SimApp Pro 128 button mode vs 4x32 button mode question

[kmaultsby]

I am trying to understand SimApp pro setup.  I know DCS support 128 button mode but I also fly BMS.  My question is if I understand correctly is I would have to set up SimApp Pro to 4X32 to setup my controls for BMS or any other sims, and then switch back to 128 button mode for DCS?  Is that correct.

No, you can use the unit as 4x32 in DCS as well

BUT (IIRC)

• you'll see 4 almost identically named WinWing devices in DCS keybind manage, yet they use a 'different' parts of the hardware unit, good luck finding out which is which 
• If you decide to change it from 128 to 4x32 (or vice versa) You'll have to reprogram the keybinds for all 4 'devices' separately, you cannot reuse the 128 button keybind .Lua

...I believe you can use a background program like Vjoy to configure 128 buttons to 4x32 for BMS/4x32 to 128 buttons for DCS, so you wouldn't need to switch in SimApp

Do you know if most everyone is using 4x32 or 128?

Unless you have a specific reason to use 4x32 (i.e. for BMS you had to do that a number of years ago and some other older games might also have limitations requiring that) it makes more sense to use 128.
