Start: 9:00am

• Finished the diagnostic sketch
• Had lots of trouble with the addressing of the i2c rheostats.  I forgot that the arduino drops the left most bit because it automatically takes care of the read/write bit.  I found my blog entry which reminded me.
• the registers sub address are 0x80 or 0x00.
• The secondary register circuitry was wrong.  It was attached on the wiper side instead of the power side.
• reordered the speaker wires so its easier to tell which amplifier knob goes to which finger.
• Got 4 fingers working.  The last one is not getting the proper voltage rating from the control voltage divider.
• currently each midi is producing a constant tone for testing purposes on both left and right.  Once I get the left and right to play independently I can experiment with pitch bend and different tones per finger.
