Thanks to Oleg Malinin my gui piano works without any sound delay. He's really nice and eager to help me. I almost gave up on making my piano work right, but then he communicated with me and helped me fix the code. Even though English isn't his first language, he tries his best to communicate in a clear manner, thus there's no language barrier at all. Thanks Oleg!
