Hold to talk in the browser app on your phone. Same session, same cues as the console.

Sync & export

Rename a cue in grandMA3, sync, and call it by its new name. Export the cue list as PDF or CSV.

Why Halo

Runs on your MacSpeech recognition runs locally. Your audio never leaves the computer.
Matches your show exactlyHaloSync sends the cue names from the show that is open. Halo only fires cues that really exist, and never guesses.
Never writes to your showThe plugin is read-only. It never stores, saves or edits anything in your show file.
Stand by, then GoThe big amber STANDBY bar shows what is armed before you fire it, on the Mac and in the browser app on your phone or tablet.
Call cues by nameSay a cue by its name or number, before or after the word Go.
Safe by defaultHalo starts in Dry run, so nothing reaches the console until you turn it on.
Cue TrackerAn optional window, off by default. See the current and next cue across several playing sequences, live from your show.

Halo in the browser

Turn on Phone remote in Halo's settings and open the browser app on a phone, tablet or laptop on the same network. It is off by default, works on your local network only and is protected by a PIN.

Same voice commandsHold to talk and call cues the same way you do on the Mac, or type a cue or command.
STANDBY cardThe amber STANDBY card shows what is armed before you press GO.
Confirm or CancelCommands that need a check ask first, with Confirm and Cancel buttons.
Cue Tracker panelTurn on the Cue Tracker panel in the settings sheet to see current and next cues.

Set up in five steps

InstallOpen the BDM Halo disk image and drag Halo into Applications.
Open it the first timeHalo is not notarized by Apple yet, so macOS asks once. macOS 15 Sequoia or later: double-click Halo, click Done, then System Settings > Privacy & Security > Open Anyway. macOS 14 or earlier: Control-click Halo > Open > Open. Step-by-step guide
Import the HaloSync pluginCopy HaloSync.xml and HaloSync.lua from the MA3 Plugin folder into your grandMA3 plugins folder, then import HaloSync.xml into an empty Plugins pool slot.
Connect to grandMA3In grandMA3 (Menu > In & Out > OSC) turn on Enable Input and add one line that receives Halo's commands: UDP port 8000, Receive and Receive Command on. In Halo set the console IP (127.0.0.1 when onPC runs on the same Mac) and port 8000. Same Mac: that is all, cue names come back automatically, so do not add a line back to Halo. Console on another computer: also add a send line to the Halo Mac on port 8001 and start the plugin with Plugin "HaloSync" "osc=8001".
First syncRun Plugin "HaloSync" in grandMA3 and press Sync now in Halo. Your cue names show up, ready to call. Turn off Dry run when you are ready to drive the console.
