## What is Wodnesdaeg?

Wōdnesdæg is sixty-four sine waves tuned to one chord and left to ring. Nothing is triggered, nothing decays. The instrument is the chord itself, and what you hear is the beating between waves.

Two banks of sixty-four sliders run across the screen. The upper bank is how loud each wave is. The lower bank is how far each wave sits off its own note. Sitting exactly on the note, sixty-four waves have nothing to beat against and the chord is flat. Move one and a slow pulse appears. Move twenty and the chord starts to breathe.

TEMPER sets the tuning system, so the same chord can be equal-tempered, just, or anything between — and the difference is audible immediately, because sustained sine waves show a tuning system more plainly than any other sound.

Choose key, scale and how the chord is stacked. Set the spread of each band. PLAY steps the music through a sequence; the microphone can step it too, listening for a clap or a voice in the room. Load a sound file into the deck and layer another over it, mixed by addition, wave-folding, ring modulation or bitwise XOR.

At the output: tape wear with independent wow and flutter per channel, reverb, compressor, limiter and EQ.

Landscape only. Everything happens on the device: no accounts, no network, no analytics. The microphone measures loudness only and records nothing. Headphones or a decent speaker recommended — much of this instrument is in the low end.

## Version history (last 4 releases)

### 1.1.3 — 2026-09-30

・VOICE now offers PURE / ANALOG. ANALOG bends the waveform itself for a
　less machine-like drift.
・The sixty-four voices no longer start together; their onsets are staggered.
・The output no longer passes through master tone colouring — only the soft
　ceiling remains.
・The lower row is relabelled LIFT, the panel name moved to the top, and the
　knobs calmed down.
・The ground cycles through a day's light (one full day every twenty minutes).

### 1.1.2 — 2026-09-28

The keys around the screen now carry their names, so it is clear what each one opens. The two long sliders are labelled as well, and the panels have a little more detail — a fine rule around each bank, quarter marks along the edges, and a centre line on the tuning row.

### 1.1.1 — 2026-09-25

Small fixes and refinements.

### 1.0 — 2026-09-24

No release notes.
