Hi Samuel, as an alternative to [phasor~] you could try either [creb/blosc~ saw] or the one Roman Haefeli just suggested:
>If you're after a cheap band-limited saw generator, check this out: >https://github.com/reduzent/pd-bloscabs >It's pure vanilla and cpu-wise not much more expensive than [tabosc4~].
