Convert a USB Serial device to a Midi device

Serial2MIDI

This CLI tool allows you to "convert" your serial device to virtual midi device. It also supports sending midi back to the serial device. You can use this tool with ALSA & Jack. This tool is handy with microcontrollers like arduino uno/mega which don't support USB Midi.

Features

• Supports ALSA & Jack as audio backends
• You can set name & baud rate
• Full duplex, this means you can not only receive midi but also send midi back to the serial device
• Auto reconnect, if you disconnect the serial device, the virtual midi device is still there and continues working if you plug the serial device in again

Install

Arch

There is a PKGBUILD in the AUR. Download it and install it like any other PKGBUILD or use an AUR helper like yay.
