Problem to reload the code
Hello I followed the instructions you have detailed and everything works perfectly for me. The problem comes when i want to add more code to the board when the ATMega has already been updated, when i upload the code in the arduino ID it gives me error and does not let me. In the last part of your instructions you say that to put the code back you have to do it with the previously downloaded arduino fireware is only codes of numbers and letters and i do not understand it I hope it will help because i only need that to complete my project Sorry for my bad training, i have started this project for a very short time Thanks for your time Greetings
You've probably followed the instructions for using Flip or dfu-programmer to flash the MIDI firmware arduino_midi.hex. Now you have to follow the same steps, but using the file Arduino-usbserial-atmega16u2-Uno-Rev3.hex instead of arduino_midi.hex. (In step 5, where you load the HEX file.)
Done the steps that you indicate and when i give it execute in FLIP, I get an error in verify and it. doesn't let me load any code. Will i have to update the ATmega before those steps that you indicate?
I realized that the resistor has not benn welded from the back. Will it have something to do?

Please be more specific and post the exact error you're getting.
Did you enter DFU mode by resetting the ATmega16U2?

No, this is only necessary on Rev1 boards.

This is the error that appears when i try to upload the code to the board
Yes, I know that, but did you flash the Arduino-usbserial-atmega16u2-Uno-Rev3.hex firmware using Flip or dfu-programmer?
You cannot use the Arduino IDE unless you're using the Arduino-usbserial-atmega16u2-Uno-Rev3.hex firmware.
yes i did but as i told you before, when i flash it gives me an error in verify and appears in red
Error in FLIP
Did you select the right HEX file? The filename seems wrong.
If it keeps failing, it could mean that the memory of the ATmega16U2 is corrupt. In that case you could try uploading the combined firmware (USB Serial + DFU) using an ISP programmer (using avrdude, not Flip), but it's most likely a hardware failure, so there's not much you can do about it.
Yes ,select the correct HEX and it gives me that failure. I'll try AVRDUDE. THANKS
it keep telling me this error, how to fix it please? exit status 1 'NORMAL_ENCODER' was not declared in this scope
@M1nCh3 This has nothing to do with the question at hand, please don't hijack issues, and open your own. If you do, post your full code.
My arduino seems to be damaged, i've tried another one and it worked for me, Can i do this process with a Mega arduino? because i want to do my projectwith a Mega. I would like to know if an LED can be turned on when i press a button and the LED stay on until i press the button again and it turns off
Yes, you could use a Mega, but I wouldn't recommend it. Using an Arduino with native USB MIDI support will be much easier.
There's an overview of Arduino boards and their USB MIDI capabilities here: MIDI over USB
I would like to know if an LED can be turned on when i press a button and the LED stay on until i press the button again and it turns off
Yes, this is possible using the Control Surface library. MIDI Controller doesn't support it.
Hello again, i am going to take a risk and will mount it with my Arduino Mega, i would like you to tell me how i can increase the codes of potenciometer and buttons , and tried to copy and paste the codes by changing the pins andwhen i have more than two it gives me error. i have no idea about codes , i hope you help me thanks
Please post the code you want help with, as well as your best attempt and the error message you get.

Please note that the MIDI controller is no longer supported, and has been obsoleted by the Control Surface library.
The problem with your code is that you are creating two variables with the same name. This is not allowed.
It's best to create arrays instead of using a separate variable for each MIDI element:
