I have thought about what can be better for modplug, and I thought of one vst-plugin concerning the whole song.
there allready is a reverb effect, but it makes the quality of the song even worse.
Or two plugins per channel might be a solution, I don't know nothing about c++, so maybe it is impossible, it would be splendid if it is possible.
I also use reason to make sample, because that program can use more effects on one channel
