I'm not exactly sure what your asking but at risk of sounding dumb I will give it a shot. Chris Kerry has a wav encrytion module, David Haupt has modules for license generation. If this is just an analog style synth and you are trying to keep the end user from storing his own patchs you could probably manipulate that with some of the DH stuff. You might try storing your own patch list in a text file look at DH_ControlOverlay DH_Queue DH_Array to store values and forgo using the Patch Automator.
CK_Modules Pack_10 SYSTEM
Sample LOCK Tool:
'Locks' (Encrypts) .WAV files using a 'Keycode'
Locked files will not load into sample editors and the raw sample data encrypts into 'Noise'
The 'Keycode' used to Lock/Encrypt the .WAV file (6-128 characters)
Normalise(dBFS): (OFF, 0db,-6,-12,-18,-24)
The .WAV sample will be 'Peak Normalised' to the setting. 0 dBFS = +/-10v
Specify the source .WAV sample filename (*Source files are not modified)
Specifies the Destination 'Folder' where the Locked files will be saved
To Use:- Set the Keycode, Normalise and Destination Path then press 'Play'
Select your Source files individually

DH_KeyGen module is a utility that you use in SynthEdit to generate the License Keys.
There is usually more than one way to do things in Synthedit maybe someone else will offer up some ideas.
