Voice cards expand the functionality of the Bullfrog and make it even more versatile. Some voice cards replace patch cables - they connect the "modules* of the Bullfrog internally, while others have built-in mixers, signal generators, and advanced electrical circuits to control the synthesizer, for example, the Sequencer sends CV to control pitch and gate to start events on the synthesizer and the Sampler/Looper emulates reel to reel tape recorder functionality.

The WIND AND STARS (NOISE) voice card makes internal connections of the Bullfrog so that it automatically emulates randomly evolving wind sounds and blinking stars are controlled by the divider. Toddlers fall asleep better when they hear sounds like these. 

Refer to the Bullfrog User Manual for more information on the voice cards.
