Yes, I can finally put that question to rest. For those of you who have no idea what I'm talking about: I'm refering to the overdriven Guitar Sample used in my Rev2 DLS update for FF8. Previously, I thought it was simply a public domain sample, as I found it floating around on the internet, with no apparent documentation telling me who owned the copyright for it. As such, I have always said that I don't own the sample, nor do I take credit for its creation (well, other than conversion to DLS format...but that is a minor thing).
Until now. I can finally give credit for where it came from. Of all things, it's actually a squaresoft sample! Lucky me.
I was going thru the PSF archieve for Chrono Cross, and apparently, the same exact sample is being used in "Etude1.psf" and "Etude2.psf", as well as the "226A-Magical Dreamers.psf" and "226B-Magical Dreamers.psf" files in Chrono Cross (aka Magical Dreamers -- "The Wind, Stars, and waves"). You can tell by the feedback characteristics (just like in the Rev2 DLS, only certain keys produce a slow feedback as the note is sustained), and the overall tone of the sample. Though, it appears the existing sample I have is missing some stuff in comparison to the Chrono Cross version....ironically, it sounds like it has correct samples for the higher octaves (that "wah" sound in Magical Dreamers B, to be specific).
Needless to say, this caught me by surprise....its still awesome though.
A quick way to compare to yourself (assuming you have the PSF archieve ready for comparison purposes):
Magical Dreamers test MIDI from Vgmusic.com-edit-
erm...I accidentally clicked submit too soon.
Anyway, using Winamp 2.7x or higher (but not Winamp3), load the Rev2-patched DLS up and play the linked MIDI file, and compare the guitar to the one used in the PSF. Practically identical harmonics-wise, eh?
2nd Edit
I needed to get a little more specific on the file names.
