While some keyboards provide media keys or even knobs to adjust your overall computer sound up and down, often what you really want is the ability to tune program volumes separately. To make this extremely easy, SNR Tech Bytes has come up with a beautifully-designed controller, which runs on the MKR ZERO.

The device features five encoders to individually tune the master volume, Discord, Chrome, gaming, and Spotify, with the help of software on the PC itself. Encoder button mutes each channel as needed, using NeoPixels below to indicate each status.

The build is based on the deej volume mixer, and more specifics on this version are available on GitHub.
