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
http://www.nerds.de/en/loopbe1.html 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...
