I am running Midi Guitar 2 on Windows 10 and am wondering if there is a way for me to use my guitar with this website: https://sightreading.training/(or similar). The only midi input option that the site gives me is my audio interface. Is there a way to make this work?
that is a not really recommended usage of MG.
if you want to try, just put a midi cable between the out and input on your interface, and adress the output in MG.
You can also use a virtual midi loopback cable like loopMIDI
