Well, I have an idea of the technical approach to this. I don't know if your synths can arrange modules serially, but this is what I was doing:
Start with a detuned saw wave (try 10+ voices) on an oscillator. Adjust envelope for attack and release as necessary. Put in an FM oscillator in serial, and do maybe 80% volume on the FM osc. If you have a stereo width knob, make it completely wide. After both of those, add a low pass filter in serial and adjust the cutoff. I'd say around 78% of the way between 20Hz and 20kHz, so about 14~16kHz is where you should stop it. Add some stereo ping pong delay and some reverb with some tweaks. That's the pad layer.
The top layer sounds like a bell-like sound with a reverse effect mixed in at about 50~70%, lots of delay with a very unique characteristic (as in, specific to particular plugins, possibly), and (of course) reverb. I think NastyDLA MKII can do a pretty accurate delay for this ("modulated panorama" preset). Not sure on the top layer synthesis. I don't think it's actually a bell though, and I think the major component of it is the plugin used for the effects. It's probably a plucky sound with some complex harmonic variation on the sine wave (you might actually need to draw your own wavetable, or just find one that is close in tone. Alternatively I think you could layer sine waves of different wavelengths, but that's too much work), using slightly slower attack than a normal pluck (maybe 5%), with its dry mix lowered to de-emphasize the attack, and the wet mix at around 90%.
