I haven’t looked into this yet because I have no way to test it - but there is a big push right now for “ATMOS” support. AFAIK, plugins cannot interface directly with the ATMOS Renderer but I am wondering if we can support 7.1.2 for the “BEDS” channels generated in the DAW.
UPDATE: It does support 10in/10out but it seems it does not fully support all other combinations up to 10 channels.
The reason is that “#define AAX_TYPE_IDS” seems to only handle up to 9 configurations. If increased to 10 it creates a compiler error “too many characters in constant”.
So it seems iPlug currently cannot support everything from 1 channel (mono) thru 10 channels (7.1.2) in the AAX format. It works in VST2 and VST3 (haven’t yet tried AU). Some combination (like 7 channels, 5.2 or 7.0) would have to be unsupported.
Unless someone knows a workaround or fix for the AAX “#define AAX_TYPE_IDS” 9 configuration limit?
