The Drive and Mix parameters can be modulated or automated with an external Control Voltage (abbreviated CV). The special signals needed for this are typically provided by analog synthesizers or specialized products for generating control voltages.
The CV can only cover the complete range of the Drive and Mix parameters if the corresponding knobs are set to their fully counter-clockwise position. Now you are able to control the parameters as follows:
The control voltages are fed into the karacter through the rearward EXT1 and EXT2 connectors. If the karacter operates in Link mode, both of its channels will be controlled by the signals present at EXT1.
