kb fix

This is what I discovered to be the problem for the constantly sounding tone. Somehow the contact under the offending key got stuck. Now I need to look at the power keyboard to see if there are similar problems. Still to be determined is the problem with the missing tones. I will remove the buss bars to see what they look like. Typically a single missing tone is the result of a single bad contact, a broken wire in the wire harness, or a broken resistance wire. To determine if the missing tones are coming from a TG issue, you can listen to the tone that corresponds to the offending key. You can also look at the tone mapping for the keys and see if the same tone is missing in several places. Keyboard tone map: http://www.dairiki.org/hammond/wiring/
