Sadly, not really. Most tutorials just brush the surface or go in hard with no further explanation. It also depends on if you really want to create your own FM-sounds or if you want to just use them.
However I thing a generally good introduction into what FM even is and on which logic it works is a video by Andrew Huang. However this would only show the synths side.
For working with FM you need to keep in mind that this sound creates complex waves (additive synthesis) but doesn’t have any further filtering. With analogue you’d always have a complex wave filtered down. So first things first will be always to either EQ or filter those FM-Sounds and tame them a bit. Also Since they have such a metallic sound, they also beg to get some special information like a reverb. But on those points only some experimentation will work. Look out for what you like and don’t. See how you like your synth sounds in general. Do you like additional modulations like chorus? Does it need to drip with reverb? Do you like spaciousness created by some stereo delay? Do you like your synth sounds played into an amp? There are no real limits on what you can do after you recorded a synth sound 😊
