Boomstar is a return to the raw power and purity of non-programmable discrete analog, where STUDIO ELECTRONICS started in 1985. The snap and punch of hardware envelopes drive the Boomstar's brilliant discrete voltage controlled circuits with unparalleled sonic clarity and versatility; refaced, and revoiced, the Boomstar MKII is likely the ultimate desktop analog synthesizer for those who remember, and desire still, analog synth sounds that changed the music, and sound seekers who have yet to discover that electric magic and delight in their time—via MIDI or CV of course. The Boomstar's alchemy of combinable waveform oscillations—with sub, OSC1-OSC2 sync—filter and oscillator xmod, ring mod, 5 revered filter types, extensive modulation routing made easy via its 18+ toggle switches, and a flexible software LFO, make sound and music design a daring delight. Hardware envelopes with invert, loop, drone and master mode deliver that flexible, funky snap and shift. The quick-turn shaft pots along the bottom for the hardware ring mod, noise, and feedback are diode-based for more complex and interesting harmonic distortion, and VCO Levels make vital sonic changes intimate, immediate, and indispensable; the adjacent overdrive switch adds beefy boost, warmth, and edge. 29+ pots ensure a fluid, intuitive groove over wide-ranging sweeps, and subtle tone variations: whip them suddenly and rhythmically into shape, or feather in the changes. Expect cleaner levels in and out of the 5 MKII filter models (MKIIs will still brown out but their headroom is more generous). Can't decide which model deserves your attention? It does help that Boomstar is a discrete, through-hole, hand-matched transistor, semi-modular desktop monophonic synthesizer, built in the U.S.A. to last, no matter which glowing circuit, handcrafted filter model you choose—the first time.
