Hi, thanks for your feedback. If you cant get the calibration right, you can always offset it in the settings.
Sheet music is something I thought about many times but still didn't figure out the way to implement it. Having just a PDF reader doesn't make sense, because it doesn't add any value to the VR aspect of it, you will have a better experience if you just print it out. Reading the PDF itself and trying to generate midi is practically impossible.
Generating sheet music from the midi files is probably possible, but it will never be even close to handmade sheets. Would it be even readable in VR and notes flying by?
This is a complex issue that I'm figuring out since the beginning. I would like to implement it at some point but I'm still not sure if VRtuos is even the right place for it. I love how you said that converting MIDI's into playable notes turns songs into beat saber maps. After all, if you can read sheet music, you probably don't need this app.
I'd love to hear more from you about this. If you want, you can contact me at contact@vrtuos.eu, or join our Discord server.
Thank you.
