fantastic feedback and thanks to avid support & pro tools expert. i was going to purchase a S3 and will postpone this. i've uninstalled EuCon now completely (/Applications/Euphonix).

this issue was driving me nuts during the project completed last weekend. i'm on a trashcan and couldn't imagine, that it is running out of ressources.

disabling sierra's eye candy improved the performance dramatically as well (system preferences > accessibility > display, uncheck reduce motion, reduce transparency; system preferences > dock, disable effects and so on...).

macOS ... what the hell, apple. come on!
