Are there other methods or techniques?

Phase modulation with feedback can produce exquisite sawtooth, some alternatives here:

Noob: How to do classic (DX7 style) operator feedback?

Hi, I am currently trying to learn how to do FM (DX7 style) in SC. The DX7 allowed phase modulation feedback not only inside a single operator (as in algorithm 3 and 5), but also over several operators (as in algorithm 4 and 6): [DX7_algos3456] I learned that SinOscFB has a built-in phase modulation feedback, which gives the acoustic result I am looking for, but only for one oscillator. I would like to learn how a phase modulation feedback loop over several operators can be achieved. As first…

Here, the first two harmonics (or operators) feedback in the phase parameter:

(
SynthDef(\PM, {
	arg  freq=110;
	var sig, index=1.5;
	sig = SinOsc.ar(freq: freq, phase: index*LocalIn.ar(numChannels: 1, default: 1)) + (SinOsc.ar(freq: freq * 2, phase: index*LocalIn.ar(numChannels: 1, default: 1)).softclip);
	LocalOut.ar(sig);
	Out.ar(0, sig*0.1);
}).play
)

Going wild in the modulation can lead to some interesting aliasing effects:

(
SynthDef(\PM, {
	arg  freq=110;
	var sig, index=SinOsc.ar(1/10,3pi/2).range(1.0,1.8);
	sig = SinOsc.ar(freq: freq, phase: index*LocalIn.ar(numChannels: 1, default: 1)) + (SinOsc.ar(freq: freq * 0.001, phase: index*LocalIn.ar(numChannels: 1, default: 1)).softclip);
	LocalOut.ar(sig);
	Out.ar(0, sig*0.1);
}).play;
)
