Algo Expander for Quad Opreator - DX Style FM Synth

4HP 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

• Firmware upgradeable

• Humble Audio products are warranted for 12 months from date of purchase
