One of my ASR-10 keyboards I have had for over 20 years. Even when I first bought it in the late 90’s, the keys were already beginning to yellow. Over time, and playing my keyboard near the window, UV sunlight has yellowed the keys. I already have my keyboard apart, so now is an ideal time to address it.
I am wondering if the Syntaur Key Renew product on sale on the front page of Syntaur would do the trick. I assume it is not meant for this application.
Research online brings me across products such as “RetroBright” or DIY fixes such as using Hydrogen Peroxide products in high concentration products (such as for hair) in combination with sunlight or UV lights to reverse the process.
Here are some questions:
Does removing the keys and then reattaching them later require any kind of re-calibration? I read somewhere online that removing the keys and they reattaching them requires a computer re-calibration that only EPS professionals had the equipment to perform. However, people normally replace their keys and I doubt they do any sort of sophisticated recalibration.
If I were to submerge the keys in a solution, I should probably remove the metal strips on the bottom of the keys. Any advice or caution about doing this?
Can someone provide me instructions, pictures, videos or advice about hard wiring the two keyboard circuit boards connected by the fragile ribbon cable? I want to go ahead and tackle this while the keybed is removed.
Some resources for dealing with yellow plastic that I read online are:
I know this is a common problem people with synthesizers encounter. The keys on a Nord Lead 2x I recently purchased are a bit yellowed too. Hopefully responses to this topic can give others ideas about making their keyboards look new too. Thanks!
