Help needed on a minor keyboard problem	IIx Owner	2005-01-22 19:30:58
Some keys on my IIx are functioning intermittently. Sometimes they work and sometimes they don't. Each key group (attached to one PCB module) has keys that work and some that don't, so the problem doesn't seem to be with the modules. I have disaasembled the keyboard unit and checked the contact springs. They are all correctly attached and hitting the 5v brass bar. Is it possible they are dirty? How would one clean them? Is there a replacement for those springs? Any other ideas? Thanks.

I cleaned all the springs and the 2 brass bars on the CMI 11 board underneath the keyboard. As I play the keys, I will hit one that doesn't sound. I continue to play and when I hit another one that doesn't sound, I go back to the original non-functioning key and it will work. Each time a key doesn't work, the key that didn't work before will then work. If you can offer any guidance or isight, please help. I am out of ideas. : Some keys on my IIx are functioning intermittently. Sometimes they work and sometimes they don't.

Might help you to connect a MIDI keyboard to the CMI, then see if the same happens?.. If so then its not got anything to do with the CMI Keyboard. Then What?

This sounds more like a problem with one of the voice cards. As you probably know the voicecard that actually will play the note is selected from the "free" voicecards. I had something similar when I had a faulty voicecard. I think on one of the testpages you can actually see which card is selected and thus track back the one that might be faulty.
