Expand the functionality of your synth with the Erica Synths Acid Bassline Voice Card, an expansion card for the Bullfrog synthesizer that instantly provides you with all the necessary connections to produce a punchy bassline.
With the card inserted, the synthesizer utilizes an external controller (MIDI keyboard, MIDI sequencer, or CV/gate sequencer) to trigger the synth engine. All audio sources—Sine Out, Pulse Out, and Noise—are mixed and sent to the VCF and then to the VCA. A gate starts both envelope generators; the EG 1 controls the VCA, while EG 2 controls the cutoff of the VCF. In addition, the S&H output controls the waveshape of the VCO.
