The **grandMA3 light** is the work-horse of MA Lighting’s grandMA3 range. MA lists 15 motorized faders, 60 separate playbacks and 16 assignable x-keys. It also has two letterbox screens, one fewer than the full-size. MA rates it for all but the most demanding productions, with 16,384 parameters. Showcaller AI sends commands to the console through the Bridge App on your network. So the lighting desk can take cues by voice or chat. The [MA Lighting grandMA3 integration](/integrations/ma-lighting-grandma3/) page lists every function.

### Beyond the 15 faders

On a grandMA3 light, a show often spreads across several executor pages. Showcaller does not need the executor on a physical fader. Instead, you name the page and the executor number. As a result, the physical faders stay free for the operator. For example, ask for Go on executor 201 on page 3, or its master fader at 60 percent. You can also switch the active page by voice. These executor and page functions come with the Pro plan. Meanwhile, sequence playback and macros come with every plan.

### One-way commands on the grandMA3 light

Showcaller uses the console’s OSC input. However, the grandMA3 does not answer OSC commands. So Showcaller reports that it sent a command, not that the console ran it. That includes page changes and fader moves. In practice, the operator watches the desk, as with any one-way remote. Before the show, run a quick test cue to check the OSC line.

### Sequences, macros and confirmations

In every plan, Showcaller sends Go, Go+ and Go- to a sequence. It also jumps to a cue number, pauses a sequence or turns it off. For example, ask for Go+ on sequence 1 to step to its next cue. Macros run by number, and Enterprise adds the full command line. Still, Showcaller asks first before a macro, a command-line instruction or any Off command.
