I've been trying to recreate this sound from a song I made when I was quite young. I used GarageBand for this, not Ableton, but due to the advanced level of Ableton I thought I'd still be able to recreate it. From what I remember, I took some sort of string/bell-type synth and played around with all the settings till I came to this.
I will say, however, despite my initial suspicion of a (pluck) string or bell base sound, I haven't made any success with either. The farthest I've gotten was with the muffle, but clearly there's more to this sound than a muffle.
