[pluggo] How i can make a Plugin wich transforms audio and is Midi Controlled in DP?

sorry for this repost, but i am not native english speaker so probably my previous post was quite confused.

How would u solve the problem to make a VST Instument (unless tagged as VSTi with #C Synth; DP won't let it receive midi) wich needs an audio input from a track?
how to route audio from tracks into it? (i tried with bus send and receive but it dont work)
