<DIV><FONT face=Arial size=2> I have a rather fundamental
question. In a keyboard controller resistor ladder, does the high voltage side
go to high pitch key or the low pitch key. I have been tinkering with an old
keyboard and soldered up a 100 ohm resistor between each key for a
nice ladder when it finally dawned on me that I had not a clue which side to put
the current source on and which one to ground. Thanks for your help</FONT></DIV>
