Hello all,,
I also found it long to load large long 2 hr projects.(No plug ins used except Sonar defaults)..But that is with system setup issues.
Since finding and sorting out the system problems as I find them...Yep it takes time to load up large project files.. I found if I close the project and Sonar, and reopen without rebooting the system...Sonar loads it faster the next time around., almost instantly.., and if I boot up, and reopen that file, it takes time all over again..(win indexing?)..Again I am finding more and more system issues, and solving them...As I go backwards and forwards,... So take this with a grain of salt and lightly pepper to taste.
I see Sonar is Drawing in the wav files slowly when this happens...and notated this also in another thread.
