The problem is in the board manager. you probably installed deauther esp8266 boards 2.7. x ver. It will work with Deauther ESP8266 Boards ver.2.0.0

thanks. But I was interested in exactly the channels of the breakdown. I used the program MidiEditor and could not split one channel into several. I'll try the program that...

it is one channel that can be divided into several channels. What is the best way to do this?

What does this command mean? `n>=12&&n

Constantly says "insert sd" what to do?

sorry. After I wrote a comment, I installed sd 16 gb and everything worked. I thought 2 gb was necessary

I have a 16 Gb card divided into 2 partitions, one of the partitions is 2 GB.
