dynamically controlled multi-output mixing module controlled by the MS-MATRIX module via MIDI.

The Alyseum MS-VCA4I & MS-VCA4O are two dynamically controlled, multi-input and multi-output mixing modules controlled by the MS-MATRIX module via MIDI.

The MS-VCA4I adds mixer functionality and increases the number of inputs available on the MS-MATRIX, whereas the purpose of the MS-VCA4O is to add mixer functionality and increase the number of available outputs on the MS-MATRIX.
Of course both the MS-VCA4I and MS-VCA4O can act as standalone modules, but why miss out on the power of MIDI connectivity and the unique preset functionality that their combination with an MS-MATRIX provides?

Up to eight MS-VCA4I and MS-VCA4O modules can work together via an IR link connection, creating a powerful behemoth of immense functionality for your Eurorack system.
