GrandMA3 Setup Guide

CueSync speaks to GrandMA3 natively — it sends real console commands over the network, pushes your cue list to a desk sequence, and can read the desk back. That native path is desk-verified against grandMA3 2.3.x and 2.4.2 and is the one to use. (Driving GrandMA3 with raw Art-Net DMX is also possible but experimental — see the last section.)

Prerequisites

• GrandMA3 console or GrandMA3 onPC on the same network as your Mac
• Every CueSync edition includes GrandMA3 output; Session Sync (cue-list push/pull) is a Theatre/Production feature
• Ethernet strongly recommended

Step 1: Add the GrandMA3 Output in CueSync

1. Go to Network → Outputs → + and add a GrandMA3 (UDP) output with your console's IP address. UDP is the recommended transport — current consoles don't open an OSC-over-TCP listener, so a TCP output may never connect.
2. Confirm the output shows connected.

Step 2: Let the Console Accept Commands

On the console, open the OSC line settings and enable both Enable Input and Receive Command. Without Receive Command the desk silently ignores every command CueSync sends — this is the most common configuration error.

Step 3: Fire the Desk from CueSync

• Looks — build GrandMA3 Looks on the Looks screen and fire them from pads, cues or Auto Pilot; CueSync resolves each Look to the matching console commands.
• Cue actions — attach GrandMA3 actions (Go, executor, macro commands) to any cue in your stack, triggered by beat, phrase, timecode, or manually.

Step 4 (Theatre/Production): Session Sync

File → Sync to GrandMA3… moves your whole Theatre cue list to the desk without re-programming:

• Push your cue structure into a scratch sequence (900/950/999) — the dialog previews every command and never re-stores existing cues, so the looks your LD programmed survive a re-push.
• Export as an MA3 macro or Timecode XML to carry the show on a USB stick when there's no network to the desk.
• Install the read-back bridge (a read-only Lua plugin) to get drift warnings and pull the console's cue list back into CueSync.

Troubleshooting

Alternative: Art-Net DMX (experimental beta)

CueSync can also output raw Art-Net DMX for GrandMA3 to receive as a DMX input source. This path is experimental and not yet verified on hardware — prefer the native output above for show use. If you need it (e.g. to feed executor faders as DMX remotes), see ArtNet Configuration.
