Hello, I recently purchased a Yamaha Motif ES8 and some keys are acting weird, especially the middle F. The key is mostly fine but if I hit it at an angle from the right then it seems to get stuck against the E to the left of it, it gets back up just fine. Could it just need a cleaning or lubrication?
In case I need to replace keys, could I use my yamaha p-45 as a donor?
Thanks in advance.
