I flashed the MIDI app onto the SAMD QT Py, and all the NeoPixels work, and all the other keys work...

#

Have you double checked the wiring?

#

Since I checked, I obviously missed it. ๐Ÿ˜„

#

No hints?

#

columns are inputs and raws are outputs right ?

#

all keys in the row would mean, maybe the key shorts the power and col pins ?

#

I used this wiring diagram, so where would the short be?

#

blue/yellow on row 1 or col 2, then?

#

oh, you said power

#

so row 1, col 4

#

thanks, @latent spindle, will check my soldering

#

I'm not sure, I'm not very familiar with keyboards, you could post a picture of the back of the faulty key to see if we can see a problem with it

#

will do

#

I had some solder spill into the OUT hole on R1C4, tried cleaning it up... could that be it?

#

none of the other keys on R1 cause this to happen, btw

#

I may have found the culprit

#

my eyes are not very good, but... lemme see if I can get it with the camera on my phone

#

There's a wire stand touching the chip

#

OK, I am getting closer. Thanks, y'all.

I cleaned up the issues indicated above, also had to actually replace the ribbon cable that was bent. Once I replaced that last part, everything started working!

#

ah I was away, glad it worked out !

also, I need more magnification... ๐Ÿ˜„
