A gracious thanks to all who helped!  The undocked Browser synth power button is THE answer!  Works nearly instantly with immediate results in the RAM meter.  And my project loaded in 2 minutes instead of 9!  There are several sampling synths I didn't disconnect - they have much smaller RAM footprints.  Or should I disconnect them until I'm ready to use them, and further decrease load time?????  So many options now!  Thanks again - I appreciate it immensely!

Fortunately there is a way to disconnect a synth without undocking the browser and clicking the power button. When docked, the selected synth may be disconnected by toggling the "Synth Connected" option in the menu in they Synth tab.

Even easier!  Thanks Scook!  By the way, I just also disconnected my Kontakt instruments, leaving only a couple of others active, and my load time is down to 4 seconds!  Guess I'll be moaning once it's time to enter those parts and re-activate the instruments!

FYI, disconnecting synths, bypassing FX racks (an option available in the FX context menu) and turning off ProChannels is how the freeze function frees up resources.
