Hello @cabelindsay, thanks for your kind comment, the suggestions are important and more, when they come from someone who knows music like you, I record the songs with my cell phone and yesterday I tried to control the track of the song, but when I lowered the volume there is parts that cannot be heard, but I am already doing the errands for the purchase of a condensed microphone, which they call intelligent, that allows to control the voices and the track. Now when I accompany myself with the cuatro this does not happen, true friend I am grateful for your suggestions, the microphone is expensive, but I will make a sacrifice because it is necessary, I see that many in the community have this type of microphone, thank you, God bless you .
