Annoying Crackly Noise

Having trouble with LMMS? Ask about it here.
OK, just posted it to soundcloud. (haven't adjusted volume yet, so you might need to turn
The artifacts only happen in the first couple of seconds.
I'll PM you the link to the project in a minute.
Thanks for your help!
I've been messing about with zasfx for a bit, and I finally managed to find the envelope control.
I adjusted the attack time to ~15, and now everything is fine. Woo! :D

It sounds a bit different since I took the attack time so far, but I think I like it better this way anyway.

I still don't understand why this would only happen on export, or why it only happened at the beginning of the song, but what matters is that it sounds a lot better.

Thanks all for your help!
I cant explain the export thing either, but great that you have it fixed, but there is one more rather important thing you need to do. You should assign separate FX-channels to each instrument in your project. You only use Master, and not only does it limit you mixing opportunities, you can also have artefacts.
Here some video on mixing:
