Hi Alex and welcome to Antescofo Forum!
You should be able to get what you want but not straight out of the box. You should first get hold of the Music Score of what you want to track/follow in real-time. If you have a MusicXML version of your score, then just drag-n-drop it into AscoGraph which is a standalone software that comes with both Max and PureData Antescofo packages. This will Convert the music score into the Antescofo Text Format and will allow you to embed actions inside it that will become the basis of your Isadora control.
And the good news for you is that OSC is already embedded in Antescofo. This means that you don’t need to learn Max! Just learn the Antescofo action syntax and you’ll be able to set it up so that it’d send through OSC to an external port (check the online manual on OSC).
Some users in this Forum have been successfully controlling / triggering SuperCollider, Jitter and CSound in this Forum. Let us know how it goes!
