Re: var sig = Mix.ar(LFSaw.ar(freq*fmul))/2;

-- sounds the same, but avoids division:
var sig = LFSaw.ar(freq * fmul) * 0.5

Re: sig = Pan2.ar(sig, pan)*env;

there is already the DirtPan that should do it for you. better not to double-pan?

Ah! just saw it, thanks @telephon !

The attack, release, and cutoff parameters are also used elsewhere by SuperDirt, so you may be doubling up on the amplitude envelope and lowpass as well (although your filter gets the envelope). That doesn't hurt anything, though, and might sound better that way.
