Erica synths Bullfrog Electric Organ Voice Card

The Bullfrog Electric Organ Voice Card is a card for Bullfrog offered by the Erica Synths brand.

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

The electric organ voice map for the Erica Synths Bullfrog combines the square waveform of the oscillator with the divider and adds the frequency dividers and its own volume controls. This emulates the technical concept of an electric organ from the late 1960s, a pipe organ, when multiple notes with octave intervals are played together.
