This inexpensive wireless gamepad works great in vArranger2. It allows me to assign any 10 functions to control vArranger2. I am going to add a mini Bluetooth keyboard. The whole setup will give me scores of functions to control vArrnager2- all wireless while strolling around with my accordion. I was at least 40 feet away from my MS Surface Pro and it still worked fine.

Nice found

You will be able to START/STOP, change variation, sounds etc... wireless and also play video game during the pause

No time for game because I play vArranger during the work hours as a Korg Microkey 61 sits always right in front of my monitor and during the break, I also play vArranger during the break!!! Kidding aside, it is just nice to be able to control just about all functions of vArranger from inexpensive Korg NanoKontrol2, wireless PC keyboard, and a bluetooth gamepad/joystick! So much control. I have a midi controller called Control Freak!
