KVR Audio

Okay, so im a new user to MuLab and had a lot of fun with it in the past few weeks.
But today I finished a new beat, and exported it, then i listened to it again, and heard that there are strange, wind-like sounds every 30 seconds or so.
Then I opened MuLab again to see if u had put a sound in by accident, but I couldn’t find it.
But now I get this sound very often, and not at specific times in my project, and it’s very disturbing.
I hope someone can help me with this, because it’s ruining my best project so far

That noise means you have reached one or more of the limits in the Mulab demo, if you want it unrestricted I'm afraid you are going to have to buy the full version but its not too expensive.
