my vision shows me: do it like the instrument FX...
IMVHO and in a perfect world, the entire track DSP chains system would be replaced with how it works in instruments. You would map tracks to effect chains just like you can currently map instrument samples to separate effect chains. Just like with instrument effect chains, Send Devices can send the signal to any effect chain that comes after it. Nothing is special about "Send tracks" any more, they're just a receiving effect chain, of which you can have as many as you like. As a programmer (and I did write a soft synth once, 1100 bytes, it was), it did always bug me, we don't like special cases, and "Send tracks" are like any other kind of routing, but they're made "special". I have since learned that this is a relic from routing in studio hardware.
Anyway, it doesn't matter much I'm 169% sure that the Renoise routing, processing and mixing pipeline is a hell of a complex beast and it would be nigh impossible to turn it around like that (and this is entirely understandable and nothing wrong with). More importantly, it would completely and utterly break backwards compatibility with earlier Renoise projects, the whole structure of a song would be different.
