AUD.ini is a simple text file stored with the rest of the user files in C:\Users\yourUserDirectory\appdata\roaming\cakewalk\yourVersionOfSONAR. Multiple versions can be stored and replaced at will. Whether what you want to do in entirely is the AUD.ini I cannot say. If the AUD.ini is not found when SONAR starts, a new one is created. How are SONAR and SAP comparable?

 Thank you very much, Member scook. You've encouraged me to attempt this.
 To answer your question, as far as I can tell, Sonar and SAP are comparable in that they are both complicated, highly user-configurable Windows programmes. I will confess to not actually knowing whether or not SAP even has an .INI(are you supposed to use "an" rather than "a" when the next character is a "."?). So please forgive my pretentiousness.

SAP is not simply a Windows program. It is a very large multi-platform business solution. The Windows parts of the application came years after the mainframe version. It is true SAP can run on Windows now but SONAR and SAP have little in common, this may be part of your confusion.

Thank you very much again, Member scook. You are helping me refine what I was actually trying to address when I typed my OP. 
 When Cakewalk first launched it wasn't Windows either(I wasn't paying any attention at the time so do correct me if I'm wrong) I guess I could say that the Windows parts of Sonar came after the mainframe version, as well. But I can find the options for the screen layouts, or whatever, in SAP, even ones I'm unfamiliar with, quicker, just by guessing, easier in SAP than with Sonar. I came to SAP way after I came to Sonar, and I care way more about Sonar than I do SAP. This to me does not seem like it can be some kind of familiarity bias. This is of course, completely subjective.

 On the other hand, my aspiration to "Power-User" of Sonar is a lot stronger than my aspiration to "Super-User" on the RR SAP network. Maybe I dig deeper into Sonar. Maybe if I took my day job a little more seriously, I would be, right now, on the SAP user forum, asking why everything can't make sense just like Cakewalk Sonar X3e.

True story: Microsoft held a focus group to nail down new feature requests for Word. They narrowed down the list to the top 10 most frequent requests. All of the features were already in the program

SONAR has always been a Windows application. The versions of SAP I have worked with ran on multiple servers and thousands of desk top machines. I don't think it is helpful equating a product like SONAR designed to run on a single Windows machine to a multi-user client-server business application. Is there a single user version of SAP which runs on a single PC? Anyway it would seem a distraction, if one is looking for solutions to SONAR issues.
 
I was hesitant to reply to this thread until Sanderxpander gave a specific use case. If my reply to Sanderxpander provided a solution to your issue even better.

 That's actually amusing. But on whose face does this put egg on? The users who are asking for features they already had, or the Word guys for allowing this to happen?  

One of the delightful aspects of SAP for me was navigating the help system and having it suddenly switch to German. Something SONAR has yet to do. Even more fun was watching Seibel and SAP consultants spend millions of other peoples money and produce nothing. Good times.

god sap's a mess
