STUDIO ELECTRONICS - MIDIMINI - A Timeless Synthesizer with the Soul of the Minimoog

Studio Electronics MidiMini is a monophonic analog synthesizer designed as a faithful recreation of the legendary Minimoog Model D. Unlike other clones, early versions of the MidiMini contained original circuit boards from the Minimoog Model D, giving it an authentic sound and character.

The History of MidiMini

Studio Electronics is an American company specializing in the production of analog synthesizers and musical equipment. Founded in 1981, the company is based in California, USA. In the 1980s, Studio Electronics focused on modifications and rebuilds of analog synthesizers. One of their most ambitious projects was to create a rack version of the Minimoog Model D, which led to the development of the MidiMoog. This version retained the original Minimoog circuits but introduced MIDI connectivity and a compact rack design.

Once Studio Electronics exhausted its supply of original Minimoog Model D circuit boards, the company decided to develop the MidiMini. This was a faithful clone of the MidiMoog, but with newly manufactured circuits that precisely replicated the original Model D design.

Sound Architecture

The MidiMini is a monophonic analog synthesizer that offers rich sound design possibilities.

Its main features include three oscillators capable of generating saw, pulse, and triangle waves, white/pink noise generator and oscilator synchronization, providing a wide range of sonic variations. The 24dB/oct low-pass Moog ladder filter is renowned for its warm, full-bodied sound, characteristic of the Minimoog Model D. Two ADSR envelope generators allow precise shaping of volume and filter behavior, while an LFO with multiple waveforms enables modulation of oscillators, pulse width, and filters. Additionally, the MIDI interface ensures easy integration into modern studio environments.

The sound of the MidiMini is defined by its depth and dynamics, stemming from analog circuitry inspired by the Minimoog Model D. Thanks to independent oscillator tuning, musicians can create layered, harmonically rich tones, reinforcing its strong analog identity.

Filter Dynamics at Different Resonance Settings

The filter in the MidiMini is highly sensitive to resonance adjustments, allowing precise tonal shaping.

•  Low resonance – The filter functions as a classic low-pass, gently removing higher frequencies
   for a smooth tone.
•  Medium resonance – The sound gains more punch, with emerging harmonic resonances that
   add depth and texture.
•  High resonance – The filter self-oscillates, generating strong frequency peaks ideal for
   experimental synthesis or aggressive lead sounds.

With these features, the MidiMini is extremely versatile, making it an excellent instrument for sonic experimentation.

Handcrafted Production and Calibration – Precision in Analog Craftsmanship

Studio Electronics manufactured the MidiMini by hand, ensuring precise assembly and individual calibration for maximum tuning stability, oscillator accuracy, and authentic analog character, inspired by the Minimoog Model D.

Component Assembly

Each MidiMini was hand-assembled in California, where technicians meticulously installed analog circuits, oscillators, filters, and amplifiers. Every module was tested for connection accuracy to ensure flawless operation of all electronic components.

Oscillator Calibration

Analog oscillators are sensitive to temperature fluctuations, requiring manual calibration to maintain stable tuning. Technicians performed detailed frequency analysis to ensure each oscillator was tuned correctly, preventing unwanted drift.

Filter Adjustments

The Moog ladder filter was hand-tested to verify its resonant response and modulation accuracy. Technicians adjusted resonance and frequency tracking, ensuring the filter was capable of self-oscillation for rich analog textures.

MIDI Interface Testing

Since the MidiMini includes full MIDI compatibility, technicians manually tested all MIDI inputs and outputs. They verified that the synthesizer correctly transmits and receives MIDI signals, allowing for seamless integration into studio setups.

Final Inspection and Sound Analysis

Every MidiMini underwent a final sound test, where it was connected to an oscilloscope and frequency analyzer. Technicians evaluated harmonic structures, filter response, and envelope dynamics to ensure each unit met the highest analog sound standards.

Thanks to this meticulous production process, Studio Electronics MidiMini remains one of the best-calibrated analog synthesizers, maintaining stable tuning and authentic analog character even after decades of use.

Differences Between MidiMini and Minimoog Model D

Although the MidiMini is based on the Minimoog Model D, there are significant differences. The original Minimoog Model D featured Moog’s proprietary circuitry and a built-in keyboard, while the MidiMini was designed as a rack-mounted unit with newly built circuits, following the original Model D design.

The biggest advantage of the MidiMini over the Minimoog is full MIDI compatibility, enabling modern integration with sequencers and DAWs. Additionally, the MidiMini offers expanded modulation capabilities, surpassing the original Minimoog in flexibility.

Further Development

Collaboration and Innovation

Studio Electronics contributed to several major projects, including its collaboration with Roland on the SE-02, a three-oscillator analog synthesizer inspired by classic Moog models.

The company also ventured into Eurorack modules, featuring filters, oscillators, and modulation units.

Current Production

Today, Studio Electronics manufactures a wide range of analog synthesizers, Eurorack modules, and studio equipment. Some of their most notable products include:

•  SE-1X – An advanced version of the SE-1 with improved circuitry.
•  SE-3X – A three-voice Paraphonic synth with four discrete, classic hardware filters
•  Boomstar Series – Analog synthesizers featuring different classic filter types.
•  Omega 8 – A polyphonic analog synthesizer with modular filters.
•  Tonestar 2600 – A Eurorack module inspired by the ARP 2600.
•  MidiMini V30 - Classic reincarnation of the original MidiMini with many modulation improvements.

Studio Electronics continues to uphold its philosophy of "Premium Quality Analog", emphasizing authentic analog sound and handcrafted production with an unwavering commitment to quality.

Studio Electronics MidiMini vs. Studio Electronics MidiMini V30

The original MidiMini was a rack-mounted version of a Minimoog clone with MIDI and several significant modulation improvements, while MidiMini V30 is a modern, semi-modular analog synthesizer based on the Minimoog design.

The V30 adds features like a dedicated LFO with MIDI sync and multiple waveforms, ring modulation, amplifier drive section derived from the Boomstar Modular AMP module, drone mode for always-on VCA techniques and also extensive CV/Gate connectivity, making it more versatile and capable of complex sounds than its famous predecessor.

How MidiMini Became Popular Among Musicians

Studio Electronics MidiMini emerged at a time when analog synthesizers were regaining popularity among musicians. In the 1980s, digital technology gradually replaced analog instruments, but by the end of the decade, a renewed interest in classic analog sounds began to take shape.

Studio Electronics saw an opportunity and created a rack-mounted version of the Minimoog Model D, offering authentic sound while being more compact and MIDI-compatible. This step was crucial for electronic music producers who wanted the classic Moog sound while also requiring modern studio integration.

MidiMini quickly became a favorite among musicians looking for powerful bass, cutting lead sounds, and flexible modulation. It was used by Depeche Mode, The Prodigy, New Order, and Vince Clarke, who incorporated it into their studio setups.

Why MidiMini Is Still Highly Sought After

Despite being released several decades ago, Studio Electronics MidiMini remains one of the most sought-after analog synthesizers thanks to its authentic sound, compact format, and MIDI compatibility.

Key Reasons for Its Popularity:

•  Sound identical to the Minimoog Model D due to original circuits or precise reconstruction.
•  Rack-mounted design makes integration into studio setups easier.
•  MIDI interface allows connection to modern DAWs and sequencers.
•  Flexible modulation provides creative sound experimentation.
