Bullfrog is a classic subtractive synthesizer – it consists of several “modules” for sound generation – VCO, NOISE GENERATOR – and processing – VCF, VCA/DELAY, as well as “modules” that generate control and modulation signals to manage them – ENVELOPE GENERATORS and SAMPLE & HOLD. The Bullfrog will not produce 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 better 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 adapter
- User manual
- 10 patch cables
- 3 pre-patched voice cards: Sequencer, Acid Bassline, Sampler Looper
- 3 DIY voice cards
To provide a well-rounded understanding of the functionality of this synthesizer and sound synthesis in general, a comprehensive user manual is created to support the learning process.
