Hi,

There are some bandlimited signal generation techniques.
The most famous are
- BLIT (BandLimited Impulse Train - 
https://ccrma.stanford.edu/~stilti/papers/blit.pdf). The idea is that 
you generate a bandlimited impulse train at a give frequency and then 
you create the classic waveforms by means of integration
- BLEP (BandLimited stEP - 
http://www.cs.cmu.edu/~eli/papers/icmc01-hardsync.pdf). The concept is 
the same but it use bandlimited step function. It also provide a means 
for hard synch between generators/oscillators (actually I think it was 
conceived fot that reason).

Cheers
