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.

Sharp-dressed and snappy, single or multiple triggering (VCA 2), envelopes hearken back to our MIDIMINI roots; drone and master modes update the tech.
All discrete circuity, with our trademark hand matched transistors in the filter and amp.
Control Voltage, Gate, and External input connectivity for old school interfacing, speed, MIDI freedom, and external source processing flexibility.
1. Refaced for clarity of function, signal flow and an overall visual/tactile assist.
2. Revoiced for purity of tone—more headroom into amplifier; browning-out is delayed.
3. Diode-based feedback circuit for greater dynamic range and harmonic distortion content. under control v0122a by slusiom

Slusiom maintains a highly active development cycle, primarily supported through Patreon, where subscribers gain early access to new versions and exclusive 4K renders. The developer has also launched a dedicated Slusiom Launcher to streamline the installation and update process for players.
While the specific changelog for is typically exclusive to development platforms like Patreon, Slusiom’s update history suggests a focus on refining character interactions and expanding current events. Based on previous builds like v0.1.18a, updates generally include:
: Expanded missions or intimate scenes for primary characters such as Cynthia, Tamara, or Veronica.
: Updates often bring new interfaces, such as inventory screens or main menu background animations.
The plot of Under Control places players in a world where time management and skill development are crucial. As you navigate the protagonist's new life, your decisions directly impact your relationships and the eventual outcome of the story. The game transitions from a slice-of-life exploration into a more complex thriller as "dark secrets" begin to condition the environment and characters around you. Key gameplay features include:
