Hello
I have a question - are you aware of any existing (or planned) score object for PD, like "note~" or "Bach" for MAX/MSP?

The only one I'm aware of is Ed Kelly's Gemnotes project. I don't know if it's still being developed, but it looked promising.

I'm not positive if this is the most recent version or not:

Thank you! I found info about Gemnotes, but didn't find the download. Gonna check this soon!
