Don’t panic, the reason is probably due to a bad setting of your software.
In Standalone, go to “AUDIO SETUP”, you will find a line: “AUDIO BUFFER SIZE”, you will have to refine the setting. The higher the value (e.g.: 1024), the more important the latency will be, the lower the value (e.g.: 64), the shorter your latency will be. This setting depends on the power of your computer, it is up to you to find the right setting.
