LinPlug Spectral - Manual (Page 85)

Additional Sounds
Below the credits there is the area to enter more licenses for additional
sounds. Whenever you purchase new sounds from LinPlug you get a serial
number to be entered here. When your DAW software supports copy/paste
you can easily enter the serial this way, otherwise you have to enter it
manually. Once entered correctly the Serial Number turns into the name of
the sounds you just licensed.

- Per Preset options: setting which are stored within each preset. Per
presets options control how Spectral works when loading this particular
preset. They are too saved with your song or project in your DAW.
- Per Instance options: These are valid for each instance of Spectral, that is
for every instrument you open, and only for this one. They are not
affected when you load another preset. They are used to make one
particular instance of Spectral work in a desired way, of course this is
saved with your song or project in your DAW.
