Awesome tips thanks guys..
Sadly I can't use the RME with the laptop yet, since its firewire. I can chain 2 apple dongles to USB-c; I just need to accept that buying $100 in dongles from a $2 trillion company is my best option
I downloaded ASIO4ALL and Oxygen61 is now showing up in my MIDI list! Audio is working but MIDI keyboard is still not playing the VST, but there's progress at least. Its also showing in device manager, so USB3 I assume is not the problem.
