Test
The first time you power the DX7 on (and any time you change the battery) you will notice about a
5 second delay before the LCD shows it's initial message. Tense moments indeed.
The LED should display characters such as "--". "C4" and "Su". Eventually you should get
the message like:
The 2 banks of "factory" patches sounds have been copied to all 16 patch memory banks. Please
read the owners manual before reloading your own patches. You can do a quick version check of
the board by pressing and holding the front Function button and also pressing and holding
buttons 16 and 32. You should see something like the following:
NOTE: Rev B also shows the setting of the board mounted velocity switch on this screen. It will
say "Vel=+0" (normal) or "Vel=+3" (offset applied). The units 0 and 3 are DX7 internal values
and have no particular weighting such as MIDI units or dB or anything else. It was chosen so that
a typical player can achieve a MIDI Out note-on velocity of 127 using reasonable force.
Consult the online "Yamaha DX7 SuperMAX+ User Guide" for more information on using
your upgraded
DX7.
Problems?! Almost all installation problems are due to poor board seating or connections.
Remove the board; check all the pins for debris, contamination, bending, etc. Then reinstall.
Battery Holder Option
The information here is deliberately minimal. It is intended that a professional perform the work
for the battery modification.
A CR2032 battery holder is supplied in case you would like to have your soldered-in
battery removed and replaced with a CR2032 coin cell.
If you prefer to install a pair of AA or AAA batteries, such a holder is available by
special request at SuperMAX+ order time.
CR2032 lithium batteries are extremely sensitive to heat and shorting and can
explode! This operation should be left in the hands of a qualified technician.
The tech will remove the old battery and run wires from the old battery location to the new one,
making careful note of correct polarity. It is not unusual, however, to encounter defective
diodes and/or open traces. This work will require the use of a multimeter and soldering iron!
