I have also been studying up on Zoom and other remote programs. Wrote 2 articles on how to use it. one very basic, and another with some more advanced suggestions. but not smart enough yet for the third one about other options on zoom.
I started out just wanting to find a way a group of singers could harmonize on line. turns out the delay is a killer!!! unless they can each record their own file and it would still take massive post production work!!
I did submit a recording to the latest Virtual Choir by Eric Whitacre. I am one of 17,000 singers all over the world. it debuts on youtube on sunday. quite a learning curve just to record myself. cannot imagine how they get 17,000 files synced. 6000 of them were altos, like me!!!
