hello,
I am having some trouble with a one-year old midi keyboard (edirol pc300), the keys seem to end up inactive one by one. I'd like to fix it. I opened it to check the contacts.
it appears that mechanism is based upon two areas of two contacts shorted by small conductive "bushes" pressed against the board when a keys is hit.
I guess the velocity info is taken from the time difference between those 2 areas of contact.
I could not discern any visual difference between ok and inoperating keys. Clean the contacts was totally inoperent..
maybe someone has some idea upon this (frequent) problem with cheap midi controllers....
this is my last time with edirol, by the way!
thanks
