I am seeing a different validation error, using the V3 Filter Demo sample source. I'm building it under Mojave with XCode 10.3, and made a couple minor changes to get it to build (use of Swift 4.0 and stubbed out a couple small blocks in AUv3FilterDemo.swift, namely a call to presetState and the override of supportsUserPresets, which are not defined in this rev of AUAudioUnit). It works fine in the demo app, but fails to validate in auval (and thus won't load in Logic).I get errors of this form:--------------------------------------------------FORMAT TESTS:Reported Channel Capabilities (explicit): [1, 1] [2, 2]Input/Output Channel Handling:1-1 1-2 1-4 1-5 1-6 1-7 1-8 2-2 2-4 2-5 2-6 2-7 2-8 4-4 4-5 5-5 6-6 7-7 8-8X X ERROR: -10868 IN CALL Cannot Set Output Num Channels:2 when unit says it canERROR: -10868 IN CALL Cannot Set Output Num Channels:2 when unit says it can* * FAILIt doesn't seem to matter what I set for the Channel Capabilities (the default of [-1, -1] yields several more of these). Any idea how to fix this? I haven't found anything online about the cause of this error. Is there some reason this won't work in an XCode 10.3 build?
