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.

What’s included:

BULLFROG synthesizer
Universal 12VDC wall wart adapter
User manual
10 patch cables
3 pre-patched voice cards: Sequencer, Acid Bassline, Sampler Looper
3 DIY voice cards
In order to provide a well-rounded understanding of the functionality of this synthesizer and sound synthesis in general, a comprehensive user manual is created to accompany the learning process.
