expoting issue

[1v1 beats]

I've been using LMMS for quite a while now, and since yesterday I've been having this problem with the exporting.
when I export my audio and open it up in audacity, its just a loud distorted bleeping sounds that range from 6 to 14 seconds long and I don't know what it could be. If anyone knows how to fix this please respond ASAP!

Thank youu <3

I'm having the same issue.

I encounter this problem when:

I use the Vinyl effect
Tempo is very fast
Certain VST's or plug-in that LMMS cannot handle (example, using an sfxr preset ans it is playing many notes, as sfxr is only used as a sound effect, not a general plug-in for playing melodies)
Using a LADSPA effect that has "Multiband" in its name
A plugin aside from AudioFile Processor playing beats in beat/bassline editor

This probably means that an effect unit you're using is buggy, giving you bad data.
The fastest possible fix for this is to try the latest beta release of lmms-1.2 .
If this doesn't work, mute the channels one by one until you find the offending track.
In the FX tab, before any reverb/delay, add a Waveshaper Effect and check the Clip input box.
