I've had some buggy/inconsistent behaviors when using Logic Pro 10.7.7. A song file crashed and I removed and re-installed each plug-in. Afterwards, I got several tiny inconsistencies, such as losing the ability to control the volume of various NI instruments from either the Logic workspace or by the Kontakt slider. A tech rep from NI mentioned that Logic 10.7.9 is a 'safer' version than the previous. Can you please corroborate that for me before I update my Logic 10.7.7 to 10.7.9.
