The MINI MATRIX is an excellent way to economically connect together all the modules. Based on the matrix of the ‘Putney’ VCS3 synthesiser designed by EMS. The left vertical row contains six inputs normalised to six DC accurate buffers and the top horizontal row contains six outputs. Redundancy is a method of increasing functionality by reducing the number of connections. For example, using only one knob to mix two signals. The NODE PROC are manual/voltage controls that can be inserted to nodes in the MATRIX.
