The Erica Synth Bullfrog is a collaborative endeavour between Erica Synths and Richie Hawtin. It represents an exceptional educational electronic music instrument meticulously crafted to captivate and inspire users, irrespective of their experience level. Its central mission revolves around seamlessly merging the allure of electronic music production with a comprehensive and enriching learning experience.

At the heart of the Bullfrog's capabilities lies its fully analogue design, assuring that every sonic output resonates with authenticity and depth. Whether you're a newcomer to the world of electronic music or an accomplished professional, the instrument's highly precise voltage-controlled oscillator (VCO), spanning an impressive 8 octaves, is a testament to precision and versatility in sound generation.

The Bullfrog empowers musicians and enthusiasts with unparalleled control over their sonic landscapes. Through manually adjustable and voltage-controlled waveshapes, including the distinctive sine-shark fin and pulse wave with pulse width modulation (PWM), your creative sonic explorations are boundless. Moreover, a Zener diode-based noise generator and a resonant lowpass voltage-controlled filter (VCF) provide the tools to craft intricate and textured soundscapes.

Bullfrog offers an array of features for those inclined to infuse their musical compositions with nuance and depth. A voltage-controlled amplifier (VCA) with adjustable offset and the capacity to delve into delay effects, featuring customisable delay time and feedback, are readily available. The instrument boasts two looping attack-sustain-release envelope generators (EG), granting you precise control over the dynamics of your sound.

Bullfrog incorporates a dedicated Sample & Hold circuit equipped with an individual clock to elevate your sonic journey to new heights of complexity and intrigue. Real-time sound manipulation becomes effortless with a manual gate button, allowing for on-the-fly creativity and experimentation.

The Bullfrog's expandable nature unlocks doors to limitless creative possibilities. Featuring a voice card slot and complemented by a built-in speaker for on-the-go musical exploration, it facilitates adventures beyond the ordinary. Furthermore, the instrument seamlessly integrates into your existing music setup with DIN5 MIDI input and a USB connector, enhancing its versatility and adaptability.

Compact and portable, Bullfrog's dimensions (40 x 385 x 210 mm) and weight (1.8 kg) render it an ideal companion for music creation, wherever and whenever inspiration strikes.

Fundamentally, Bullfrog operates as a classical subtractive synthesiser, consisting of various "modules" for sound generation (VCO, NOISE GENERATOR) and sound treatment (VCF, VCA/DELAY). Additionally, it includes "modules" dedicated to generating control and modulation signals for these components (ENVELOPE GENERATORS and SAMPLE & HOLD). It's crucial to note that Bullfrog does not generate sound until these "modules" are connected, either through eurorack patch cables or by inserting voice cards, which create internal connections between the "modules" in predetermined ways, offering additional functionalities such as sampler/looper, sequencer, or groovebox. This approach enhances comprehension of subtractive synthesizer functionality and sound design principles.
