Yea that is interesting. I did not know about the M$ DAW development. And fishing for DAW developer talent just got easy!
Gibson wanted more market so there was MAC development of Sonar and then not a lot of info and it got shut down.
Sonar code would save MS a lot of work and give Gibson some cash to give their creditors.
If it had sonar features and flow and would work with Windows 10 updates I'd try it out.
