Inserting New Software Chips for Software
How to Physically Change Your Software Chip
And the Special Patch Chip
BEFORE YOU REMOVE YOUR SOFTWARE CHIP
Turn on your malletKAT and look at the display. If you see a “+” sign
after the word malletKAT, (malletKAT+) then you should be installing the
20 meg version. Otherwise you will need to install the 16 meg chip. You
MUST install the right chip for the malletKAT to work! Call us if you have
the wrong chip at hand.
One Philips Head Screw Driver
One Flat Screw Driver
1) Remove the power cord, foot switches and any MIDI cables
from the malletKAT. Find a smooth, clean, flat surface and
place your malletKAT upside down, with the jacks facing
away from you.
2) Remove the back cover of the malletKAT, using the Philips
Screwdriver. Notice that some of the screws are shorter
(by the power input and MIDI jacks). Keep note of this when
re assembling the back cover.
3) When the malletKAT is opened, you will see a large circuit
board on the left of the instrument. On the left side of the
board, directly below the footswitch one jack is a large chip
(U8 on the board). There should be a label on it saying the
version of software (i.e. 3.6YS). This is the software chip,
the code that runs your malletKAT- its’ Operating System.
4) Before you take the old software chip out, note how the
chip is oriented in the socket. Specifically notice that there
is a “notch” in the chip on the top part away from you.
This notch tells you which is the top part of the chip when
you install it.
5) To remove the old chip, you will use your small flat
screwdriver. You will want to pry the chip out of its socket.
pry out the socket underneath the Software
Chip. It remains attached to the printed circuit board.
Look now at the new Upgrade Chip you received and you
will be able to tell what is the chip and what is the socket.
You want to insert the screwdriver between the chip and
the top of the socket so as to pry up the chip but not the
socket. You should alternate lifting each end of the chip
until it is free. If you pry out too much on one side, you
will excessively bend the small legs on the other end as the
chip pivots on them.
6) After you have the chip out, place the new chip labeled
in the socket, being careful to orient it in the same
way that the old chip was. (Remember the notch on top?)
Take a little care to align the legs of the chip into the holes
in the pins of the socket. When they are all aligned, gently
push down evenly on the chip. It should push down snugly
into the socket. Visually check to see that none of the legs
got squished and are smashed under the chip.
Replace the back cover of your malletKAT and reinsert the
screws. IMPORTANT- Use only the short screws
under the power jack and footswitch jack.
You don’t want to jam the long screws into the power jack.
A long screw
WILL damage the on off switch or footswitch
8) Turn your malletKAT over; reinsert the power cord and foot
switches and power up. You should see the malletKAT
4.0 software letters. If the display is working,
you are OK. You must now reinitialize your malletKAT. With
the edit footswitch down, hold down both function pads
until the screen tells you to also hold down the adjacent A#
key. Continue holding down all three pads with the edit
footswitch down until you hear the special reboot sound.
You are now ready to enjoy the new software,
IF THE DISPLAY IS NOT WORKING
1) Remove the power cord and jacks again.
2) Turn the malletKAT over and remove the screws and back
3) Try reinserting the chip (pry it out again to make sure that
the legs didn’t get bent under the chip).
4) Put the back cover back on, turn the malletKAT back over,
reinsert the power cord, and turn the power back on.
5) If this still fails, put your OLD software back in and give us a
call at 877-933-6237.
SEND US BACK THE OLD CHIP
After you have had the new software in and used it for
several days, please send the old chip back to us. They are
reusable, and help to keep the prices down.
YOUR EXISITING 3.6 USER KITs and
THE PATCH CHIP 1.0
4.0 software will NOT accept an ALL MEMORY or GLOBAL
dump from a 3.6 malletKAT. It will accept an ALL KITS DUMP but
there is a new development.
The new software has changed the way we name program and bank
numbers. Instead of using numbers 1- 128, we now confirm to the
more widely accepted 0-127 standard. This means that your
program change numbers and bank change numbers will be off by
one when loading in your old kits. You can manually change each
one, or you can use the PATCH CHIP that will automatically reassign
the new values to your old kits so that everything goes back to
normal. The same sound will come up, but with a different (lower
by one) program or bank number.
This chip is necessary ONLY if you have lots of USER KITS from 3.6,
and you do not want to manually change the PC and Bank Numbers.
When updating from a prior release to the
malletKAT 4.0, you
will need to use the following steps in order to modify the program
and bank select values in any saved user kits.
1) Save the USER KITS (ALL KIT DUMP) by sending a data
dump to a sequencer or data filer using your existing
software release. (probably version 3.6)
2) Install the new malletKAT 4.x chip and Reinitialize the
3) Load the old ALL KIT DUMP User Kits back into the
4) Remove the
malletKAT 4.0 chip and install the PATCH
CHIP. Power up the instrument, wait a few moments for
the changes to take place, then shut off the instrument
5) Now reinstall the new
malletKAT 4.0 chip
All of your USER KITS will now work the same, but the display will show
the program and bank numbers to be one count lower
