When you resize the VocAlign Project 5 or VocAlign Ultra plug-in window in Ableton Live, it may become very large and it will be impossible to resize it.
This issue only affects the Audio Units version of VocAlign Project 5 and VocAlign Ultra.
We recommend you use the VST3 version of VocAlign Project 5 and VocAlign Ultra, which does not have this problem.
You can reset the size of the VocAlign AU plug-in window by deleting the file com.synchroarts.VocALignProject5.plist or com.synchroarts.VocALignUltraAU.plist
that you will find in your Mac’s User Preferences folder.
Click on the Go menu in the Finder, hold the alt (or option) key on your Mac keyboard and watch for the Library entry to appear between Home and Computer
This is the Library folder you want, so click on it, then navigate to the Preferences folder, where you will find com.synchroarts.VocALignProject5.plist or com.synchroarts.VocALignUltraAU.plist that you need to delete.
