“This tutorial makes up part of the portfolio submission for a creative research project based around DIY instrument builders and online DIY communities that I undertook in the final year of my BA. The aim with this build was to provide a bridge between a number of open source software and hardware platforms. I designed it with musicians and artists in mind who may have some experience in DIY electronics and who wish to consolidate this knowledge by building an instrument with real functionality that can be easily expanded upon. This tutorial will show you how to build a simple synthesizer from start to finish using an Arduino nano, the MOZZI audio library for Arduino and a few common electrical components. I have provided two different programs that you can upload to the Arduino to get two different sound engines. I would love it if people started to experiment with the code and build their own synthesizer engines for the hardware.”
