Studio Electronics Boomstar SEM Analog Synthesizer Module

The Studio Electronics Boomstar SEM is a powerful semi-modular analog desktop synthesizer that pays tribute to the classic synthesizers of yesteryear. The SEM model features a filter modeled after the classic Oberheim 12dB filter (complete with sweepable low-pass through high-pass bands). 

The Boomstar SEM boasts two discrete VCOs, amplifiers and filters built from hand-matched transistors, and a snappy envelope section. There are also CV and audio inputs, meaning the Boomstar can easily be interfaced with Eurorack modular gear, as well as a variety of external instruments and audio signals.

Boomstar SEM Features

  • All analog semi-modular monophonic synthesizer
  • 2 discrete voltage controlled oscillators
  • Choose between 4 classic filter types
  • 2 ultra-snappy analog ADSR envelopes
  • Voltage controlled amplifer
  • Low frequency oscillator
  • Ring Modulator
  • 2 Overdrive types
  • Glide

Oscillator 1:

  • 6 position rotary octave range switch
  • Two center-off toggle switches select combinations of sine, triangle, saw and square waveforms
  • Pulse width for square waveform
  • Sub oscillator with center off toggle switch for half and full level positions
  • Sync oscillator 2 to oscillator 1 switch
  • XMod: Oscillator 2 mod depth knob with center off toggle switch to select modulation of oscillator 1 pulse width or oscillator 1 frequency

Oscillator 2:

  • 6 position rotary range switch
  • Three position toggle switch to select triangle, saw or square waveform
  • Fine tune knob
  • Mod depth knob with center off toggle switch to select modulation by envelope 1 or 2
  • Keyboard tracking on-off switch

Mixer:

  • Oscillator 1 level knob
  • Oscillator 2 level knob
  • Ring Modulator level knob
  • Noise level knob
  • Feedback knob

Filter:

  • Frequency and resonance knobs
  • Center off toggle switch to select half and full keyboard tracking
