I have an old Kawai KX-130 double keyboard with a bass foot keyboard and volume pedal, I have removed the bass pedals and built a housing for the hopes of using it as a trigger for another keyboard while playing bass guitar, I do also have a QX-100 that if the board inside is compatible I would be happy triggering just that. the pedal had a white female 10-pin plug connector and a brown 3-pin male socket at the other end, inside the KX-130 it appears to plug into a grey board with cards, there are also two larger brown boards which appears to go from the two upper keyboards individually and into the grey board, Is there any hope of making this work at all?
Trying an idea, hopefully not a stupid idea!

Hi, I'm sure others here will be more helpful than I. What I know about it: you need something to convert the signal from the pedal's PCB to MIDI. Whatever the ribbon cable was attached to would have done that. If you have that knowledge, proceed accordingly. If you don't, you might have to decide if this kind of project is worth your time, over purchasing MIDI bass pedals, such as StudioLogic MP113, Roland PK5.
Best of luck!

Of course this is a stupid idea, but that doesn't mean you shouldn't do it.
The bass pedals are just simple contact switches. Hmmm, maybe there is some simple CMOS or TTL logic in the bottom assembly, but probably not too sophisticated. You could bypass it if that makes it easier.
I would start with a Teensy Microcontroller USB interface and Arduino software. See the videos like:
Most importantly, I think you should add wheels and remote control, so that you could enter it in BattleBots. Or at least paint it to look like a UFO or a Frank Frazatta landscape. Or paint a big "Taurus 5" logo on the audience side.
The prices for organ pedalboards are astoundingly high. Well, okay, $530 for the Crumar. But still, this project would give the illusion of saving money.
My Hammond L122 has a small 13-note pedal board, and I am such a dork that I cannot even imagine the dexterity required to play them well. I find it mesmerizing to watch people pull it off.
When you are done, you will need a stack of amplifiers and a prog rock band to make it all worthwhile. I think stacks of Roland JC120 amps would be cool.

Wait! This guy has some good ideas!

Destroyer of Eardrums!!!
For this price?
Why bother?
You could buy the Behringer and cannibalize the guts cheaper than you could buy an Arduino and the pcb, and all the necessary components plus a case if you start ordering in. Also, how good are you at microprogramming embedded controllers?
What it looks like to me is a barebones diode switching matrix with maybe a multiplexer attached (probably not). Track down the pinouts with a multimeter and adapt them to anything you can find off the shelf.

this is the exact idea I had along with the issues I have encountered, I was hoping that I could open the Kawai QX and some how plug it into the board in there, but I realized after posting this there is no MIDI on it, thanks for the reply and links, I have another direction to go with this
