HI all.  I am a blind user of the MX 49 and have some questions.  First, how do I select sonar as my Daw for use?  My next question is a bit more detailed.  I am able to edit performances using the John Mella’s editors.  I can get the Arpageos set the way I want them.  I am not editing the individual voices, just settings in the mix.  When I either hit F6 to store or hit Store on the front pannel, if something happens, I can’t tell.  I know it doesn’t store the performance, I have to go back in to my pc and get it from the mix file.  Can someone help me on this?

First, how do I select sonar as my Daw for use?

you press the dedicated [DAW REMOTE] button to enter Remote Control mode.
Then press [UTILITY]
Press the UP CURSOR arrow to. Ensure you are the top of the list: DAW
Turn the DATA WHEEL clockwise four clicks to SONAR

Thanks very much for your help.  As you can imagine, using the motif series keyboards are all about memorizing menu structures.  Learning how many presses it takes to go where and do said task.
