A SOUND SYSTEM 31 YEARS IN THE MAKING-
SENSEI ANALOG
SENSEI ANALOG is a lustrous, three discrete Oscillator, all analog duophonic dream machine (OK, our customized MIDI 3 is a clever forgivable digital necessity) which could, should, be thought in the same breath as celestial chariots of old—here transporting earthly creations beyond the hammered bowl/barrier of the firmament into a synthetic, sonic paradise. Four supreme, exalted filters... -
SENSEI HYBRID
SENSEI HYBRID resists analog purity for richly contrasting tones, modulation, and points of origin and purpose. Two stellar Eowave digital creations: the hypnotic and compelling CHARCOT CIRCLES: a 16 x 8 step sequencer, and STE. 16: a fiery, expansive, dual digital LFO, seem to have been waiting in the wings for just this moment to shine, as you might have guessed from their center-staging... -
SEITO RISING
Modstar Seito Rising 106 hp: MIDI 3 6hp, M (Multiple) 2hp, Oscillation (x2) 32hp, 4075 12hp, M 2hp, Levels 10hp, Sci-Fi 10hp, Shapers 12hp, Amp 8hp, LFO 2 6hp, Outs 6hp. Housed in a sleek and sturdy, carbon-fibre black MONOROCKET M6E case - a superbly well powered and constructed Eurorack enclosure... -
3003 Filter
The 3003 filter is a voltage controlled, discrete analog 18 db/oct ladder low-pass filter, employing 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. The 3003's RESONANCE circuit at max will sing out more than the TB’s signature chirping... -
4075
The 4075 filter is a discrete, voltage controlled, 24/db/oct cascaded transconductance low-pass filter, employing 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... -
5089
The 5089 filter is a voltage controlled, discrete analog, 24 db/oct transistor ladder, low-pass filter, employing hand-matched transistors. Our ladder low-pass filter—a subtractive analog sound synthesis foundation—in its lowest FREQUENCY setting removes, or cuts off higher frequency harmonics... -
8106 FILTER
Tim Caswell's Jupiter to Juno filter take: "The 8106 is a 6db/oct hi-pass filter followed by a recreation of the Roland IR3109 module, which is a 4 pole, 24 db/oct voltage controlled lowpass filter with voltage controlled resonance. Three dual OTAs with similar topology to the BA662 used in the Jupiter 8 (and the IR3109 module) were employed... -
AMP
The amplifier (AMP) is a 2 stage Class A discrete design using 3 pairs of hand matched transistors. Envelope is usually applied to ST1/1. ST1/2 goes thru an attenuverter and can be used for envelope or modulation. ST2/1 goes to the 2nd stage, and is typically used for modulation... -
CHARCOT CIRCLES
Surrender yourselves to the hypnotic, borderline hysterical sway of the CHARCOT CIRCLES (named for Jean-Martin Charcot* "founder of modern neurology”) to awaken your mind and muse. Only the C. C. possesses the organic power and intelligence to identify specific sites in brain responsible for detailed, sequential, musical functions... -
GRAINY CLAMPIT
GRAINY CLAMP-IT is a granular and phase distortion additive oscillator—brand new heavy territory for Studio Electronics... we know; wait till you hear the stunning contrast it creates when paired with our discrete Class-A OSCILLATION module, and the inorganic to downright 1970's combo organy / CS-80-ish tones it can generate. Pure voltage-controlled candy... -
LEVELS
LEVELS is a versatile, low-noise six channel summing mixer/attenuator for audio and CV, re-designed by Tim Caswell, which can be used rather effectively in a variety of ways: 6 in 1 out, or two separate mixers: 4 in 1 out, and 2 in 1 out, e. g., when only jacked-in to MIX 5/6 output all input channels pass through... -
LFO 2
LFO 2 is a basic dual LFO module. It uses two different types of low frequency oscillator circuits to provide a variety of modulation options. LFO 1 - A triangle based low frequency oscillator that utilizes rate and symmetry controls to generate shifting waveforms. Adjusting the symmetry control varies the shape of the TRI output from sawtooth to triangle to ramp... -
MIDI 3
The MIDI 3 is Pittsbutgh Modular's third generation extremely full-featured MIDI to CV converter, optimized by Tim Caswell for the Boomstar Modular system. It includes a complete set of mono and duophonic midi response modes, assignable CC and dedicated velocity outputs, a feature rich clock source with tap tempo, midi and external gate clock dividers... -
MULTIPLE
