Sweeper Noise?

[3curls]

Hello. I am new to music production and the mulab daw. I just got mulab free and it is awesome. I just have one small problem - randomly at any point of a song playing or me editing things, a sweeper noise will sound. It happens every few minutes but it never plays constanly, only randomly. I don’t know what it is and i just want to make music! if anyone knows what it is please help thanks.
