left arrow - add a CCW motor at the mouse position

right arrow - add a CW motor at the mouse position

up arrow - reverse the rotation of the mouse-overed motor

delete or d - delete the mouse-overed motor

This tool lets you calculate mixer settings by simply measuring the distances between motors.After adding the necessary motors on the canvas, enter constraints for pairs of motors, and let the simulation run for a few seconds until the output values at the bottom of the page have settled. Click one of the example frame names to get an idea what this looks like.To add and delete motors, first click the main canvas to give it keyboard focus. Then you can use these keys:Ideally each motor should have three constraints. When three or more constraints are present the inner circle for that motor will turn green. Make sure to have at least one horizontal or vertical constraint to define the overall direction of the layout.For a demonstration of usage, see: this YouTube video
