Algo Expander

Expander for Quad Operator's algorithm functionality. Where the unexpanded Quad Operator maintains a one knob per function design discipline, we nevertheless recognized the value of some more advanced algorithm-oriented functionality.

The Algo expander for the Quad Operator provides
• Saving and loading of modulation send knob positions for FM algorithm design reuse
• Crossfade between pairs of saved algorithms, or a saved algorithm and the live knob positions

In the Box
• The module itself
• Eurorack Power Cable
