I haven't seen anyone else talk about this, so I figured I'd put this out there: I finally got to try a Roland MT-32 via wireless MIDI, and it works perfectly. My wife gave me a Yamaha MD-BT01 for my birthday, and it's working flawlessly. Gets all the power it needs from the MT-32's MIDI ports, and it's able to play to it seamlessly via macOS's builtin support with zero lag. If you, like me, are tired of wired cables and just want to be able to play without hooking anything up I can recommend it
