So I received a couple of USB to Serial adapters today as I was curious as to how well the serial MIDI interfaces on my various sound modules would work in a VM, as well as using them on an older yet still serial-less laptop.

For the heck of it I thought I'd play around with the Hairless MIDI to Serial bridge, designed to allow Arduino devices to communicate via MIDI to a PC or Mac.

This worked for all devices I tried with it - Roland, YAMAHA, and KORG sound modules. There's even a fork specifically for multiport mode with Roland modules - https://github.com/tyan0/hairless-midiserial

Anyway, I thought this was an interesting discovery that might be of some use to someone.
