Congrats on the new beta - glad that stability/software efficiency are priorities for the release!
Scala - see it's off the list. When you first mentioned it on an old roadmap I didn't know what it was, but since then did a lot of research around it.
I see there are ways around not having it universally implemented in AM e.g. using CSE, but now that you've implemented musical note names for most contraps, I'm hoping that some time in the future it will be incorporated.
