I'm fairly certain there's no real way to do this in FamiTracker, any fork (and Furnace doesn't even loop DPCM samples correctly lol) without retriggering the sample over and over (which sounds kinda ugly) or just putting all the pulse widths in one giant sample. And even if you did that, that would heavily limit your PWM speed possibilities, unless you use even more samples.

There very well could be a driver out there that can do this already, but regardless, I wrote my own program to play this sound. It truly doesn't do anything fancy except bump the sample address in one direction or the other after every NMI, and allow me to change the pitch of the sample by pressing UP or DOWN. There aren't any non-game-viable tricks going on here, and the total sample usage is still only 408 bytes. :P

Speaking of changing the pitch, you also can't smoothly change the pitch of a sample in FamiTracker without retriggering it, which again sounds kinda ugly if you're doing it quickly (perhaps for the purpose of a wavetable kick). I wrote a different program before this one that I forgot to save to see if it worked at all, and sure enough, that worked too.
