It sounds to me like too low audio buffers,I get that every other time or so when starting analog lab,and running sound through the motherboards sound try upping the buffers in the audio/midi settings. I don`t think it is you,or your set up,but if you are using the computers sound hardware,I think it is an Arturia Glitch. I am looking for answers myself,as to why these things are going on.It is very touchy software, I have the Keylab 25,and will be adding a 49,and I`m a Guitar player! Love the Textures,So,,,,,,,,,
