It would be nice if you could alter A=440hz to make some organ renditions more accurate (i.e. the sanctuaries in deltarune), or change the tuning system to reflect historical organ tunings. This tuning block would go between the windchest controller and the row of windchests, and is linked to the tuning controller, possibly through its own channel system or redstone links.
It could also open up an opportunity to create microtonal organs. 👀

Could be nice to not have it as a separate block, but rather a GUI associated with windchest controller
I suppose that would give it less control though. Which is probably fine because the proposed architecture, if placed adjacent to controllers, would supply redstone to both instead of just one or the other
Having it a part of the windchest controller, and having a windchest controller manager block would make the most sense to me
