This is a double post only to help out the search.
These are comprehensive instructions on setting up Cantabile, the Voicemeeter Pro “Banana” virtual mixer software, and Skype or Hangouts-On-Air to be able to give piano lessons to students online and remotely, in case any of you supplement your income by giving lessons.
You could use the exact same setup to teach someone how to use any audio-producing program that uses ASIO where you need to interface with either video-conferencing software or recording/streaming software (like OBS) that only accepts WDM style inputs. Give lessons on using DAWs, Cantabile, standalone instruments and VST plugins, etc.
