I have spent the last couple of days trying to figure this out, here’s what I have figured so far.
Using Synapse 2.0 I programmed each of the 12 keys
1=Ctrl+Alt+Shift+1
2=Ctrl+Alt+Shift+2 etc.
I went through all 8 of the available keymaps, cycling through
|Shift|Ctrl|Alt|
|Shift|Right Ctrl|Alt|
|Right Shift|Ctrl|Alt|
|Right Shift|Right Ctrl|Alt|
|Shift|Ctrl|Right Alt|
|Shift|Right Ctrl|Right Alt|
|Right Shift|Ctrl|Right Alt|
|Right Shift|Right Ctrl|Right Alt|
and adding the number row of my keyboard 1 to 0 with - and = for 11 and 12
So I now have 96 useable buttons.
The next challenge was figuring out why msfs would not let me map them to the mouse settings in the control panel.
Because I have to use synapse 3 for my keyboard they are not interchangeable.
So to fix it, I used the 2nd column in the keyboard to map the desired mouse button.
Go to the keyboard mapping, select the 2nd column field that you want to set, scan input, press mouse button, Hey Presto!!!
Its a lot more complicated than it should be, and also means that I cant use any triple combo modifiers on the number row for anything else, but worth the trade, as like you, I’m using it for camera control.
Now just got to go through the same process on my Virpil and then I can finally start flying.
Hope that helps.
