Notes: 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 Gesture Controller voice card gives a new type of control over the Bullfrog, allowing for it to be played like a Theremin, with some handy extras. The PITCH and VCA/VCF sensors of the Gesture Controller are internally routed to the VCO pitch and VCA level/VCF cutoff parameters of the Bullfrog once connected. The card also features a built-in pitch quantizer that can be turned on or off as desired, an adjustable pitch range for the sensors (1V, 3V or 5V) and another toggle switch for an additional internal connection which allows for sending gates to the Bullfrog's EG's from the VCA/VCF sensor. Besides the internal connections, the card also has separate outputs for PITCH CV and VCA/VCF CV from the sensors that can be patched elsewhere.
