Bullfrog is a classical subtractive synthesizer – it consists of several “modules” for sound generation: VCO, NOISE GENERATOR

... And treatment: VCF, VCA/DELAY

... As well as “modules” that generate control and modulation signals to control them: ENVELOPE GENERATORS and SAMPLE & HOLD.

The Bullfrog will not make the sound on its own unless it is patched – using eurorack patch cables to interconnect the “modules” or by inserting voice cards that create internal connections between the “modules” in a specific way and add extra functionality, like sampler/looper, sequencer, groovebox, etc.

This approach better helps to understand the functionality of a subtractive synthesizer and the principles of sound design with instruments like these.
