Hi, I'm a bit confused, since I don't know much about the topic, so that's why I'm asking to you guys.
Short story: I have an electronic pad percusion, it's a Yamaha DD-65, I'm planning to get more party from this, so adding a pair of extra pads in the future, so I've been thinking in adding a module from another Yamaha e-drum kit, the Yamaha DTX500 module to the Yamaha DD-65, I don't know if it's possible or not to connect that module to my Yamaha percusion, and how I should do it. I will add some photos of the connectors of both, so it's clear to you the possibilities.

Looking forward for your help,
