The fun stuff with rendering oscillator sync is figuring out which oscillator or oscillators reset during a particular sample period, and which reset came first if both oscillators have reset since the last sample. Only then can you correctly apply BLEPs to remove the aliasing.

And for triangle waveforms you have band-limited ramps (BLAM) to deal with as well, in order to remove the aliasing generated by abrupt changes to the gradient of the waveform!
