Hi Paul in reference to what you quoted:
"The strangest part of all this is that when I setup a new instance with the same patch and instrument, plus I tried with a Piano patch from Goliath (which was fine)"
I had meant that I made a new template and added an instance to find the problem was gone, with a fresh setup. However now I have rebuilt my Strings Instance with Violins, VIolins II, Violas, Cellos and Basses in, I find the issue back.
I am not sure how it could be PLAY since I have had no issues until this week.
I updated PLAY to v6.0.2 about a month ago and it was working fine
Short of formatting both my systems, I have no idea what the solution could be
Hope someone can shed light on this
Thanks
