Disklavier

Kevin,

Thank you for your awesome software authoring efforts.  I confess that I have not been 
able to get your browser to see my mark IV (even though I can use the To/From PC folder 
with my wifi-enabled computers at home), but I'll give 0.30 a try soon and hopefully that 
will do the trick.

It could be based on your symptom list below that your dealer forgot (or did not realize) to 
calibrate your piano before delivery.  You can perform this calibration yourself (do this at 
your own risk!), as follows (from memory, so pardon the possible errors):

- Quit the interface on the PDA and instead run the Service program, which can be found 
in the main set of PDA program icons.

- You'll see a white screen with about 3 text options, none of which are particularly 
exciting.

- Slide down the keyboard cover on your PDA, and hold the D, M, and P keys down 
together (they don't need to be pressed at the same time, just held down together).

- You should see the service options expand greatly into a maintenance mode-like menu.

- There is an option to perform a "Full Calibration w/GS check"-- GS meaning the 
grayscale sensors.  It's a couple menu options deep, but shouldn't be too difficult to find.
  Run this.

- Your Mark IV will undergo a large number of self-calibrations, which include how much 
voltage is needed to depress the pedals to various extents, how much voltage is needed to 
make each key play at a certain volume, etc.  The calibration process makes a lot of (very 
cool) sounds... so don't start it unless your housemates don't mind a lot of increasingly 
loud piano playing.

- If your Mark IV passes each set of calibrations, it will play a single C-Major chord; if it 
fails, it will play a c-minor chord.  You'll get text messages throughout the roughly 15 
minute process as well.

- At the end, the Disklavier writes all of the newly-derived parameters to a file that is 
used to optimize playback.

I've found this process to be very helpful in getting my M4 optimized; hopefully it will 
help you as well.
