The process I am experimenting with at the moment, to create a performance of a huge orchestral piece (92 VIs), is to work each instrument group at a time. So starting with the three flute parts I am loading the full presets ensuring the playback is correct then optimizing the samples before moving on to the 3 oboe lines etc.
My question is, when I have optimized the samples used in each instrument, what changes can I still make? Particularly if I change a passage from say p to f will I have to reload all the samples and then optimize again? Or are all the different dynamic levels still available after optimization?
