Looking on [OSStatus — Apple API Errors](https://www.osstatus.com/search/results?platform=all&framework=all&search=-66745) the error code is `kAudioUnitErr_RenderTimeout`, maybe processing is taking too long in that specific case, maybe your processing has some non-realtime safe code? Notably it’s happening for 1 channel that might be something to consider when reviewing your code. ---

Thanks for sharing, Do you know what file that would be? ---

It’s most likely an issue with your `processBlock()` function in your `AudioProcessor`. I can’t tell you what file that is in as it’s up to you what file you define that function in, but by default it would normally be something like `PluginProcessor.cpp`. ---
