Compatibility issue

[silveruniverse]

Hey,
Would it be possible for this to work on win 7 64bit and/or a PS3 Rock Band 3 keyboard?
I've tried and tried for hours and MIDI-OX does output random instrument change events, but doesn't do anything if I press the keys, only the buttons.

Hi silveruniverse,
I've just tested it on a Windows 7 64-bit system and it works with the Wii
version of the keytar (inc. key events). My guess is that the PS3 version
is incompatible. Sorry :-(

You have this person's email address. Here's an idea. Ask them if they could send you output from another program on your github download area, then if they say yes publish a variation that just records incoming data to a file, and make the binary available for download.

That's a good idea, I might think about doing that.

silveruniverse, I apologise for referring to you in the third person there. The comment was intended to be a private communication. I didn't know my email would end up on this website.

The idea is to see if it's possible to debug your setup by looking at what the app sees from your variant of the keyboard. It could be a quite simple variation that could easily be accommodated by a small change in the code.

Oh no worries, I'm more than happy to help with this, although I lack any knowledge on how to record the data output by the dongle.

But I tired anyway with software called USB analyzer:

Is what it recorded happening when I enabled the rb3_driver application, but even when pushing the buttons and keys the code there seemed to be the same.

If there's anything I can do and if you wish to add PS3 keyboard compatibility, then I'd be happy to help.

Hello, has there been any progress on this matter? I also own PS3 keytar and I would love to help in anyway possible.

Hi folks,
Great project!

I also have a PS3 keytar. I'm looking into it. I can see output for all the buttons in the debugger but nothing from pressing the keyboard keys.

The packet size is still 27 bytes, although the format is a little different from the doc for the Wii version.

I wonder if the PS3 version could use a different endpoint for the keys, or if there is some other difference?

Cheers,
Richard.

On the PS3 keytar, packets from endpoint 0x80 look like this:
00 00 08 80 80 80 80 00 00 00 00 00 00 00 00 00 00 00 00 00 02 00 02 00 02 00 02

Byte 0:
bit 0 (1) - square
bit 1 (2) - x
bit 2 (4) - circle
bit 3 (8) - triangle

Byte 1:
bit 0 (1) - select
bit 1 (2) - start
bit 4 (10) - playstation button

Byte 2: directional pad, 8 = inactive, 0 = up, increasing clockwise

Remaining bytes always static as above, no response to keyboard keys or modulation slider.

Endpoint 0x02 reads out 9 byte values, all 0. Haven't found any other responsive endpoints. Bit of a mystery. Maybe there is a configuration step required?
