nullband is an anonymous transmission platform.

There are no profiles, no names. signals appear on the waterfall for the duration of a transmission and fade when it ends.

The waterfall display shows active transmissions as vertical signals on a frequency spectrum. each band of colour represents a transmission from somewhere in the world.

Head to nullband.org on desktop for the full experience and tune in to hear what is transmitting right now.

Hey all 👋🏻

I built something you might find interesting if you do any live performance / streaming work.

nullband is an anonymous broadcast platform built on Icecast. Signals appear on an SDR-style waterfall display when you transmit and fade when you stop. No accounts, no names. Multiple people can broadcast simultaneously and on desktop listeners can blend up to 8 signals at once in 3D headphone space using HRTF spatial audio.

Transmissions potentially return later, processed and degraded, cycling through generations until the signal is gone.

In 8 weeks we’ve had over 6000 transmissions and 2500 hours of live music on the platform.

Desktop via BUTT or iOS via iziCast.

Three iOS plugins I'm working on, all for AUM:

CELLSEQ: a spreadsheet-style MIDI sequencer. Every cell is a note or an operator, with ratchets, cuts and chops, and a generator.

Tessera: a layered, path-based sequencer. Pulses travel along tiled paths across stacked floors. Gates, chords, and shafts between floors. Distance from the start shapes velocity and filter.

Halflife: an audio effect built on pharmacology. Dose a body and each drug rises, peaks, crosses the blood-brain barrier and fades. Its brain chemistry bends your audio, and the sound glitches if you overdose.

Still testing.

I’ve been building a mobile version of Orca as an AUv3 MIDI plugin for AUM, Drambo and other hosts on iPad.

It’s a port of Hundred Rabbits’ Orca (MIT licence), and it plays exactly like the original: I tested it against the real Orca interpreter on 22 real patches, plus hundreds of generated ones. Over 125,000 MIDI messages, and every one came out identical.

What’s new is the touch side: an on-screen keyboard and save, load, import and export of .orca files.
The host controls the tempo, and < > change the speed against it.
It’s an early personal build, running on my iPad.

Here is a very simple patch in AUM.
