Hey Super,
Thanks for your response.
However, I was not looking at GM versus GS, although I agree with you, there are many "GM" soundtracks that are really GS or at least SC-55 optimised GM.
I was talking about music composed for the SC-55, where there are SysEx strings attached that are only functional (if I understand correctly) on higher level Sound Canvas modules (88 and up).
In this case it was not a music programmer, but someone who recorded the MIDI, edited it very nicely, and optimised each track for the Sound Canvas even more than the original composer- some tracks have Hall 1 reverb, and some have higher level reverb than others. But the Delay macro change has me stumped- it seems to be used on the QuestStudios' KQ6 Soundtrack CD:

(See tracks such as Nightingale, Cave, Catacombs, which all have the delay enabled, and compare to a SC-55 playing the same tracks, ignoring the MT-32 instruments used in some of the CD tracks.)
However that delay section is not present on the SC-55 and its' variants. This makes me think the MIDI was edited on, say, a SC-88, in a SC-55 map (but using SC-88 SysEx) or maybe it was a SC-55 and the SysEx was simply a mistake, wrong manual or some such.
Anyway, enough information from me.
