this is very interesting and yes i know arduino boy is more practical this was just a silly idea i came up with

Ah yes, I did (almost) this about 10 years ago. I wrote a program that would take MIDI and output either sync or keyboard data, through either a "noicash" type cable or a PC Linker cable. If the MadCatz cable is identical to the PC Linker cable internally, this program should just work. Good luck finding a copy (I'm not sure if/where I have one any more) or getting it to work on a modern computer. (It's written in 16-bit Visual Basic 3.0 and requires an LPT port access driver, like UserPort. It may also fail just because your computer is too fast.)

However, I would recommend just getting an Arduinoboy, LSDj-MC2 or mayeb the sleek and sexy Nanoloop USB MIDI adapter: This last one doesn't support keyboard mode, however.

That's an interesting idea, but I'm not sure how practical it is.

Lots of other ways to do this already exist, and most of them are simple and well documented; examples include Arduinoboy and the nanoloop to MIDI adapter. You'd be able to use either of those to achieve what you're describing much more simply.

EDIT: I don't know a lot about the MadCatz Camera cable, but I'm under the impression it emulates something like a printer or scanner on a parallel port—it's not designed to use the same sort of communication protocol as MIDI equipment.

(I have a bad habit of editing my posts to add secondary points, don't I?)

i just thought of the weirdest thing ever. what if we could use the madcatz gameboy camera to pc cable as a midi type sync for lsdj or maybe even send notes to it like the keyboard mod? i dont know how these things work so idk if its possible i guess that'd be my first question xD
