IMPORTANT INSTRUCTIONS - PLEASE READ

! ! !

Please read the Boomstar Modular Synthesizer Manual completely before use, and retain for future reference.

IMPORTANT Ribbon Cable Power Information:

Boomstar Modular combines a set of individual modules to create a complete instrument. The individual modules can be rearranged, removed, and replaced with any compatible eurorack modules from Studio Electronics and other manufacturers.

Boomstar Modular uses a standard eurorack power rail to connect the modules to the internal bipolar +/-12v power supply. Please pay very close attention to the orientation of the ribbon cable when adding and removing modules. The stripe on the ribbon cable marks -12v. This stripe needs to line up with the -12v pins on the power rail and the -12v pins on the module. Failure to match up the pins correctly can result in damage to one or all the modules in the Boomstar Modular. On the power rail, the -12v pins are clearly labeled. On the individual modules, the positive and negative sides of the pin connectors are labeled next to the power header on either the top or bottom of the PCB.

Do NOT remove individual modules from the Boomstar while synthesizer is plugged in.

NEVER unplug ribbon cables from the Boomstar Modular, or any other modules while the Boomstar Modular is plugged in.

Boomstar Modular Introduction

THE BOOMSTAR MODULAR SYSTEM realizes the seemingly inevitable!eurorack sprawl of our semi-modular BOOMSTAR desktop synth, consisting of 14 modules that dramatically open up the root level programming and sound sculpting of that lush, potent, and fantastically flexible multi-filtered Boomstar sound.

What makes it tick: Let’s tick ‘em off: Class A 5089, 3003 and AMP *, rugged through-hole construction, discrete circuitry, hand-matched transistors in the filters and amplifier, multi-filtered, hand-crafted, Premium Quality Analog sound. We’d like to think we’ve learned a few things bringing the MIDIMINI, SE1-X, ATC-X, polyphonic CODE OMEGA synths, MODMAX PEDALS, C2S, PRE 2, and SLATE PRO AUDIO DRAGON and FOX to market, and the air waves worldwide.

Our Boomstar Modular System’s (Modstar) 5089 circuit mirrors faithfully the filter design from the Minimoog—it is not a style; it’s not a type, not reminiscent of, not vintage inspired—it is the analog sound standard manufactured anew, and how we love it so. Apply the same thinking to our 4075, 3003, and SE80 filters vis-à-vis their originals, and you’ve caught our drift; the OSCILLATION and AMP modules also resonate with the Mini’s timeless designs, functionality, and gorgeous, gleaming sound— modernized and reimagined by the maestro Tim Caswell himself, but we’re just getting started here; the SEM filter is on deck.

We hope you are as thrilled with your purchase of the complete system/individual modules as we are with our partnership with PITTSBURGH MODULAR, and the final highly collaborative through-hole designs which flowed from the first Nicol/St. Regis Beer Summit at Winter NAMM ’13. The MODSTAR module breakdown upshot: Filters, Oscillators, and AMP are built by SE, and the intoxicating remainder by our good friends and exceedingly savvy business partners at PGH—without whose invaluable, real world/walking the streets of Euroland insights, experience, and deep resources, this project would have faded to grey. A tip of the SE chapeau to Richard Nicol, Perry, and the full-strength, generally less-weathered outfit at P. M. AND to Geoff Farr who relentlessly hounded the St. Regis bros—“When are the euro modules going to be ready?” Looks.

Modular Signal Paths

(Copy courtesy of Pittsburgh Modular)

The BOOMSTAR MODULAR’S signal path is divided into two types of signals: audio signals and control voltages.

The audio signal is the sound that is produced. The audio signal path starts at a sound source such as a Waveforms oscillator, LFO running at audio rate, or the Filter in oscillator mode. The audio signal is then patched through other modules used to shape the sound such as mixers, filters, and amplifiers.

Control voltages (CV) manipulate the audio signal in several different ways.

Gates are represented by a high or low control voltage. A gate can be generated using a square or pulse wave from an oscillator or LFO, or by using a gate output from an external sequencer, or MIDI keyboard. A gate can be shaped using an envelope generator to control the attack, decay, sustain, and release of the gate. The modified gate signal can then be sent to any CV input on the synth.

A second use for control voltages is as a modulation source. For example, a control voltage from the SCI-FI S/H OUT (Sample and Hold) module patched into the 1V/O input on an OSCILLATION module controls the frequency of the oscillator based on the randomly generated sequence of notes, additionally, the OSCILLATION module’s full range oscillators make perfect control voltage modulation sources; and audio signals make excellent control voltage source for oscillator FM (frequency modulation). Understanding exactly how it works can sometimes hinder creativity—experiment!

5089 Filter Module

Description

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; its RESONANCE or Q circuit emphasizes those harmonics to the point of “squealy,” giddy self-oscillation, tracking the keyboard in its FULL setting quite nicely if seeking an alternative sine wave.

Our 5089 has the roundest, slickest tone of all the Boomstar’s filters. Go easy on it, and round, creamy buttery flavors wrap the oscillators in earthy warmth; smash it and a!meaty, satisfying overdrive, and a maximum harvest of vintage 1960s and 1970s organic-sounding, second-order harmonic distortion fill the plate. Every setting is balanced and bountiful. Looking for traditional R ’n B baselines and leads? Focus here on the rich saturation of this benchmark filter and its symmetrical cascades of generation-stretching timbres. All BOOMSTAR MODULAR filters are hand-built in the U. S. Pick-and-Place all the way!

