It's not a session using a .ses file as such. But yes, in AA1.5 I open the 3 songs, bed file and 2 link files, do a bouncedown, it takes 12 secs. I close all files and exit. Open AA1.5 and repeat the above with the same files and it takes 12 secs again. I have 2GB RAM if it helps to know it.
AA2 I hasten to add, is still running after exit in all other use, so I have to manually end process every time.
In AA2, in Preferences | System I had set Wave cache at 500MB, using the logic that the more RAM I assign to AA2 the better, probably not fully understanding what this setting is about. After changing it to 50MB (I forget what the default is), the test boucedown now takes around 55 secs instead of 2 mins 35 secs. And now AA2 is not running after exit. Hmmm... I think I win 'idiot of the week' prize maybe
But I would like to know what Wave Cache is all about. In Photoshop fopr instance you can assign 50% RAM to it and it all runs much better, I guess it's not the same logic in play here with AA2.
