The Synthi AKS Matrix Interface is a complete interface unit for the Synthi AKS, or in other words, a ‘breakout’ box whereby the row/column signals of the matrix are taken out to 3.5 mm jack sockets. It allows very powerful interfacing possibilities for the Synthi AKS to external modular synthesisers and/or external effects racks. It is a unique device that really unleashes the power of matrix patching. All the signal/control inputs (right hand column of jacks) have 2.7k series resistors connected internally so taking signals in or out of the matrix using standard 3.5 mm mono jack plug cables via this breakout box gives the same attenuation as inserting standard matrix resistor pins.
Connection to external synthesisers is via standard 3.5 mm jack plug leads with the signal connected to the ‘tip’ of the plug. These connections also join the ground of the external equipment to the ground of the Synthi, which is important. Patches can be a combination of those created with patch pins, in the usual way, and jack leads from the unit to route Synthi AKS signals out to external equipment and send external signals (such as waveforms, envelopes, filter out, effect etc.) back into the matrix.
In this way the unit can act as a unique interface, leading to a powerful symbiosis of Synthi AKS sounds and external modular synthesisers and signal processing equipment.
