Switching between songs causes intruments to get stuck

[MartinSStewart]

I started playing the default song, then clicked on a_better_love. When I did that both, some instruments from both songs played and got stuck in a loop. I'm using Firefox on Mac. (This is specifically for the demo here, https://elm-tracker.netlify.com/ I have not tried building the library)

Hello Martin,

I'll try to fix the most annoying bugs like you described. I already experienced the same behaviour. Thank you
