ID Labs - Episode 3 - M-Audio Prokeys 88 Repair | Key Pivot Replacement

In this episode, which turned out to be around 30 minutes long, I dig into the guts of the Prokeys 88 and explain how the keys function, how I replaced the rubber contact strip to fix a key that would stick on sustain all the time, and then I go into how to replace a broken key pivot piece. In this case the piece I needed was out of stock and is no longer made, so I modified a piece from for a Nord piano instead.
