Instrument VST MIDI -> Instrument; audio output to master?

I was fooling around with routing the MIDI output of a Maschine 2 VST instrument to the Sampler “Electric Red” instrument.

The Maschine VST has it’s own pattern sequencer, so it’s outputting MIDI notes by itself when “played”, without any input from Renoise.

I got it working, but notice the Sampler instrument is playing the MIDI(from Maschine VST) notes’ audio out directly to master.

Is this by design? I’m guessing so, cause how else would you assign this output to a specific track?

Renoise plays back plugins on the master when they got not triggered anywhere on a track.

Add a note or CC at the beginning of the song in some track, it will then play it on this track.
