Notator supports MIDI system-exclusive (Sysex) messages meaning that you can dump patch data for any MIDI device as it's instrument independant. It's very easy to use as well: just set the sequencer into record, then dump whatever MIDI data you may want from your MIDI synthesizer, effects module etc.
You can save yourself a lot of time and hassle by keeping everything in one place instead of having to search for that particular patch in your MIDI librarian.
Here you can keep all that data together with the song itself!
