How to change every instance of one note in Sequencer Mode

[Keyboardie]

Ok. Does anyone know how to change one note in a recording, every time it plays and in any octave? For instance, I made this recording of a song using only the notes in the c major chord.

Now let's say I would want to change every instance of the note E (whether it's E4, E3, etc.) into a Eb to make the whole song in C minor. Anyone know of a way to do that?

I forgot to mention this is on a Korg Kronos

Use the search a replace function either in your sequencer or a DAW to replace all the notes in one octave, then repeat for each other octave.
