You can find the answers to many questions here, it’s very likely someone before experienced the same problem as you do. Otherwise you can also submit an issue ticket and wait for our help.
If you've installed version 1.0.0 or 1.01 you're probably still using a demo of LuSH-101, and you need to be aware that one of its limitations is sound getting out of tune (floating sound pitch) after 30 minutes.
If you have purchased a full version and still sound gets out of tune, you should look at the LuSH-101's About box and check out if your copy was properly activated (your registration name taken from activation key file should be displayed there).
