I think you're almoste there ... "Erase Track" on that last window will remove the track content. So, Click the track description->Track Actions->Erase Track
If you want to remove the RealTrack musician, click the track description->Select RealTracks->Choose No RealTracks for this track.
thanks. I understand. Choose no realtrack, just keep midi
If you choose to erase, there is nothing left.
And my understanding is to delete, clean, so I didn't find it.
thanks
However, after I tested it and erased it, it was regenerated again, so this is a different concept from BIAB VST's clear.
