DIY MFOS 16-Step Analogue Sequencer KB

We always recommend visiting the MFOS website before building where the latest 'offical' information and news can be found. Here on the Soundtronics website, you will find selected information from the MFOS site plus additional information and resources to aid the building and maintaining of your MFOS synth. This is not going to happen over-night but during the course of 2014, it will start to take shape as we document our experiences in the construction of these modules. We would also like to include any experiences, hints and tips from customers as well so feel free to contact us or simply post a comment using the form at the foot of this page.

Introduction to the MFOS 16-Step Analogue Sequencer

The main idea of a sequencer is to provide an automatic means of sequentially stepping through a series of adjustable voltages to drive a VCO (or any other voltage controlled device). Additionally, gate and trigger signals are generated at the moment the output of the circuit steps to a new voltage. Typically you use a sequencer to control the frequency of an oscillator (or several oscillators) to produce repeating tonal patterns, or arpeggios, which are further enhanced by filtering, modulation, addition of keyboard voltage etc.

Features

  • Sequences of 4 to 16 steps in length
  • Modes include stop at count, reverse at count,
    reset at count and random 16 mode
  • Each step has coarse tune, fine tune, and switchable gate
  • Accepts external clock and external start pulse.
  • Simultaneous outputs with and without portamento.
  • Forward, Back, and Reset controls ease sequence set up.
