Easier said than done. Does this just come with time?

Do you want the actual harmonic series, or just any scale that contains the harmonics as a subset? Try just intonation, it's all about ratios.

Good point! I’ll try that.

4ms smr is the single most amazing accurate tuning source for harmonic, microtonal ad other scales - theres hundreds of scales built in and it'll drive u to 6 vcos polyphonically

Also, keep in mind that the theory behind FM synthesis and the theory behind tuning systems are two different things, even though the way they both use ratios can make them look similar. It’s possible to make connections between them, but when you’re first learning it helps to keep them distinct.

There are a lot of non-harmonic ratios that can sound great with FM. Really it comes down to using your ears. Octaves or other integer ratios are just the guaranteed easy ones.

I like it when the ratio produces strong undertones which become the new perceived fundamental. Just-slightly-off ratios are also great for creating movement within the timbre, somewhat similar to chorusing.
