Nothing I've read in the Notion 6 docs suggests to me that Presonus treats 3rd party daws differently than Studio One with respect to Rewire MIDI (I could be wrong and missed something - still going through the docs and playing with Notion 6 - which is a great upgrade btw). When I rewire Notion 6 into SPlat, the option to "enable midi out" is greyed out which suggests Sonar is either not seeing an available midi connection, or just isn't looking for it with rewire instruments. Submitting a feature request in hopes this gets fixed soon.

have you guys tried Notion6 with LoopBe1 as the midi out and LoopBe1 as midi in to Splat???

Had a free day finale!   This was simpler than i thought,  should have figured this out long ago.  Did so with the help of Brian at Notion.  This is all 64 bit.
 
you need LoopBe1

Still workin on small workflow details,  but goes like this:
 
Load Sonar 
Rewire Notion 4
Notion 4   load staff from "External Midi"
In Notion4 go to Preferences> midi and set Port A  to go to LoopBe1
In Sonar load a soft synth patch and the midi input to be from LoopBe1 and the corresponding midi channel
 
The midi channels in Sonar need to have Echo On...the blue button lit up.
 
Bouncing midi to audio does not work so when you are ready to mix you must record your rewired midi track tracks into Sonar.
 
i hope Jerry will be happy...
   

I already am!  Sure, the Sonar notation editor needs some work and bug fixes, but it is perfectly usable, I've produced 13 albums, 9 symphonies, and many short pieces, songs and game cues with it.  For scoring and notation I use Sibelius, for composition and sequencing I use Sonar.  I'm not about to add another layer of rewire complexity to something that is already adequate, as my DAW has been working great for years and I want to keep it that way!
