I just insert instrumental of the song in fl studio and play single notes over the chords in the song, if the note is not right you will hear that its just not in tune with the chord from the song, and if the note is right you will just hear that it sounds right, and like that note by note. Its best to use headphones while doing it.
Thats dope man, you gotta a ear for it. How did you find those sounds that sounds like those? Are these the original sounds from a synthsizer back in the day?
