Thinking about this, this setup may be able to eliminate the unbreakable, but horrifically destructive chain of song parts being forced linked to variations. Separating Variation from Song parts? - #39 by pipelineaudio
This is still a massive sticking point that I don’t know how to fix. Since sadly the same midi message that picks a variation picks a song part, I don’t know how to keep peoples’ part selectors from jumping all over the pedalboard when it comes to using the event actions mode in songs. Hopefully maybe this grid can untie them (since a different message is picking the parts in this case) and somehow maybe we can get songs working.
