I am learning to use Sonar Home Studio and hava a project with a track connected on Midi 1 to my D70. The default patch list is GM which does not map to my D70 properly. I can choose 0-128 but would rather have the correct names showing. It looks like an instrument def. file would do the trick. I tried to make one by starting with a Roland E-78.ins file and then importing it but that isn't working for me.. so far. Any help guys? thx. John

Did you look in the Roland.ins that comes with Sonar. I see a lot of SC-D70 patch banks. Is that the same as the D70? You should be able to model your INS file with it. 

Here's instructions on how to write an ID:

Good luck!

Thanks for the reply Dave. In my Sonar Home Studio 7 install folders I don't see any Roland.ins file. I have searched my full C: drive so I probably don't have one. Would you mind emailing me a copy of yours. Send to verobel@sympatico.ca
thx. John

belay that last reply.. I did find Roland.ins but it just came up with a weird icon next to (bad association file type). I was able to open it in notepad and cut out what I need and saved to D70.ins on my desktop.. will try to add other ctrl lines as per Gregs linke below. Thx. john
