How to fix a stuck kbd velocity of your Roland E36

This page (as you may have guessed from the link you just clicked to reach it) is dedicated to all of them who are the happy buyers of a Roland musical keyboard. I tested what I am going to suggest you with my E36 model, which doesn’t mean it’ll work on yours, especially if it doesn’t support Kbd Velocity mode


Ok, let’s come to the tech details.

The Kbd Velocity mode, from what I could guess when disassembing my KB, works by measuring the time interval which occurs between the contacts of two little switches associated with the key, located at different distances from the fulcrum of the key itself. Now, these are the ones which are messing when your Kbd Vel mode doesn’t work as it should. So, AT YOUR OWN RISK:

  1. unscrew the lower panel of the KB, keep the screws in a safe place (you never know, your cleptomaniac cat may be purring around), then, keeping the KB upside down on a firm surface,
  2. remove the few screws which fix the key-panel to the main chassis, and
  3. pull it out gently from its place, be careful to the flat cable between it and the main electronics
  4. locate the key giving trouble, and
  5. remove it (c’mon, do you really want me to tell you how to do this? Ok, only one hint: first of all, remove the spring)
  6. check the plastic grey sheet covering the contact under the key, which had two small buttons
  7. gently pull the plastic sheet from the electronics panel, and blow (yes, blow) under it, to remove every dirt which may have gone there. Also, you can use a small clean wad of cotton to dust it.
  8. now, from step (6) downward to step (1), do exactly the opposite of what is said, and you’ll have your E36 fresh as a daisy, and working.
