Pin matrix explained

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 and the proximity of signal wires in the matrix can cause crosstalk.^[5]

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.^[6]
