The NI404 lives on — as TOERN.
The NI404 was an open-source sample-sequencer loved by makers and musicians. But now, it's time for something new.
TOERN is its direct successor — reimagined, refined, and built for today's live performance and studio exploration. Standalone, expressive, and still open in spirit.

What’s new with TOERN?
Refined Hardware.
More robust, more portable, and ready for the stage — TOERN keeps the rotary+grid UI, but improves the casing, handling, and build process.
New Sound Engine.
Built from scratch with live play and sound shaping in mind. Samples, synthesis, modulation and more.
Focused Simplicity.
Fewer menus, faster navigation, deeper performance possibilities. Designed for flow, not fiddling.

Gratitude
Thank you to everyone who supported the NI404 — from contributors to testers to the curious builders. Your enthusiasm helped pave the way for TOERN.
Special thanks again to Paul Stoffregen and the Teensy team, and to Nic Newdigate for the fantastic teensy-polyphony library.
The legacy lives on — in a new form.
