The link worked for me. And thanks for posting this - I'm very excited
about this mod. I was about to do it last week, but when I fired up my
PolySix for the first time in months, I found that it no longer wants to
produce sound . . . ah, vintage.
But seriously, as soon as I have time to trouble shoot this issue I'll be
performing this mod.
Cheers,
James
