This is a question most of your would expect other people would be asking me instead of the other way around, but here goes:
Does anyone know of a web app virtual piano that allows MIDI input and also has more than 6-note polyphony? I have looked at 30+ options, and there are plenty that accept MIDI, but the polyphony is abysmal for all of them.
^ I need to do a remote sing-along session with students next Friday, via Google Meet. Meet only lets you share system audio through a Chrome tab.
My backup plan is to just park my laptop on top of my real piano, but I won't have the balance control I would have with a vocal mic and my MIDI keyboard.
