Tape

Four lo-fi tape units for the Orthogonal Devices ER-301 Sound Computer: pitch that drifts, highs that sag, hits that pump, dust in everything. Run one at a time or stack all four into a full tape channel. Mono or stereo, anywhere in a chain.

The units

Unit What it does
Tape Wobble the transport Wow and flutter from a worn capstan. The wow lurches at the bottom of every cycle the way real tape drags; flutter is two sines at an irrational ratio so it never repeats.
Tape Tone the circuit A one-knob tone macro: flat at zero, then the top end folds down behind a resonant peak and the bass thins, ending in a honky resonant band.
Tape One the squash An SP-404-style compression sustainer. One knob from untouched to full pump (+36 dB of squeeze, +14 dB of makeup), with a transients knob for how much of each hit escapes the clamp.
Tape Dust the dirt A non-resonant low-pass held wide open while white noise drags it down, thousands of times a second.

Every dial except trans accepts CV through its sub-chain.

Design notes

Tape is not an emulation of any particular machine, and it doesn't aim to be wholly realistic - each unit chases the musical side of a tape artifact rather than the physics behind it. It was also voiced on melodic material rather than percussive, so mileage may vary with drums and other transient-heavy sources.

The artifacts ship as four separate units instead of one big tape channel so you can compose them: chain them in any order, leave parts out, or duplicate a stage - a second Tape Dust sanding at a different depth, a Tape One on either side of the wobble. On the ER-301 the chain is the patch, and small units keep that flexibility.

Install

  1. Download tape-x.y.z.pkg from the latest release.
  2. Copy it to ER-301/packages on the front SD card.
  3. Install from admin > Package Manager on the ER-301.
  4. The units appear under the Lo-Fi category in the unit browser.

Requires ER-301 firmware v0.6 or later. The package is pure Lua, so the same file runs on hardware and on the ER-301 emulator.

Building from source

The package is a zip of the Lua files - no cross-compilation needed:

make               # produces tape-x.y.z.pkg
make emu-install   # copy to the emulator's rear card (auto-installs on boot)

For development, the ER-301 SDK emulator gives a fast edit–install–listen loop.
