Does it need a special midi cord or something?

No, but you gotta build a small piece of hardware. You need a 1k, 220 and 800 ohm resistor, a 9v battery, a midi socket,a 2.5mm plug socket and a pnp transistor

Sounds awesome. I have an Arduino, I might try it. Or even help.

No arduinos involved, but thank you for the offer.

It doesn't work. I will check the signal with a digital osciloscope.

Edit: I think it's the hardware. I don't have a clue

Every site tells me to do it differently

Maybe the signal polarity is wrong (reversed), you could check that again.

Nope I know what's wrong! Midi parameters are 7 bits instead of 8 bits!
The first parameter (command and channel) is 8-bits, but the following two are supposed to be 7 bits long!
