Hello holmes9139 and welcome to the forum.
What OS are you using?
Make sure you select the correct drivers for your interface in AT4 and, if it's Windows, you are using an ASIO one, preferably the manufacturer's own drivers.
Also, your processor speed will have a bearing on glitching, but most modern CPUs should be able to handle fairly low latency settings.
Hope that helps.
