Tuner

Host or join
One bandmate hosts from their Mac. Everyone else types the server name and password, and they're in. No accounts, no subscriptions, no server to rent.


Plug-ins and instruments
Load the Audio Units you use in Logic, or VST3. Play software instruments like Serum from your MIDI keyboard. Everything runs on your Mac, so your bandmates hear your plug-ins even if they don't own them.

Logic-style mixer
Setting, EQ, Input, Audio FX, Sends, Output, pan, fader, mute and solo, laid out the way Logic Pro does it. If you've mixed in Logic, you already know how to use it.

Personal mixes
Turn the drummer up in your headphones without changing a thing for anyone else. Each bandmate is a channel strip on your mixer, with its own EQ, plug-ins, fader and pan.


Channel EQ
Low Cut, Low Shelf, four parametric bands, High Shelf and High Cut. Drag the nodes, scroll for Q, double-click to switch a band off. Click the EQ thumbnail on any channel strip to open it.

Practice tools
The little things that keep a band together, built in.
Press ⌘ U and tune the selected track's input, right in the middle of the jam.

Every player, their instrument, their codec and how far behind you they are, live.

A metronome synced to the host's clock, so the click lands at the same moment for everyone. Plug-ins follow the tempo too.

Hit R to capture exactly what you hear as a 24-bit WAV, ready to drag into Logic.
⌥ L bypasses any plug-in that adds delay. The bypassed slots turn orange, just like in Logic.
No keyboard with you? ⌘ K turns your Mac keys into notes, with Logic's layout.
Call the next song, the key or the tempo without stopping to talk over the music.

Save your whole guitar chain once, then load it on any strip, any session. Copy and paste strips like in Logic.
How it works
Every millisecond is accounted for, from your interface to their headphones.
One player clicks Host and picks a server name and password. Their Mac becomes the meeting point.
Bandmates nearby type the server name. Everyone else pastes the invite code, which starts with RW-.
Start the click, set your mix, and go from the top. Everyone hears everyone, with their own plug-ins on.
Audio leaves your Mac in 2.5 ms frames over UDP, marked for priority on routers and Wi-Fi.
The host forwards each player's audio the moment it arrives. No server-side buffering at all.
Each bandmate's buffer adapts to their connection and shrinks again when the network settles.
Everyone syncs to the host's clock, so the shared click and tempo-synced plug-ins stay locked.
Download RehearsalWare, send your bandmates the link, and rehearse tonight.
