Keel is a rock-solid virtual stand-in for your audio interface — so when a cable gets kicked or macOS reshuffles your devices mid-show, nothing drops. No re-mapping, no scramble before you go live.
A rock-solid virtual stand-in for your audio interface — so a kicked cable or a macOS device shuffle never drops your show.
You're 30 seconds from going live. Someone bumps the USB cable behind the rack. The interface drops — and your DAW dumps its input mapping. Forty channels, suddenly unassigned. Now you're rebuilding the routing with the countdown running and the room filling up.
If you've run live sound off a Mac, you know the feeling. The hardware is never the weak link people expect — it's the moment Core Audio re-enumerates the device and the DAW loses the thread.
Point your DAW at the Keel device instead of the interface. Keel mirrors your real interface, bit-for-bit, on its own steady clock. When the hardware drops, Keel stays put; when it comes back, audio resumes — and your DAW's inputs never moved.
It isn't a mixer, a virtual cable, or an app-to-app router. It keeps a single hardware interface rock-solid for your DAW, so a disconnect never becomes a dropped show. If you need to move audio between apps, that's a different kind of tool — Keel is a reliability layer for live capture and playback.
The device your DAW records and plays through is always present, whatever the hardware does.
Keel mirrors your audio sample-for-sample on the interface's own clock. What goes in is what comes out.
USB drop, power blip, Core Audio re-enumeration — Keel rides it and hands back cleanly.
Mirror inputs and outputs; multi-interface rigs get a named, stable device each.
No Audio MIDI Setup gymnastics, no reconfiguring before each service.
Runs fully offline after activation. Whether you're capturing inputs or running backing tracks, the device never drops mid-set.
Install once. Keel publishes a stable, named device for each interface and holds it there — no Audio MIDI Setup gymnastics before each service.
Anyone running a DAW into a hardware interface on a Mac, where a dropped device means lost inputs and outputs — on stage or in the studio.
Multitrack capture and livestream off a Mac, week after week.
Ableton, MultiTracks Playback — click and stems out to FOH. The tracks never drop mid-song.
When the DAW is in the signal path on stage or in the truck.
A DAW-based audio chain that can't drop while you're on air.
Long takes where a mid-session interface hiccup can't cost the take.
Keel runs the church's livestream on a real 48-channel front end into PreSonus Studio One — every service, week after week. Zero dropped inputs or outputs, and effectively zero clock drift (−1 ppm) measured across an 11-hour run.

No. Keel is a transparent mirror — bit-for-bit, on your interface's own clock, with no processing and no added latency. A recording through Keel is identical to a recording through the interface directly.
The Keel device stays present, so your DAW keeps running and never loses the device — your input and output mapping stays put. When the hardware reconnects, audio resumes automatically — no re-mapping, no reset.
Apple Silicon and Intel, macOS 13 (Ventura) and later. It's a notarized audio driver installed with a standard signed installer — no Xcode, no tinkering. See the system requirements for the exact per-version feature notes before relying on it for a live show.
Keel appears as a normal Core Audio device, so it's DAW-agnostic. It's used in production with PreSonus Studio One; Logic, Reaper and others see it the same way.
It isn't — the trial is the full product for 14 days, no watermark or channel limits, so you can test it under real conditions. After 14 days it asks for a license.
No. Activation is a one-time step; after that Keel runs fully offline.
No — those route and mix audio between apps. Keel does a different job: it keeps one physical interface rock-stable for live capture and playback, so your DAW never loses it. Different problem, different tool.
