Just plugged my 2001 into my rack power for the first time and immediately fried the 10R resistor FB2. Any suggestions on where to start debugging?

Maybe a good start here

Iām a dumbassā¦ turns out I had 4066 chips in all of the TL074 slotsā¦

Replacing R58 with 1K over 10K as advised seems to have cured some or most of my odditiesā¦
Strangely ( or is it normal ) I canāt use the pads without grounding myself to the Panel?
Bring back the Kosmo play set!

Why stop at 80cm?
My case is 60x100

Usually an op-amp plugged in reversed. Common dim light snafu
ā¦or a 4066 chip in there 
I finally got around finishing my #2001, but the touchpads donāt work.
I tried to raise the threshold value in the code from 800 up to 1022, at 1023 it just makes a constant signal of itself. Or is there a value in between that might work?
- So the gate jack and the LED are functioning.
I hooked up my multimeter to the resistors on the main board and tried the connection of every single pad.

The pads all have a connection to the main board, thatās not the problem either.

i tried two different arduinos, one model which drives my 1222 VCOs flawlessly, all the same with both
Do i miss something?

Perhaps your hands are very dry and you are not conducting. Iāve literally connected to 125v AC before and only felt a low V nasty wiggle ā maybe 30-40VAC because my hands were so dry.
Just a thought and possibility
Yeah, that was the reason i fiddled with the threshold setting in the code to begin with, because my fingers are incredibly dry. There is even that line in the code that literally says āgo for a higher number for more sensitivity if you have fingers as dry as the saharaā.
When i was a child, i had an old TV that had conductive pads instead of switches on the front. Those worked fine. Granted, iām not young anymore, but i have two modern lamps that work on the same principle, which are reacting just as they should.
I donāt know man. Maybe tomorrow, i try creaming my hands before trying again. Who knows, if that actually works, iāll let you know.

ā¦or a different resistor value for the pads. a little less than 10M?
A mystery.

Are those resistive or capacitive touch sensors? I think capacitive should be less sensitive to biological differences. 2001 uses resistive, right?

I think 2001 is capacitive. I should look at the code to be sure.

Confirmed that it is capacitive sensing. Also, the code could use some improvement, such as using the capacitive sensing library from Paul Stroffregen.

Anyone willing to incorporate that code?
Iām not so good a candidate

I will when I build mine, but I am not sure that I will get to it soon.

Hereās a decent first hack at capacitive sensors.

Subtle prod to Sussmayr, āLook dude, you can deal with this if you just try. You know you want to. Itās not rocket science.ā

Interesting.
Higher value resistors with the bare metal pads means MORE field sensitive, Lower value 1 MEG means less sensitive.

Update: Iāam a complete moron, and because itās been months since i did this, i didnāt even realize it.
Apparently, i was in such a rush to finish the board, and there were so many 1K resistors, that i just applied them to everywhere, includingā¦you guessed itā¦THERE! xD
The Pads work now, but, while the first five change in tonality, the last three all do the same (frequency?!) if i use them to play (āPads Gateā to 1222 VCOs ālv/octā)
