and unlink isn't an option, is there some rule I'm missing.....???anyone

I use this option a lot to convert real bass into midi. 
I've never had an issue with editing the results. 
I always use a new midi track and not an instrument track. Not that it should matter. 
 
I record my bass.
I have a track template that inserts a midi track and Dim Pro ( or SI bass) track. 
I park this under the Bass track and drag the audio down to the midi track. Done. I always have to transpose up 12 to match correct pitch. 
I delete the audio track. 
There will always be some editing to clean things up. One trick I use is the drag the duration back just a hair as it always seems to overlap for some reasons.
