I’ve been performing my music in Second Life for the last 18 years (yes, SL is still around.) I’m upping my visual game with a small utility app I made that takes an incoming MIDI note and transmits a song title and BPM into the game. I’m using it to trigger visual effects in SL. I’m hoping there’s more to be done with syncing things to the BPM, but I’m happy with the result for now.
