The aim of this project was to build a fully functional synthesizer based only on electronics and software that was used in the 1980s.
The Z80 CPU was chosen, being popular in may an ’80s classic, having a good following still even today, and actually being a very nice chip to work with.
The oscillators are based on the Juno 106 DCO (Digitally Controlled) with analog voices using 3320 filters.
The Z80 synth is almost complete, a few more software tweaks to do and the analog voice boards to finish, then we can get a sound!
