OK - HURRAY!!!! I found the way to rename and delete the performances I didn't want. That makes this a keeper! It's got a few possible functions for my work:
1. Great studio scratch pad for laying down a fast arrangement for a singer or client to hear.
2. Super small command center for my midi guitar, in case I'm not using the keyboard.
3. Nice add-on file player/drummer for jobs that have a house piano. (I get them once in a while)
4. "MIGHT" be an all in one tool if a stand-a-lone harmony unit is connected to the audio ins .... haven't tried this yet, but I'm thinkin' of it!

*** One point I must make ***
In order for the BK7m to give me a manual split bass and drum machine, I had to mute all the style parts and keep the arranger turned "ON" for some reason. I think the arranger triggers the split point and assigns the zones. EZ workaround.

Here's the setup:

Nord midi OUT to BK midi IN
BK midi OUT to Nord midi IN
Nord Local turned "off"
BK midi thru turned "on"
**ALL program change info in the BK had to be turned off so the Nord didn't send weird sounds to the selected real-time parts. Most controllers wont have this issue, because you can program it to send what you want. I want the Roland to do all the work so the Nord is still ready to function as a standalone midi instrument in other scenarios.


Still ONE little thing to figure out:
When switching from one performance to another in real time, I can't seem to filter out the command to change the rhythm style. Sometimes I like to play manual bass for a while, and then solo with the auto stuff .... it SHOULD do this. I just haven't found the command yet. I found the section that filters it almost everything else, but this is a puzzler.
Hmmmmmm
