DAWperator streams bit-exact audio and syncs transport between DAWs running at the same time on your Mac — a native Apple Silicon way to get the job ReWire used to do.
No cables, no drivers, no routing software.
Run the installer and restart your DAWs. Look under the manufacturer L4Music in the plugin menu.
In the DAW that makes the sound, put DAWperator Send on a track. Its audio is published on one of that DAW's 16 buses.
In the DAW that collects it, add DAWperator Receive, turn the DAW knob to the sender and pick the bus. Record or mix it like any track.
At the same sample rate the audio arrives exactly as it left — every sample, in order. Tiny clock differences between DAWs are corrected automatically.
Every DAW gets its own 16 buses, so two DAWs can both use “bus 1” without clashing. Load several Receives in one DAW, each listening to a different DAW.
Play, stop, tempo and position follow across DAWs using MIDI Clock and MIDI Time Code on a virtual port, DAWperator Transport. Loops and locates follow too.
A stereo signal meter, buffer and latency readout, and a DAW list that greys out DAWs with no active Send — so you can see why something is silent.
Apple Silicon Audio Units, lock-free shared memory, nothing running in the background. Signed and notarized by L4Music.
14 days free, then one purchase covers 2 of your Macs for good. Free updates for the whole 1.x series.
Pick the sending DAW and bus, watch the signal, trim the gain.
Tested with Ableton Live 12 and Fender Studio Pro 8. DAWperator is a standard Audio Unit, so it is built for any macOS DAW that hosts Audio Units; the sending and receiving DAWs can be different apps. Apple Silicon only.
One-time purchase. No subscription.

No. It does the same job — moving audio and transport between DAWs running side by side — but it is a new, native Apple Silicon plugin, not the original ReWire protocol (which was Intel-only and has been discontinued).
In the sending DAW, DAWperator Send on a track. In the receiving DAW, DAWperator Receive on an instrument track. For transport sync, run DAWperator Transport (or the one-plugin DAWperator) in the DAW that leads, and set the other DAW to follow the DAWperator Transport MIDI port.
About the combined buffer size of the two DAWs plus a few milliseconds of safety buffer (adjustable). The Receive panel shows the current figure. Use small buffers in both DAWs to keep it low.
Yes, when both DAWs run at the same sample rate: samples are copied exactly. If the clocks differ slightly, or the sample rates differ, DAWperator resamples gently to keep the streams locked, and that audio is no longer bit-for-bit identical.
Yes. Add one DAWperator Receive per source in the receiving DAW and point each at a different DAW. Each DAW has its own set of buses, so there are no clashes even if every Send stays on bus 1.
The first use starts a 14-day trial. After that, enter your license key (click ENTER LICENSE in any DAWperator window). One key activates 2 Macs, and you can deactivate a Mac to move the license. If you are offline, an activated license keeps working for 30 days.
Apple Silicon Macs (M1 or later) on macOS 11 or later; tested on macOS 26 Tahoe. Intel Macs are not supported.
Download the installer, restart your DAWs, and look under L4Music.
