I make webinars based around teaching music production using software like Pro Tools and Garageband and I'd love to be able to use my computer audio and stream it to viewers as they view a screenshare of me working within the software. As far as I've seen, no other webinar platform allows this. As a result, the only workaround is to pre-record any of my in-software tutorials and play them back in the webinar but this doesn't allow me to answer questions and help people on the spot. I understand that the microphone input is important but by being able to use computer audio as an additional audio input, it would be huge for people who want to play any music.
