@jtstephPerfect. Mark had explained to me why additional buffering may help, so its great to hear that its working for you.I will do some testing in Isadora 3 with the same setup. I expect with some of the  improvements that have been made that performance will be even better.

Added a bit to my original post about using the Data Array actor with textfiles, containing my controller and note values, to map my midi controller to parameters. It is a super useful actor that made quick work of mapping the controllers, and allowed for flexibility in making changes.
