It looks like this script solved the problem: > [@Getting multiple buses working for AU and VST3](https://forum.juce.com/t/getting-multiple-buses-working-for-au-and-vst3/60078/4): > > Hello, I’m scouring the forum for multibus issues and found yours. I’m similarly trying to get all sorts of combination of layouts woking acceptably in Logic, Cubase and Pro Tools. One thing I can’t see if you’ve mentioned with your Logic issue is whether you do a full reset for the rescan. I’ve found having to do this between changing supported layouts. The brute force script seems to be this (found elsewhere): #!/bin/sh sudo killall -9 AudioComponentRegistrar rm ~/Library/Caches/AudioUnitCach… During troubleshooting, I was regularly deleting **com.apple.logic10.plist** and **com.apple.audiounits.cache** , but not **com.apple.audio.InfoHelper.plist** (which I suspect is the culprit) and **com.apple.logic.pro.cs** (which I believe is related to control surfaces). The script also terminates the **AudioComponentRegistrar** process. Note that using this script resets Logic preferences. Since running the script for the first time, I’ve been able to use any plugin version and code combination without having issues in Logic anymore.
