The Pin matrix is a compact and visual to way to semi-permanently route signals or program devices, such as in early digital electronics^[1][2] or lighting control boards.^[3][4]

Disadvantages

The number of patches that can be made is limited^[5] and the proximity of signal wires in the matrix can cause crosstalk.^[6]

Synths that have used a pin matrix

Also known for being used to patch (program) some synthesizers. Generally inputs are on one axis and outputs on the other and a pin inserted where the two axes meet establishes a connection.^[5]
