Created by Erica Synths & Richie Hawtin, the Bullfrog is an educational electronic music instrument designed to captivate and inspire.
It is a classical subtractive synthesiser consisting 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 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 helps to understand the functionality of a subtractive synthesiser and the principles of sound design with instruments like these.
