Hi John,
You have a maximum of 3GB Expansion Memory available for all Expansion Voices that you want to install at the same time. Of course you could have
several Pack Install files on a USB stick. But you then have to
reinstall the correct pack whenever you want to use the respective voices. USB sticks can NOT be used as additional expansion wave memory.
A basic "
Full Pack Install" file is in the .c
pi format (or .p
pi if only unprotected packs are involved).
A "
Quick Pack Install" file is in the .c
qi format (or .p
qi if only unprotected packs are involved).
Casper (ckobu) had shown in one of his tutorial videos how to create a "Basic" Pack Install file (.cpi) and, if desired, several "Quick" Pack Install files. Please note, however, that these Quick Pack Install files can only be installed in the order in which they were originally created. See the mentioned video from time position 7:00.

P.S.
Unfortunately, "normal" users do not have access to special compression methods that Yamaha uses for the voice samples in expansion packs. Voices created by the user, on the other hand, can only be realized with uncompressed WAV samples, so these Voices need more space in the expansion memory.
If you use Sample Robot and specify "best" or "good" or "original" quality, the automatically generated / looped / key mapped samples / sf2 files will probably be relatively large.
However, you could achieve a lower storage requirement by ...
- using fewer individual samples, i.e. do not sample each key individually, but use each sample for e.g. three consecutive keys and / or
- using shorter note lengths, loop lengths or, for samples that have not yet been looped at all,
use a loop (and implement the sound decay via a corresponding amp envelope).
Quote from the chapter "Ultra Quick Start" in the
Sample Robot 6 Pro manual (page 11):
"Please note that the higher the values for Velocity
Layer and the lower the Key-Step the more detailed
the virtual copy gets, but on the other hand it takes
longer to record the instrument and more disk space
and more software sampler performance is required.
So it is wise to choose a compromise between quality
and quantity."Best regards,
Chris
