I am almost 100%positive that the contact pads were installed and the top keyboard shell is pushing them off center thus missing the contact switch pad underneath.

I would open up that keyboard and touch those contact pads to see if you get a signal touch.

Almost all the new keyboard controllers are using soft rubber contacts that also act as a spring thus they are so cheap that they don't even have a spring on those momentary buttons anymore ( Hello window buttons on newer GM vehicles LOL).

Imagine the Linndrum when it came out if it had the behringer buttons that look like they won't last a week of heavy usage!!!
This is going to happen to the Behringer drum machine since they are using soft contact rubber pads that are not hard centered on a solid mount like the old LinnDrum machine with the heavy duty button pads that are still working after 30+ years.

With the move away from higher quality lead soldering, away from harder ABS plastics all these instruments are now just toys compared to the 1980's electronics and plastics.

 

Waste of time and money if you paid for something brand new that isn't working. If it's past warranty, then sure, fixing is the way to go. I have a whole workshop for servicing anything with components and I would still not open it if I can send it back for a new one.

 

if making sure the Midi Control Center is up-to-date, doing a Factory Reset, and flashing the firmware; it's something physically wrong inside the controller.

 

yes you are right, I should disregard everything I've seen and learned to be "sensitive"...

ha..............

 

No, you can do something, I'm proud of you, an independent doer. You are also able to help other people with their problems. In the neighborhood they say, ask Garamondo Furbish, he'll fix it. Please note that my sentences are serious and not humorous.
