[sdiy] Saw vs Triangle Sync

oh yeah, my bad. sorry! sigh.

btw i see a mention of the E&MM Spectrum's 3340 sync. i keep hearing 
rumours about an unusual sync mode on the 3340, ISTR used by the 
Digisound 3340 module too. is it just soft/hard, or is there more to 
it? it's supposed to sound quite special.
