The MFOS Sound Lab ULTIMATE EXPANDER in combination with an MFOS Sound Lab ULTIMATE is a completely full featured modular synthesizer. Although specifically designed to be a companion to the Sound Lab ULTIMATE the ULTIMATE EXPANDER has the features to stand on its own as a super "Swiss Army Knife" module. The MFOS Sound Lab ULTIMATE EXPANDER includes:

 

  • A State Variable Voltage Controlled Filter (doubles as a 1V/oct sine wave oscillator over several octaves)
  • A Voltage Controlled Amplifier (expo response)
  • An ADSR Envelope Generator
  • A Four Channel Active Mixer
  • A One-In Three-Out Voltage Distributor
  • A CV Inverter
  • An Analog Multiplier (Ring Modulator)
  • An External Signal Buffer
  • An Envelope Follower
  • Two Passive Voltage Attenuators
  • A Headphone Amplifier
  • Signal Routing and Buffering for The Sound Lab ULTIMATE
  • Patch Panel Design
  • Professionally machined panels and PC Boards available from MFOS

The samples below demonstrate the incredible sounds and range capable when the Sound Lab ULTIMATE is combined with the Sound Lab ULTIMATEEXPANDER. For a keyboard controller I used my Korg N1 with the FrostwaveQuad MIDI-CV Plus. I found some free MIDI files on the web with the various parts as different tracks and recorded each track separately to achieve the polyphony you hear in the sound samples below. A touch of reverb has been added to the samples.

The Sound Lab ULTIMATE in conjunction with the Sound Lab ULTIMATE EXPANDER can rival many of the vintage synths you may have drooled over as a kid. MFOS committed to having the expander available for sale by summer's end of 2009 and we delivered. The Sound Lab ULTIMATE EXPANDER is the latest tool from MFOS to help keep your Imagination, Ingenuity and Creativity solidly turned up to 11.
