input.
- The sub-quarter-second splice creates an instant micro-stutter delay.
- With DIR set to RNDM, the tape head randomly reverses at splice borders, generating chaotic circuit-bent glitch bursts.
The 8-Tape Shimmer Chorus
Massive wide stereo chorus built by staggering all 8 channels.
- Click COPY on Channel 1 and paste across Channels 2 through 8.
- Slightly alter the Offset and Speed on each channel (0.992x, 1.004x, etc.).
- Pan odd channels to the left and even channels to the right to create an astonishingly lush 8-voice tape flanger/chorus swarm.
