I know that there is a built-in VST in FL Studio called MIDI-Out. Recently I experimented with some dubstep basses and I wonder if it is possible to use this VST to control the sequences inside one plugin.

In Piano Roll I can color the notes for 16 different colors that refer to 16 different MIDI channels. So far I have three different basses (screenshot on the right) I would like to connect to the MIDI out and already did that using the same port. However so far as I play a note in Piano Roll all of the basses are playing at the same time. My plan is to assign for example the first bass to the blue notes, the second one to red notes and the last one to a green note. Do you happen to know how to do that?
