Sticking A button on wireless controller

Can the Xbox Adaptive controller be paired with a controller, so that all buttons function as normal but the left thumb stick function gets replaced (reassigned) to the left track pad but all other controller buttons, triggers, and right thumb
stick function as normal on the wireless controller?

The simple answer is yes, you will be able to set it up doing what you desire in conjunction with the copilot system.

To sum the information up in one post:

Yes, it's worth the update, as you can bind different button combinations to the lower paddles. So you don't have to take off your thumb from the right stick to jump or reload or whatever you need the face buttons to do, so you are more agile and look around
while you do "button-stuff".

You can store up to 3 button set ups for different games and switch to these profiles with the push of a button.

It also comes with several exchangeable sticks in various lengths and grip to give you more "control" (pun intended) over the travel of your stick or how you place your finger on the sticks. And you get to change the "stiffness" of the analogue sticks. So
you might set one stick very soft for quick travel, and a more stiff resistance for finer control.

And lastly, you can set up the way the trigger travels. So if you play a lot of shooters, you can set the controller to a hair trigger mode, where you only have to pull the trigger a few millimeters, or if you like driving games set the trigger movement to
full to get that extra throttle or brake control.

While there is no wireless dongle in the box, it will work with the existing wireless dongle you already have. Also, the controller supports Bluetooth (however, not everything works via Bluetooth compared to the wireless dongle).

As another poster already mentioned, the wireless dongle supports up to 8 controllers, 4 controllers with chat headset or 2 controllers with stereo headsets that will play game sound (even in spatial 3D). With Bluetooth you're limited to game chat sound.

Try this procedure: right stick, select one of the sensitivity presets.

Scroll to Xbox Elite Wireless Series 2 Controller and select Configure. Select a profile to adjust or create a new one. Select the Edit button and on the Left Stick or D-pad tab

The Elite V1 does not support bluetooth. It can only connect to a computer using an Xbox Wireless USB Adapter stick, and that's what the sync button on the controller is for. You can however still use the controller via USB cable.

Razer sucks. I went through three before I gave up on them.

First one the A button stopped working, second and third had a large amount of drift in the stick.

If you want wireless then you need to stick to the official Xbox controller.
