Erica Synths Bullfrog Sequencer Voice Card is a compact sequencer for your Bullfrog.
Voice Cards extend the functionality of your Bullfrog synthesizer, making it even more versatile. Some replace patch cables by internally connecting Bullfrog "modules", others include built-in mixers, signal generators and advanced electronics to control the synthesizer. For example, the Sequencer outputs CVs for pitch control and gates for triggering events, while the Sampler/Looper emulates the functionality of a reel-to-reel tape recorder.
The Bullfrog Sequencer Voice Card is a compact 5-step CV/Gate sequencer for your Bullfrog. It generates up to five steps of discrete control voltages to control the pitch of the VCO and gates to trigger the envelope generators.
