Sound drop out on VSTs why?

Any ideas from the community why the sound cuts out when using VSTs?

There is data in the track but it can not be heard. If I replicate the VST and move the data - it works for a bit but another may cut out or the same one.

Try opening the Audio Performance Meter while playing and see if it maxes out when your audio drops out.

Thanks SF will do.

I am working on another tune today but hope to get back to the one that was dropping out tomorrow.

If it is maxing out, what do think I should do?
