Is this Rhodes? With some effects? Sounds so lush, anyone have an idea what is used here and how to achieve this sound? Clean and warm at the same time.
I would start with chorus detuned slightly (or copy your track, and lower one by a few cents, and slide a few ticks timing as well), and a little reverb to taste. You could also use a delay and just keep it super tight. Played in a middle register (not too high).
