Eurorack is the leading standard for building modular music hardware, arguably cause for some of the wierdest sounds in the electronic music industry. Despite the existence of development platforms for Eurorack focused on using commodity microcontrollers and the availability of (closed source) FPGA-based synthesizer modules, there is currently no easy way to get started in creating your own FPGA-based music synthesizer hardware. In this talk Sebastian will present his 'eurorack-pmod' project, a collection of open-source hardware, gateware and software that makes it easy to get started in the world of FPGA-based audio synthesis using only open-source tools (such as Yosys + KiCAD). This talk begins with an overview of music synthesis in the context of Eurorack and illustrates how the 'eurorack-pmod' hardware and gateware makes it easy for you to get started making your own high performance music hardware.
