**grandMA3 onPC** is the grandMA3 console software for Windows and Mac. MA Lighting says it is the same software as on its consoles. To output DMX, you connect grandMA3 onPC hardware, such as a node or a command wing. MA presents it as an entry point for pre-programming and smaller shows. Showcaller AI sends commands to the onPC computer through the Bridge App. The [MA Lighting grandMA3 integration](/integrations/ma-lighting-grandma3/) page lists every function.

### Network setup for grandMA3 onPC

On a console, the show network is usually set up once. On a laptop, it takes a little more care. First, open Menu, In & Out, OSC, and turn on Enable Input. Next, pick the network interface on the show network in the same menu. A laptop often has Wi-Fi and Ethernet, so choose the one the Bridge App can reach. Then set up an OSC line for input with Receive Command on and an empty prefix. Finally, give Showcaller the computer’s IP address and the line’s port, 8000 by default.

### What you can send to grandMA3 onPC

The functions match the grandMA3 consoles. In every plan, Showcaller sends Go to a sequence or jumps to a cue. It also steps back, pauses a sequence or turns it off, and runs macros. With Pro, it sends Go or Off to an executor and sets its master fader. This is useful without a fader wing, because you name any executor by page and number. In addition, Enterprise adds the full command line.

### No reply from the software

OSC on the grandMA3 is one-way, because the software does not answer. So Showcaller reports a command as sent, not as done. Likewise, a page change or a fader move is not confirmed. Showcaller also asks you first before a macro, a command-line instruction or an Off command.
