Hey, maybe you should read the thread instead of bumping it and basically reiterating a bunch of stuff. If you did you'd realize that virt already posted here about his plans for VGMix and that djpretzel also posted that we're exploring some similar functionality for a Workshop overhaul.
In any case, as much as I like VGMix (I released quite a number of songs on VGMix 2), these forums are not VGMix development forums. If you're serious about doing something about getting that site back up and running, VGMix still has their forums online. Have fun and good luck.
