Personally, I would store the parameters in an .ini file. In the File VIs are the Configuration File VIs and they are really good for reading sections and keys. You could have one large .ini file with a section for each instrument or you could create an .ini file for each instrument. Either way, you can save your parameters in the keys and get them back later.
I lean towards having fewer .ini files and keeping things a little
cleaner in the file structure.
