Introduction |
This is a guide for disassembling the key panel for the later model Roland KR-33 electronic keyboard which uses flat metal leaf springs for the key return. Earlier models used coiled key-return springs and a slightly different key design. Using this guide you can gain access to the return springs as well as the key membranes for cleaning, replacement, or repair.
A common problem with these keyboards (and the one being resolved here) is dirt in the membrane contacts causing specific keys to play intermittently or stop playing entirely. Cleaning with isopropyl alcohol typically resolves this issue but replacement parts are also available from Syntaur. |
