Just as a follow up for Logic Users.
In my Logic preset I use a number of momentary buttons to mimic keyboard short cuts in Logic.
So I have an edit page which has a set of buttons for each of the tools that can be assigned to the mouse or trackpad when editing a section of music
The issue I was getting is that Logic particularly when opening an existing project would “light up” some of these pads on electra. The effect of this is that I had to press the pad on electra to turn it off before I could press the pad again to activate the learned functionality
I couldn’t really understand why logic was sending feedback to the electra when all the feedback options in Logic were turned off
What I have found is that to actually turn the feedback off in Logic you have to set the drop down Feedback list to none but crucially you have to leave the tick in the Text Feedback box. If you remove the tick from the Text Feedback box (which is what I was doing) then logic will continue to send feedback
Another tip for anyone integrating electra in to a Logic setup and piggy backing mackie control messages. The control surface manual for Logic is essential reading. However, try and find the PDF for version 7 of Logic as that seems to have more details including a full midi spec and details of how logic constructs sysex messages for updating of the scribble strips on a mackie controller.