A passive utility module with two independent sections of four linked jacks. Each section of the MULTIPLE module splits an incoming signal into three copies. This allows one audio or CV signal to be sent to several destinations at once.... -
OSCILLATION
At the beginning of the tone parade, we cheer on another cagey Tim Caswell hybrid, which utilizes an exponential current source in a sympathetic spirit, to the through-hole, glory days circuits of ARP and Oberheim, followed in perfect sync by wave shaping circuits adapted from 2nd generation Minimoog Model D oscillator boards, and an incorporation of waveform mixing circuits... -
OUTS
The simplest way to get sound out of a modular—so our good friends at PGH tell us. OUTS is a dual independent output module featuring a stereo 1/4" headphone amplifier output and dual mono 1/4" line level outputs... -
QUADNIC
QUADNIC reps. our 2nd collobaration with SpaceHardware—a deeply featured 12hp module with four digital oscillators—each with a selection of 64 waveforms, 7 different processing modes including phase distortion and wave sequencing, and a dedicated volt per octave input. In unison mode, all 4 OSCs can be played via the 1st 1V/O CV input and widely detuned, or switched to a preset chord formation... -
SCI FI
SCI FI is an ingeniously vintage-circuit-inspired Richard Nicol/Pittsburgh Modular original. As the reader might already know, ring modulation is a signal-processing electronic function: an implementation of amplitude modulation or frequency mixing, performed by multiplying two signals. This beloved other-worldly, warm, and often clangorous coloring, dates at least as far back to Bode's 1947 Melochord... -
SE88
Our version of the boxy, Blade Runner-sweet and Boomstar-brash dual mode CS80 filter, initially married to the Omega Series Synths, and then tucked-in the 'Stars, now joins the Modstar Collective. We've twisted and turned the SE88 to unflatten the earth, so to speak; the original CS80 fed a HP filter into a LP filter, but with the SE88 your can select MODE 1's HP or BR to feed MODE 2's LP or BP... -
SEM
Sensei Caswell: "Our 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..." -
SHAPERS
SHAPERS is a dual four stage envelope generator with independently adjustable ATTACK, DECAY, SUSTAIN, and RELEASE stages. Our Pittsbutgh Modular hybrid ADSR smooths the shape of the incoming gates and triggers to produce a more expressive instrument, just like its antecedent. The ADSR output can be used to control the amplitude of an oscillator... -
SLIMO
Identical OSCILLATION sound engine—the historic, gorgeously stable and rich SE oscillator, slimmed down to 8hp essentials, with no tonal or quality sacrifice allowed; the Slimo is MidiMini big sonically. Three position octave switch is a bonus.... -
STE. 16
The STE. 16 (our second collab. with eowave designer Marc Sirguy), is a dual LFO, featuring a HI-freq mode and complex waveform mixing possibilities, which thinks nothing of producing thousands of different modulation and audio frequency shifts and wiggles. In fact, it doesn't think at all—well maybe it does. The STE's amplitude modulation, frequency modulation, and waveform mixing... -
UTILITY - ATTENULAG
Multi-purpose heavy lifter. The attenuators reduce level, audio or CV, when 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. Experimentation with key tracking to create alternative tunings... -
UTILITY - MIX4
Space conscious, 4 in/1 out, high quality audio and CV mixer. Originally set at unity gain (along with the VCA2), but tinkering provided useful intell and design changes. Upshot: With the pot set at 3:00 you are at unity, fully clockwise, expect a 2 Volt increase... -
UTILITY - R (ROUTER)
Two audio or CV routers—bi-directional—despite what the nomenclature states. Bring a signal in and switch between two desirable destinations. Center off switch. Great for instantaneous audio or CV effects: flip your wilson between polar opposites, or subtly nebulous contrasts with your fingers... -
UTILITY - VCA2
Two quality VCAs for audio or CV with level control—advantageous for creating a CV modulation chain: Patch the 1st (controlling) modulator into the CV input, and the 2nd and 3rd (the controlled) modulators into inputs A and B; the output can then be patched to a modulation destination such as an oscillator or filter frequency. The same approach is effective for enveloping an LFO...
