Where it goes on stage
Where it sits on the deck changes how the rest of the plot reads. Keyboard rigs sit stage left or stage right with the player facing across the stage, so they can see both the drummer and front of house without turning their back on the room. Snap the icon to the grid and the distances stay believable on a printed page.
What the crew needs to know
Say this part explicitly. Confirm stand type and whether the rig is single or double tier. Height changes the sightline for everyone behind it.
On the input list
Keytar is a stereo source, so it produces 2 channels on the input list, L and R. Both default to a DI input, no stand and phantom power off. It sorts at position 5 in the drums first, vocals last channel order that front of house engineers expect.
Console exports
Because the input list is generated rather than typed, it exports straight to console: X32 and M32 scene files, Wing scenes, and CSV channel names for the Allen and Heath, DiGiCo, and Yamaha families. See the console guides.
