Thx John
Its’ a newly installed SD3 V 3.1.2. with the SSD drive updated from SD2. Specs; PT 12.5.2. iMac 2011 i5, 16 GB RAM. I’ve found that using some more recent third party software instruments together can cause problems for PT. For instance Vienna Instruments with several other instruments. Arturia V series is a big problem making it most unusable, even by itself. Sd2 was never a problem in itself but I assumed SD3 was just pushing CPU over the limit and that I might need 8 GB in each of the 4 available slots to cope if I am running 3 powerful software instruments simultaneously. Either that or PT has buggy issues which is quite believable. I have tweaked buffer sizes but it doesn’t make a noticeable difference.
