Switches and combines different input channels to different outputs.

The 4x4Matrix, 8x8Matrix and 16x16Matrix contraptions let you dynamically route signals without repatching the document. Each input can be routed to any combination of outputs. More than one input can be connected to an output at the same time. In this case, the signals are mixed together. When an input is switched on to an output it is faded in, and faded out when you switch it off. The time taken to fade in and out can be controlled.

See the Adjusting Contraption Properties section for information about using sliders, knobs, presets etc.

Matrix parameter editor window


Creates connections between different inputs and outputs. Each input is represented by a horizontal row, and each output by a vertical column. Click on cells to toggle connections between specific inputs and outputs.

Fade time


Determines the time taken for a newly connected input to be faded into the output, or a disconnected input to be faded from the output. FadeTime can range from 0 ms to 100 seconds (100,000 ms).

Use short values of fade time to prevent clicks when switching, and longer fade times to create slowly fading mixes.
