The issue can manifest in two ways:

• If you stop playback in the middle of a sustained note or chord on some audio instrument tracks, the remaining unplayed portion of the note or chord will sound the next time the song is played.
• With affected DSP plug-ins, the issue is slightly different. If playback is stopped before reverb or delay tails of any of the plug-ins decay fully, the remaining tails will sound just before the first region in the track is encountered on the next playback.

If a bounce is performed in situations where the next playback would exhibit this issue, the resulting bounced file will also exhibit the unwanted audio snippets.
