Unable to export audio parts #16
Description
Hi, thank you for this project, I'm able to have synchronized score playback directly in the browser and it works great.
However, it seems like I can't export audio from separated parts with setExcerptId. I tried on the PWA app as well as by modifying the provided example without success.
Is this expected and just needs to be implemented (I could try to have a look into it) or seems like a bug ?
