Midi tracks to audio tracks

Hello. I have several VSTi loaded via instrument tracks, and each VST consists of 8 channels, so I have 7 other “Midi Tracks” per 1 instrument track. Other 7 are set to differnet channel in order to correspond to the patches I loaded in each channel in VST. (It is set up this way so I can load less instruments and save up CPU).

I need a way to export each channel as Wave to send it to a mixer, but under the audio mixdown, no midi tracks are shown.
What’d be a solution for this…?

You might be better off loading each sound into its own instrument track.
It uses a little more CPU time but the load is spread across the cores More evenly.
