NOIZETOYZ

A hardware synth wired straight into the AT Protocol. Play a key, scrub a sample, fold a wave, sweep a filter — a real board across the room hears it and plays it back, live, the same second.

Two patches, one substrate

Patch 1

Keys → Board

A browser interaction — a key, a scrub, a wavefold, an FM sweep — becomes a real, signed music.atproto.noizetoyz.synth.note record. A relay watches the network for it and re-broadcasts it live; a Wemos D1 mini running Mozzi turns it into one of six real synthesis techniques and draws the note name and a decaying waveform on its OLED — same room, same second.

Patch 2

Sensor → Feed

A BMP180 temperature/pressure sensor — with a DHT22 humidity sibling — on the same boards writes into Live Data Streaming's existing sensor-reading collection over WiFi. No separate backend, same substrate, read back out through the live readout above.

Signal path

Every jack below is a real network hop a note actually makes, keyboard to speaker.

Live out

Pulled straight from HappyView's read API, same feed the board itself is playing from.

Patch list

Six real Mozzi techniques, not custom DSP — flip one on from the player.

Tone

A plain note, optionally with tremolo, delay, or reverb.

Scrub

Scrubbing through a real sampled wavetable.

Fold

Wavefolding distortion laid over a tone.

Filter

A resonant lowpass sweep on a sawtooth.

FM

Two-operator frequency modulation.

Pluck

A plucked, decaying envelope.
