macOS reliability layer for live audio

Your interface can fail.
Your show won't.

Keel is a rock-solid virtual stand-in for your audio interface. Whether you're recording inputs or running backing tracks, it keeps one stable device between your hardware and your DAW — so when a cable gets kicked or macOS reshuffles your devices mid-show, nothing drops. No re-mapping. No reset. No scramble before you go live.

It always happens at the worst moment.

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.

Keel keeps the connection your DAW depends on — even when the hardware doesn't.

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.

Keel does one job — and it's not audio routing.

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.

It just stays there

The device your DAW records and plays through is always present, whatever the hardware does.

Bit-exact, no latency tax

Keel mirrors your audio sample-for-sample on the interface's own clock. What goes in is what comes out.

Survives the unplug

USB drop, power blip, Core Audio re-enumeration — Keel rides it and hands back cleanly.

One device per interface

Mirror inputs and outputs; multi-interface rigs get a named, stable device each.

Set it once

No Audio MIDI Setup gymnastics, no reconfiguring before each service.

Made for the stage

Runs fully offline after activation. Whether you're capturing inputs or running backing tracks, the device never drops mid-set.

Who it's for

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.

Houses of worship

Multitrack capture and livestream off a Mac, week after week.

Backing-track & playback rigs

Ableton, MultiTracks Playback — click and stems out to FOH. The tracks never drop mid-song.

Live events & broadcast AV

When the DAW is in the signal path on stage or in the truck.

Livestream & streaming production

A DAW-based audio chain that can't drop while you're on air.

Recording & project studios

Long takes where a mid-session interface hiccup can't cost the take.

Proven in production

Multiple full live services. The DAW never lost its inputs or outputs.

Running on a real church rig — a 48-channel front end into PreSonus Studio One, livestreamed across multiple full services. One 11-hour continuous run held effectively zero clock drift (−1 ppm).

Questions

Will it change my audio?

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.

What happens when my interface disconnects?

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.

Which Macs and macOS versions?

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.

Does it work with my DAW?

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.

How is the trial limited?

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.

Do I need an internet connection?

No. Activation is a one-time step; after that Keel runs fully offline.

Is this like an audio-routing or virtual-cable app?

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.
