My DIY Arduino Synth Sounds Rough… Here’s How I’m Fixing It

In this update, I’m showing the current state of my DIY Eurorack-style synth modules built around the Arduino Nano. I start by demonstrating the sounds these modules are producing right now, then break down the sound quality issues I’m running into — and how I plan to fix them. This project is all about experimentation: pushing cheap microcontrollers into places they probably don’t belong, figuring out where the limitations are, and redesigning until the sound actually hits the way it should. I’ll be digging into filtering, output stages, power noise, and overall signal quality as the build continues. If you’re into DIY synths, Arduino audio projects, Eurorack-style modules, or experimental electronic instruments, this series documents the entire process — successes, failures, and everything in between. ► Watch the full DIY Arduino Modular Synth series: https://www.youtube.com/playlist?list=PLXlhPLEraM1Ce37QVYKCeCZZVWB0gqG6I #arduino #eurorack #diysynth #electronics #modularsynth #sounddesign
