Description
I added many slides inside my tab, maybe those slides went wrong while start playing from the midst of tab.

To Reproduce

Open the .pt2 file and navigate to the 18th bar and press spacebar to play, the violin (vocal) will be out of tune (sometimes lead guitar will also be weirdly shifted)

Additional Info
I cannot find its bug pattern as listening to the bug is a torture to my ears. The report also looks less elegant, sorry for that.

This is what it should sound like (exported perfectly and buglessly from Power Tab Editor (alpha18-51-gf11404c3)).
