Yup. I think the preset was called “synth pad” or “string pad”. Something close to that. Totally achievable with fx3. Not in front of unit now but you can get there with Golden Shimmer or Plex Shift in the Plex Delay block as a starting point.I had a synth sound on the ips33b digitech super harmony machine that was really cool for that song.
Sorry that's not helpful though, this post just reminded me of that box.
