If you want to explore various combinations of phase modulation, linear through zero frequency modulation, ring modulation, amplitude modulation, and hard sync, then I recommend Venom XM-OP. It makes it easy to experiment with all of the above, and you can control the amount of oversampling used by each oscillator to control aliasing. Unmodulated sine doesn’t need any oversampling. But modulated sines typically benefit from oversampling in the range of x2 to x8. XM-OP provides convenient controls to specify musical ratios with integral numerators and denominators. You can also explore the effect of different waveforms - you are not restricted to sines.
Here is a quick example I patched up using four sine XM-OPs with Valhalla Supermassive for some extra ambience at the end of chain.
I use the new polyphonic Venom Random for four different slow smooth random voltages to control various aspects. The root pitch for the patch is C4.
XM-OP 1 uses a ratio of n:3, where n varies, centered around 7. The output level also varies.
XM-OP 2 uses a fixed ratio of 8:3 and varying output level
XM-OP 3 uses a fixed ratio of 3:2 and is ring modulated by a mix of XM-OP 1 and 2. The output is a constant mix of the unmodulated signal plus the ring modulated signal
XM-OP 4 uses a fixed ratio of 1:1 and is frequency modulated by XM-OP3 at a constant level, and also uses varying levels of feedback phase modulation.
Finally the output of all four oscillators is mixed and fed into Valhalla Supermassive running the SFX->Nebulae->Planetarium preset with mix at 70%.

The new Random has been submitted to the Library, but hasn’t been released yet. You can get the new Venom release below:
