Problems mixing down the song

problems mixing down the song

ARGH! I’ve been mixing down my songs and they sound find on N-track. But once they’re converted to .wav files, this sick noise keeps popping up throughout the song. It sounds like an annoying keyboard track or something but I havent put in any MIDI and it’s not on any of my audio tracks. This sound just pops up on the mixdowned songs and it’s really annoying! Has anyone had this trouble before or have any suggestions? Please help!

Got any demo plug-ins in the song? The demo version of n-Track does this for some folks, but I think it does it during playback and because it’s demo mixdown is a bit disabled in some way. This is odd that it’s only in the mixdown. Is there any way you can post a short clip so we can hear the sound?
