Introduction
The MFOS Ten Step Analog Sequencer is a great first sequencer project. 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. This sequencer design is simpler than the MFOS 16 step sequencer and has fewer steps and features. Nevertheless, it is still a challenging synth-diy project and unless you have experience building projects from scratch I can't recommend it unless you have a helpful and experienced electronics buddy. A sequencer is a mainstay of any modular analog synthesier. While not necessary, MFOS offers a very cool voltage quantizer that can be connected to the output of this sequencer to ease set-up of chromatic sequences."
