but isn't it some kind of perversion to use a host under the host under the host?
Naaaaaaaaah, it's totally cool.
Renoise example got so much better VST system than OMPT, but i'm still using Chainer in it 'cause it makes my life so much easier with ember volume, panning, wet/dry, multiple input, drag and drop, easy turn on/off, and... well, that chain VST system =).
Don't look at Chainer as a "workaround", look at it as an OMPT extension that makes it "perfect". =)
