Hi Mike,
When one starts Vienna Instruments for the first time of a session, the application requires time to examine the licenses. This action takes a minute or so then followed by loading the instrument samples. The more libraries you have configured in the Directory Manager, the longer the initial exam takes.
One approach to minimize that is to load only the instruments in the Directory Manager that you are using for a particular template. I have all the libraries of VI but never use everything available, so I pick and choose those instruments that I will be using in a given template and save them as a preset in the Directory Manager. Also note that this process only takes place during the initial load when the machine is first started or after a reboot.
When I was having problems with eLicense, a blank white box would appear on the screen. Sometimes the box wouldn't be blank but would have an Syncrosoft error message on it requiring a reboot. I have NOT seen this since I've loaded Snow Leopard, and the latest release of eLicense and VE-PRO. I feel pretty confident that the issues has been fixed through some software modification between the three apps stated. No hardware changes have taken place on my end.
One other work-flow approach that I find beneficial is to use the metafile function in VE-PRO. Because I have only a single machine and Logic allows only 16 channels per instance, I use multiple instances of VE-PRO (ie. winds, strings, perc, keys, etc.). Once my template is complete, I save a metafile that keeps track of the VE-PRO configs along with their screen positions. Very nice when using multiple monitors.
In the beginning of my day, I click on a metafile (which I've created an alias and place on my desktop) and the loading process begins. The licenses are checked, the VE-PRO instances are loaded along with their samples. This takes approx. 10 minutes for the entire orchestra and choir. While this is taking place, I have my first cup of coffee and read my emails, check for updates on the web, etc. Once everything is loaded, I bring up Logic, load my sequence (which takes about 30 seconds) and I'm up and running.
Want to use the same template in a different sequence with the same template, just load a new sequence leaving VE-PRO up. Switching to a new sequence is about a 30 second task. The instruments are already loaded and ready to go.
I've been playing around with different approaches to optimize my workflow. This approach works the best for me.
Hope this helps.
