I play guitar and I do computer music on Ableton Live. This software has a looper, but it is not so efficient and I needed something better to play... Therefore I started building a USB foot controller with cheap stuffs!
Check the following video to see what it looks like
Three things you need to know before to start:
-There might be a few mistakes, I do not usually speak english
-This controller works on Ableton Live, I do not know about the others softwares, depending how to configure the controllers...
-Before to built the controller, I checked on the internet if some had the same idea and I found relevant posts. I thought to built it with an old keyboard, and many people already did it. Here is my favorite:https://www.instructables.com/id/Hack-a-USB-Computer-Keyboard-to-Make-a-Synth-Pedal/
So I based my work on this instructable, adding few steps and comments.
Now that you are ready,
