Must I go back to 8.5 and Win 7 to record my midi's audio?

My post about this before died for lack of followup. I have tried the new method of getting the audio from recorded midi tracks using external instruments as an intermediary. I had problems with the last segment not being recorded and also found that though my PK2 has 6 audio outs into the Presonus SL16R mixer, there can only be one PK2 external instrument, so each time I want to record one of the other tracks, I have to the first one done, change it to no instrument to free up the PK2 and then reassign it, and so on with each track using it.

It seems that my previous method, with Cubase 8.5 in win7, was simpler. There I had to just route the audio output of a midi device to new track set with that as input. this was using Firestudio Project as mixer. So I have thus been unable to succeed in routing likewise after seeking help from Cubase forum and techs and Presonus., so finishing all the songs recorded with midi only are stuck there where they can’t be finished for mixdown. Is returning to the C8.5 and win7 going to be the best way. I thought of looking into Studio One of Presonus, and found they don’t even have midi tracks, bypassing apparently to external tracks which I would probably have the same issues but there I can’t even get a song started for a rate incompaitibly issue. Just hours day after day trying to solve problems without creating or finishing musical projects.

Routing your midi tracks out to your synths and recording as many of them at a time as your interface connections allow by selecting that interface input as new audio track inputs will work just the same as it did in 8.5.

What bit of routing is not working…does midi play your pk2 (what even is a pk2, google doesn’t seem to know so not sure how I’m supposed to :))
How is midi getting to it? USB?..5 pin?..via another device?
What pk2 outs are connected to what interface ins?

I couldn’t figure the routing. I was seeing these inputs labelled for drums, like BD, SD, MT… etc. apparently left over from when I had the 3 Firestudio Projects and one was for drums.

I started to experiment and saw a signal when I had input to BD, when the bass part played on a song and it was in the mixer as PK2 M1. If I went to change or rename, I got a warning that it was used in song. I ignored and changed and then was able to record the part. I changed all the names and assignment inputs accordingly, and now I think I may be able to record multiple tracks of the PK2 to their own audio tracks simultaneously, instead of using external instruments as intermediaries and having to unuse or name the PK2 each time I wanted a new track.

Unbelievable breakthrough for me, though simple, but I couldn’t find the necessary help from the forum, Cubase tech nor Presonus tech to understand what to do, for weeks and after having the mixer for almost a year. The main difference seems that software replacing actual knobs of the FSPs resulted in a lack of understanding.
