So I just made some chords using a synth and found it could even be used for a melody. The I just copied the top notes in the every chord and pasted it up an octave. Then I just edited them into a sort of mini chord progression(a melody) and it sounds pretty great. And it got me thinking, do we always need the melody in a different instrument?
Of course not. For hundreds of years people have been playing complete tunes, melody and harmony both, on things like harpsichords, guitars, pianos, harps etc. No reason it can't work with synths too.
