Hmm ty for sharing this post. I just opened my broken my Xbox Midi adapter, and JP1 and JP2 are both solderer with jumpers. Think it would be as simple as to solderer the jumper(s) onto a PS3/Wii versions to work for xbox? I can provide pictures of it but cant atm.

As many of you already know, there are Rock Band accessories built for PS3 and Wii which share the same hardware. The basic controller functionalities (directional pad, navigation buttons and similar) of these controllers built for Wii work fine in PS3 and viceversa, but the Rock Band specific functionalities (such as the keyboard actual musical keys) do not work if you connect to your console the controller meant for the other system. A conversion however is possible and fairly quick and easy to do, which helps if you have difficulties finding an accessory for your own console.

 

Accessories which are confirmed to be convertible between PS3 and Wii are:

– Pro Keyboard

– MPA (Midi Pro Adapter)

 

In this thread I want to share my experience with converting an MPA for Wii into an MPA for PS3. Please be careful when doing any sort of hardware hack, and accept the risk you might damage your device permanently. I don’t take responsibilities if you do!

 

1) Opening the MPA.

 

The MPA can be opened by removing a few screws from the back of it, however some of these screws are hidden under the tiny circular rubber pads. These pads can be removed easily by hand, and the adhesive below should remain sticky enough to be able to put them back when closing the MPA again, as the process doesn’t take too long. You might have to apply some pressure to the side groove of the MPA to pop it open. Be careful not to pull or rip any electrical wire when doing so! Here is how the MPA looks from the inside.

 

2) Finding the key jumper.

 

All that separates a PS3 MPA from a Wii MPA is a single jumper or zero-Ohm resistor. Presumably, this connects the main board to an additional part of the circuitry. This jumper is present in the Wii version of the MPA and absent in the PS3 version. Notice the set of resistors at the centre-bottom of the circuit board, the key jumper is the one labelled as JP2 with “000” indicating it is a zero-Ohm resistor (or short-circuit).

 

3) Removing the key jumper.

All you need to do to convert a Wii MPA to a PS3 MPA is to remove the jumper. This can be done with a simple tweezers. The only difficulty is to actually grab it with the tweezers, because it is very tiny. Once you get a hold on it, twisting the tweezers with a small force should be enough to make the jumper come off, just be careful not to scratch other parts of the circuit board. Should you need the opposite i.e. to convert a PS3 MPA to a Wii MPA, the task will be more difficult and likely require a soldering iron in order to create a short circuit at the otherwise empty JP2 location. Here’s a picture of the board after removing the JP2 jumper.

 

4) Closing the MPA back and enjoy!

 

Here’s a bonus picture to give you an idea about how tiny the JP2 jumper really is ” data-emoticon=”” src=”/emoticons/default_SA_smile.gif” title=”” />

Hi Shroud,

on your main post you mention that converting Pro Keyboards is also possible. 

how do you do it? there is no JP resistor on the main circuit board on the keyboard or the dongle. 

on a reddit forum I read that you should remove resistor R24 on both the keyboard and the dongle. I did it but had no luck getting the Wii keyboard to work on my PS3. 

thanks

I am afraid I don’t know the specifics of the Pro Keyboard, as I have only ever tried converting the MPA, but I’ve heard many times that people have managed to do it.

I opened up my wii Keyboard but there are no JP1 or JP2 resistor.. THeres is a 0 (zero resistor labeled R24 and (reading other posts on reddit) I went ahead and removed te resistor both on the keyboard and on the dongle, but still cant manage to get them workin on my ps3.

If you have anny idea where could I find such info, id appreciate it.  I-ve searched on these forums and on reddit and cant find any additional info.

Thanks
