Hallo,
is it even possible define the note names like i want in the piano roll editor?
 
Greetings Tomas

If you mean having the note names on the notes in the piano roll it must be possible, I believe Studio One and Cubase have this feature.  Sonar seems to be falling behind some of the other DAWs when it comes to MIDI.

OK. I thought that i named the keys from the piano roll to the name of the strumming keys from aas session .

You could create a drum map for that I suppose?

I agree. I totally forgot drum maps. I'll look later. Thank you.
 
Greetings from Tomas

Drum maps may be a solution, but the ability to right-click on a key and name it whatever you want would be pretty nice.
 
Regards,
Dan

It is possible to add Note Names definitions for the PRV. They are stored in the .Note Names and .Instrument Definition sections in the Master.ins file.

Which is located in "Cakewalk Content \ SONAR Platinum \ Instruments".
 

The Master.ins read by SONAR is in your user directory.

Interesting.  I did a search of my C drive for it before posting and didn't find it, but did find in on my Content drive.
But it is in fact also in my user directory. Even searching C:\Users and C:\Users\Paul turns up nothing, I have to go down to the AppData level.  Got to look into that.
 
The one in Cakewalk Content has been modified more recently than the user folder one, fwtw  (2011 vs 2010).
