Midi Imputs

Hello, I've used a lot of midi drivers and inputs on my computer, and nothing has gone wrong. I also plug in my piano to musescore. Then something went wrong.

I downloaded this midi driver to play my midi files from musescore to multiplayerpiano.com using a bot. (That's why I needed the midi driver) Then, after that, smooth sailing. I didn't download anything else midi driver or midi related after. I plugged in my piano using a USB port, like always, (getting ready to use musescore) and I used GarageBand to see if it is connected, then I opened musescore, and tested to see if it detects the notes I played, it didn't. I thought to myself, "This happens every so now and then.", so I closed musescore and re-plugged in my USB midi chord thingy-ba-gingy. It still didn't work, I tried it numerous times checking to see if there were ANY problems. I came to the conclusion that it was the midi driver, as GarageBand, ever since the midi driver was installed, detected 2 midi inputs. I deleted it but it still does not work, And GarageBand still detects 2 midi inputs! I need help solving this one.

Thanks,
Scilent
