yup... thats the website. :/ and what is this "ugh" ! ... its a free open source editor!! The dude "Atom" is dedicated to making it happen so you don't have to spend $200 on synthquest that probably doesn't even support the Hawk-800 in the first place.
if you don't like it you can continue to program the korg the old fashion way. its the best programmer ever. talk about ugh. ;)
Cheers!
