I had a posting SNAFU. Here i some text that was supposed to accompany my attachment.
I’d love to see if anyone can coax a GR300 out of Hotsawz. I tried. I failed. IMHO Hotsawz is very flexible but designed to do other things.
Ironically, Synthonizer factory preset TROMBONE FACTOR comes close (was someone at Eventide was gunning for this sound too?).
I have attached my best work (which took an hour or so and ended up very close to TROMBONE FACTOR … oye). It works best in a limited range (D,G,B strings in the middle of fretboard) and is only one sound (Metheny seems to use at least three variants). It does have reverb, which is a small plus over Hotsawz. But it might sound closer to a GR300 if you turn the reverb off and run it into a Lexicon since that is a big part of Metheny’s sound too.
