Pin matrix

Routing matrix of an EMS VCS3 synthesizer. source ↗

The Pin matrix is a compact and visual to way to semi-permanently route signals or program devices, such as in early digital electronics¹² or lighting control boards.³⁴

Disadvantages

The number of patches that can be made is limited⁵ 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
