[phasor~] is not the right object to use as a sawtooth oscillator?? In the latter case, what should you use instead??
Because it has DC offset...the signal is only in the positive domain. If you don't care about aliasing, you can do this:

(ohhh, I see maybe: it is because of aliasing isn't it? indeed I always wondered: how do you simulate a sawtooth oscillator and avoid aliasing [without a huge oversampling and filtering]?)
Generate bandlimited waveforms. Works for lower frequencies, however higher frequencies will still alias...
