## What is Thunresdaeg?

Þunresdæg has no samples and no recordings in it. Every sound comes from three oscillators built out of small equations run over and over — the tent map and its relatives — fed into a board of effects you patch with cables.

Nothing is random. The maps are deterministic: put the instrument back where it was and the same sound comes back. What sounds like noise is a number sequence that has not repeated yet.

The board holds six pedals — two phasers, a bucket-brigade delay, a ladder filter with an envelope follower, a ring modulator, a modulated delay from chorus to flanger, an FM oscillator with hard sync, and a stepped bank of eight band-passes. Patch them in any order, feed any output back into any input, and cross the paths through a 4×4 matrix.

The eight XY pads are not knobs. They are control voltage sources. What each one moves is decided on the board, so the same gesture can sweep a filter, drive a phaser and retune an oscillator at once.

The camera can take over the pads: light and movement in frame become the pointers. Your own sound can be played through the board from the microphone. Presets store the whole instrument — cables, matrix, every knob and switch, the pads, the oscillators, the exit EQ and the camera settings.

Landscape only. Everything happens on the device: no accounts, no network, no analytics. Camera frames are read and discarded, never stored. Headphones or a decent speaker recommended.

## Version history (last 3 releases)

### 1.1.2 — 2026-09-29

The camera now tracks what it sees far more accurately, and reads the frame as sixteen cells per pad. Each slider on a pedal panel shows a thin meter underneath, so you can see which patch cable is feeding it and how hard. The four corner keys carry their names, the sliders line up, and the pads are drawn as a plain frame.

### 1.1.1 — 2026-09-25

Small fixes and refinements.

### 1.0 — 2026-09-24

No release notes.