4075 Filter Module

Description

The 4075 filter is a voltage controlled, discrete analog, 24/db/oct cascaded transconductance low-pass filter, employing handmatched 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 design is actually pulled from the four-pole ARP 4072 (better: more parts and trims), sans the 12kHz design flaw which hamstrung the original’s high end. The 4075 name has stuck—no correcting our little misnomer.

Our 4075 filter is the most requested of the Boomstar filter models, perhaps owing to its uniqueness. Has there ever been a better match for a square wave? It weaves dreams with “glidey,” 70s basslines, is a natural in the lead department, and feels as if a temper tantrum simmers a mere micron beneath its veneer of faux respectability. Aggressive and articulate, this fresh ARP can snap punishing kick drum sounds out as well as color with bright, edgy, stringy tones for essential arpeggiations.

3003 Filter Module

Description

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 in a fun, bubbly,

if washy, poorer relation, Mini “clone-ish" way; use it tastefully, or throw moderation to the wind for overwhelming chirp force.

Our 3003 filter has the most gentle sonic touch of its partners in the Boomstar fold, but nevertheless is quite capable of shaping precise, very dynamic tone. Whether or not this STUDIO ELECTRONICS filter is filling its traditional baseline boxing niche, driving a harsh, liquid, acid-like tone, a softer more rubber-bandy SH-101-ish presence, or out of the bass range altogether, leading the way, all is within easy reach of this surprisingly warm and versatile VCF. The 3003 can be distinctly vocal at times, especially when one is willing to put grittier, more distorted desires aside.

SEM Filter Module

Description

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, along with improvements by SE. It has a modest current draw, evenly from the plus and minus rails."

If you've heard the SEM filter in our Boomstar desktop (https://soundcloud.com/studio-electronics/sets/mean-sem-ranch/) you also know that this 12 dB favorite is “… capable of lighter, more subtle tones than the other three models. This isn't to suggest the filter's Low Pass mode can't cater for fat and punchy, because it can." - Paul Nagle, Sound on Sound. Deeply gratifying tonal variance and this emotional warmth https://soundcloud.com/alanc3-1/switched-on-sem—our friend Fred Falke's favorite—can reach into your head and heart, and stay as long as desired. Thank you Lord Tom Oberheim for this marvelous design/template from which we were able to work our very own Studio Electronics eurorack filter enchantments.

AMP Module

Description

From Designer Tim Caswell’s own hand: The amplifier (AMP) is a 2 stage Class A discrete design using three pairs of hand matched transistors. Envelope is usually applied to ST1 CV1; ST1 CV2 goes thru an attenuverter and can be used for envelope or modulation; ST2 CV1 goes to the 2nd stage, and is typically used for volume control; ST2 CV2 goes thru an attenuverter providing access to the final stage of modulation input.

The AMP, the 5089, and the 3003 are Class A circuits. They draw more current from the +12 rail than from the -12 volt rail. If the system power supply is under-sized, hum or buzz may be heard. In that case, larger filter capacitors and/or a larger power transformer will be needed. The 4075 draws equally from both rails, and is more immune to hum. Like our time-perfected filters, this Boomstar Modular AMP module, a gorgeous all-in-one discrete VCA charmer, is hand-built entirely in the U. S. of A—just ask Rachael Herbison!

OSCILLATION Module

Description

Tim Caswell unplugged: “Another hybrid, utilizing an exponential current source similar the the ones from ARP and Oberheim, followed by wave shaping circuits adapted from the 2nd generation MiniMoog oscillator board, and incorporating waveform mixing circuits pioneered by SE. This provides a large variety of tones that would otherwise require several patch cords and an external mixer. With a two oscillator system, that's 9 or 10 patch cords and an 8 input mixer. Modest current draw, evenly from plus and minus.”"

TC continuing: “What’s nice about our OSCILLATION stunner is that “the waveforms are DC-coupled [components connected directly together without coupling capacitors], so they keep their shape even at sub-Hz speeds. The outputs are also buffered, so the amplitude is independent of the load they are driving. The waveform levels on some modern eurorack OSCs are often all different, and they vary depending if they go into the mixer or directly to the filter!” Coupling the circuitry without capacitors in-line allows the full spectrum of sound frequencies to pass through.

GRAINY CLAMP-IT

Description

GRAINY CLAMP-IT is a granular and phase modulated 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. Be sure to wash off the sticky..."

Best to break Granny Clampett's namesake down in stages, and time travel a bit.

First Stage - Additive mixing of 4 harmonics using one of 16 waveforms, and one of 16 combinations of harmonics.

Second Stage - Granular or phase modulated mixing of the signal from the first stage, with a sync option.

Back to the First Stage - Additive section with selection of 16 different combinations of harmonics. The harmonics can be based on a sinewave or on one of 15 other waveforms. There's a separate control for mixing the selected harmonics.

Back to the Second Stage - The second processing stage allows granular processing or phase distortion. Granular processing gives you control over grain length and grain position, and can produce sync, detune, and wave sequencing effects. Phase distortion allows the signal from stage one to "look up" non-linearly, and can produce thick detune sounds and wildly varying pitch/timbre effects.!
