Not all FM synths are alike. The FM4, which, according the teh internet, is an FM synth modelled after the Yamaha TX81Z. The building blocks, the variations of sines and inverted sines, sound pleasant and are useful in bringing out unique FM timbres. The waveforms are a bit rare in commercial FM synths today.
The different "models" reproduce lush and pleasant digital audio aliasing to various degerees, inspired by legacy technology.

Highly recommended.
