Not sure if you're talking about the new-age album Jerry did where he used DX7s and MIDI guitar. That's another thing.

Thor's paper on FM suggests that Formants help a lot with modeling the electric guitar. This is an FS1R feature not carried over to FM-X at least from a operator standpoint. I've had difference with the absolute require to produce certain instruments without formants -- but I would say that the "usable" range of the instrument sounding representative for other instruments is decreased without formants. Which just leads to expense in resources since you have to split up your keyboard range into multiple usable segments using more operators than you would otherwise need.

Jerry's tone is cleaner - but this thread

https://www.kvraudio.com/forum/viewtopic.php?t=206772

Shows use of the "DX7"'s (FM keytar) in the last post running through distortion. He's got external distortion and guitar-like cabinets - but with the wealth of effects on Montage - you can probably get in the ballpark of this more distorted keyboard using on-board effects. Which is a reminder that effects complement FM-X unlike what could be done in the distant past.

Thanks! Helpful stuff.

What's "Thor's paper on FM?" Do you have a link to it?

I didn't include a link to Thor's paper because it doesn't expound on how to create an electric guitar sound - only that formants help.

The paper was "presented" to the group in this message: https://www.yamahasynth.com/forum/deleted-110/latest?viewallreplies=1

... back to that last post in the KVR thread about Jan Hammer:

Notice he didn't go looking for an FM patch on his synth that matched his goal of "distorted electric guitar". The synth he used had a couple presets - or a couple of things that were were good enough. His requirement was "something with a sharp attack and reasonably long sustain.". That's it. Any FM preset that matched that - he would use amps, effects, and most of all - playing technique to bridge the gap.

The guy played with some of the heavier guitar hitters around and traded licks with them - so he had a good chance to get his chops together.

But also read (you can find more about him) that his approach is starting with anything and getting a good "guitary" sound out the end for that work that needs that sound.

That thread and that PDF are really relevant and helpful. I'm going to try Thor's method of letting a spectral analysis of the sound I want guide how I attempt to build it with FM-X.

Thanks so much!
