Details

This is an advanced project requiring understanding of electronics and electronic building and trouble shooting skills and equipment. Access to a good oscilloscope, DVM, bench power supply, soldering station and hand tools will be required. Only the schematic, circuit description, and suggested panel layout are provided. Please read over the entire project before ordering PC boards or other products.

 

Features

  • Expand one CV input to eight CV outputs.
  • Expand two CV inputs to two sets of four CV outputs.
  • Three CV outputs have adjustable portamento.
  • Expand one gate input to six gate outputs.
  • Three gate outputs have adjustable delay (1mS min and 1.8 Sec max).
  • CV and Gate output levels are easily settable.
  • Gate input comparator accepts wide range of input gate level.
  • Zeners limit both pos and neg CV excursions.

Introduction

Once you start building up your modular you quickly learn that you need a lot of CV outputs to drive all of those VCOs, VCAs and VCFs. Additionally you never seem to have enough gates to drive all of the envelope generators, sequencers, and other modules that require them. That's where the MFOS CV and Gate Expander comes in. One CV input can drive 8 buffered CV outputs or two CV inputs can each drive four buffered CV outputs. Three of the CV outputs have portamento (glide). The gate input can drive 6 buffered gate outputs. Three of the gate outputs are op-amp drive and three of them are CMOS drive. The CV output is zener limited to provide protection from over-voltage. The gate output voltage levels are all customizable.
