One of my big optimizations is to see what kinds of things (controls
or even audio) that can be re-used by many synths. If it can, become
familiar with busses and routing. If you are using 10 reverbs with the
same settings, see if you can create one reverb and send your 10
synths to it (for instance).
Best,
Josh
