Touchscreen Controlled Circuit Bending Patchbay on Roland TR-626

The solid-state patch batch bay I built got moved to it's new home (a Roland TR-626) this last weekend. In this video I go over the GUI and the memory settings a bit... (Note - If you don't care how this was done and just want to hear the finished result, then check out the video here- http://youtu.be/nu6FfKYgT78 )

Basically, there are 47 bend points I've connected to in the TR-626. They are connected to a 48x8 crosspoint switch circuit array I built. Any of the swittches can be activated/deactivated and are controlled by an Arduino Mega. This give me 8 independent buses or 'patches' at any given time. Each of those patches can utilize any/all of the 47 inputs. (Within reason, connecting + to - for example is disallowed.)


(Sorry there's no demo/audio. I'm working on that... In the meantime you CAN hear this same patch bay on a different drum machine (a TR-505)  from my 'proof-of-concept' build here- http://youtu.be/JZRpz0zVbfM . )
