“My SampleTank software seems to be loosing memory of where the various instruments are when I reopen a song in Digital Performer. What am I doing wrong?”
Currently SampleTank doesn’t look across multiple root folders when opening a session. So if you open files from different root folders to be used in one song your best bet is to create a separate folder for the sounds you are using in that session so SampleTank only has to look in that one place to properly open it. There will likely be a better resolution for this in upcoming versions.
