  • Voltage Controlled Filter (VCF) - one fully analog 12 db/oct low pass filter with cutoff and resonance parameters
  • Envelope Generators (ADSR) – two
  • Voltage Controlled Amplifier (VCA) – one, fully analog distortion effect selection switch
  • Low frequency oscillator (LFO) - one with two waveform options (square and triangle) to control the VCF (can be controlled via CC too)

  • Audio output - one mix output (mono 6.3 mm jack)

AVP Synth had this to say about the video demo above, "In the first part of the video, MBS-100 is being controlled by Korg SQ-1 step sequencer. No EQ nor effects are applied. In the second part you can hear MBS-100 multitracked in a DAW via MIDI, no EQ has been applied only some reverb and delay at times. Drums are sequenced externally."
