You know, I could have sworn I found a few libraries that had key switches from SoundIron that the Art Conductor didn't have mappings for. But now that I'm looking for them, I cannot find them. I have only recently purchased the Omega bundle from them, so I haven't had a lot of time to delve into all their libraries yet. I will have to keep an eye out and I'll let you know if I find any.
I did find some inconsistencies with the ones that are currently mapped. For example, in Olympus Elements > True Legato folder, each instrument only has two syllables: Ah and Oh. Those are each mapped twice - so on Olympus Elements Legato Ensemble, there are two key switches for men and women.
The Art Conductor mappings have a bunch of syllables that are not in the instrument, and they also don't trigger any of the women's voices. This seems to be the same for all the instruments in the folder.
But if you go to the Marcatos folder, it has all the correct syllables but only for one side. This seems like the case for most of the Olympus instruments where there are keyswitches for divisi or for two different vowel articulations.
Another example of this is Elysium Harp. In Elysium Harp Amb - Chromadrone, there are keyswitches for Layer 1, but not Layer 2.
