Studio Electronics Boomstar Modular Sci Fi
SCI FI is a vintage-inspired ring modulation device. The SCI FI's ring-modulated signal is the sum and difference of the frequencies present in each waveform—a signal rich in partials—often producing a haunting, bell-like, metallic, and sometimes softly grinding, understated modulation awash in harmonic and non-harmonic tones. SCI FI is getting better all the time with its companion LFO FREQ (low frequency oscillator), true analog PINK, and digital WHITE noise, S & H—a true sample and hold generator, with RANGE control, and LAG generator—a slew limiter that evens out changes in audio or modulation signals. This module is every bit as creamy sounding as it is electrically charged.Potentiometer PotentialSix attenuation pots: RING MOD, LFO FREQ, WHITE, PINK, RANGE, and LAG.Patch it UpSeven patch points: RM X IN, RM Y IN, GATE, SOURCE, RM OUT, WHITE, PINK, and S & H OUT.
Studio Electronics Boomstar Modular SEM
The Boomstar SEM is known as a 'Voltage Controlled State Variable Filter' because it provides simultaneous high pass, low pass, and band pass outputs, all with a 12 dB/oct slope. The notch is the inverse of the bandpass, achieved by summing the low pass and high pass outputs. This version is a combination of the original SEM filter and the newer design from the OBX, along with improvements by SE. It has a modest current draw, which it pulls evenly from the plus and minus rails.This filter is a 'State Variable' circuit, which is an analog computer model of a pendulum. When the resonance is increased, the "damping" or stabilizing of the circuit is actually decreased. This makes the pendulum swing more wildly. If it is hit hard enough, it will swing all the way to one side and 'stick' there, what we call 'bonk out'. Many sound designers like the sounds that can be gotten as it goes into and out of 'bonk out', so Boomstar has not made the filter 'idiot proof' by limiting the input level and resonance amount. If you don't like it, limit your input level and/or resonance amount. Otherwise, go wild! It won't hurt the circuit. Potentiometer PotentialThree attenuverter and four attenuation pots control the FREQUENCY, RESONANCE, FREQ CV 1, RESO CV, LP HP, INPUT and OUTPUT, delivering smooth, detailed, and complex expression.Switch it UpFULL and HALF strength filter frequency keyboard/voltage tracking, and BP / LP-HP modes.Patch it UpSeven patch points: 1 V/O, FREQ CV 1, FREQ CV 2, RESO CV, INPUT, BP LP-HP, and OUTPUT direct the deepest manipulation.
Studio Electronics Boomstar SE80
The SE80 is the ultimate desktop analog synthesizer for those who remember the electronic Analog sound that changed the world, and for seekers who have yet to discover that magic in their time.Driven by rapid-fire hardware envelopes and Modular sound flexibility (at the flip of any of its 20 toggle switches), the BOOMSTAR® desktop synth is a performer and sound designer's dream. The Boomstar foundation: two Oscillators—stackable waveforms with Sub OSC, two Envelopes—invertible, loopable, with 'drone' and 'master' mode, is accented expressively by hardware XMod and exponential glide, extensive modulation routing, and a flexible software LFO: jacked for heavy lifting and fine-tuned experimentation—even go "off synth" with the external input and color exotic oscillations.The quick-turn shaft pots along the bottom for the hardware Ring Mod, Noise, Filter Feedback and VCO Levels make vital sonic change intimate, immediate, and indispensable; the adjacent Overdrive switch adds warmth and edge. Thirty one pots ensure fluid, intuitive mastery over wide-ranging sweep and subtlety of tone: feather in the changes or whip them suddenly and rhythmically into shape.S.

Studio Electronics Boomstar Modular Attenulag
Attenulag is a basic but indispensable through-hole synthesizer necessity designed and assembled in-house by our fine feathered friends at Boomstar. With it, you can augment efficiency and expressiveness starting with Boomstar’s handy R (Router) and ascending to its larger and more complex ATTENULAG companion for voltage-controlled switching, gliding, combining and amplitude limiting. ATTENULAG is a multi-purpose device. The attenuators reduce level, audio or CV when the switch is set to off. With the switch up, the audio/signal passes through at full level. The inputs are linked together: patching into channel 1 drives both attenuators; patching into channel 2 breaks the link. The two lag circuits provide a handy CV mult/hub for oscillator and filter tracking and are linked together: if you patch into channel 1 only, the outputs of both channels are drive; patching into channel 2 breaks the link and they become two separate CV mult/lag circuits. Four PotsATTENUATE 1, ATTENUATE 2, LAG TIME 1, LAG TIME 2. Four SwitchesOFF: the top two handle attenuation duties; the bottom are wired to lag time. Ten Patch PointsATTENUATE 1: IN, OUT; LAG TIME 1: IN, OUT 1A, OUT 1B, OUT 1C; ATTENUATE 2: IN, OUT; LAG TIME 2: IN, OUT 2A, OUT 2B, OUT 2C
Studio Electronics MODSTAR SLIMO
Featuring Identical OSCILLATION sound engine—the historic, stable and rich SE oscillator, slimmed down to 8hp essentials, with no tonal or quality sacrifice allowed; the SlimO is MidiMini big sonically. Compromise perfected. Three position octave switch is a bonus.
Studio Electronics Boomstar Modular SE88
The original CS80 fed an HP filter into a LP filter, but with the SE88 you can select MODE 1's HP or BR to feed MODE 2's LP or BP, or patch it to reverse that path. The audio signal is completely controllable with input and output levels for each filter. Cherish and respect your filter's input gain stages for a smooth yet often brassy sound, or shed your mercy for boiling, snarling bite, even to the blackout/cutout point; then blend the mode settings for the filter values you ultimately prefer.To get things modulating, each filter employs attenuverters for frequency and resonance experimentation and decimation. While the SE88 does not self oscillate (Yamaha's creation didn't either), Boomstar did amp up the resonance level for full-throttle squelching. An additional master FM (frequency modulation) attenuverter-controlled level can feed both filters simultaneously, and tracking switches allow for individual keyboard response for each of the contrasting and complementary filter modes.
Studio Electronics Boomstar Modular 3003 Filter
The 3003 filter is a voltage-controlled discrete analog 18 db/oct ladder low-pass filter that features hand-matched transistors. Drop the FREQUENCY knob to 0 and things get pretty dull; swing it back up and those "Transistor Bass” highs come crashing through the gate. This is a truly thrilling modular component.The 3003 filter has the most gentle sonic touch of its partners in the Boomstar collection, but nevertheless is capable of shaping precise, dynamic tones. It ably fulfills its expected niche, driving a harsh, liquid, acid-like bass tone or a softer more rubberry SH-101 voice. It excels out of the bass range and into blistering leads as well, all within easy reach of this warm and versatile VCF.

Studio Electronics Boomstar Modular 4075 Filter
The 4075 filter is a discrete, voltage controlled, 24/db/oct cascaded trans-conductance low-pass filter, that features six pairs of hand-matched transistors. In its lowest FREQUENCY setting, it shaves off higher frequency harmonics; its RESONANCE or “Q” circuit pushes those harmonics past the self-oscillation boiling point, projecting a thumpy, thrashing squeal with explosive low to mid-range power and depth. The 4075 is the most requested of the Boomstar filter models. It weaves dreams with “glidey” 70s basslines, and is a natural for leads. Aggressive and articulate, this fresh ARP can snap punishing kick drum sounds out as well as color with bright, edgy, string tones for essential arpeggiation.
