It probably won't work very well with any keyboard that has conductive rubber type key contacts, as you find on all Casios and other cheap portable keyboards. The contacts themselves have a certain amount of resistance, which not only varies from key to key, but can even vary depending on how hard you press down on the key. This would wreak havoc with the tuning of your nice matched 100 Ohm resistor string. I think you pretty much need to use a keyboard that has clean metal contacts and offer near zero resistance if you're going with a resistor string.<BR>

Has anyone around here been successful making a reliable resistor ladder keyboard with a rubber contact system?</FONT><FONT COLOR="#000000" FACE="Geneva" FAMILY="SANSSERIF" SIZE="2"></FONT></HTML>
