Synth Build: VCO #2

This is actually one of the few modules in this build that are not designed by Ray Wilson. They were designed by Thomas Henry. The schematics are indeed his intellectual property as are technically Ray Wilson’s. However, this synth will not be a commercial product so I should be fine. I needed another VCO to

Synth Build: Envelope Generator and VCA

First of all, ADSR is Attack, Decay, Sustain and Release; VCA is Voltage-Controlled Amplifier. These two circuits work in tandem with each other and the rest of the modules to produce correct amplitude modulation of the signal. That is to say, it controls the intensity of a note/sound and if it is on or off.

Synth Build: VCF

This time I decided to make a combination module to save space on the panel. This VCF (Voltage-Controlled Filter) design is supposed to take up a whole panel. However, I knew that the harmonizer was a relatively simple circuit and it would not take up that much room. The size of the heap of parts

Synth Build: LFO

This LFO (Low-Frequency Oscillator) is a voltage-controlled type. This makes it very similar to a VCO except that it operates at a much lower frequency. A VCO might operate at frequencies spanning from ~0.1 Hz to ~20 kHz. This LFO operates from well below 1Hz to about 600Hz. In fact, at its lowest frequency setting,

Synth Build: A VCO Module

This prototype will consist of a complete (or near enough) build of a single module for the synth. The purpose is mainly to to test construction techniques that will be used on the rest of the modules. Wire wrap construction is used for about 85% of this build. The idea is that everything would be
