sounds like a generic bell patch. Add reverb and possibly some shaping and you are there.

Thanks, yeah looks like you're right! Btw, what do you mean by shaping? EQ?

chorus, detune. stereo, release, decay, etc

As an example, in the real world not all bells would be equal so detuning one of the voices by a small percent will help as well.

It sounds like an FM synth patch to my ears, maybe a DX7 Bell or something similar. As Chris mentioned, you could get there with the right sculpting of nearly any synth bell patch.

er, isn't he playing a Korg something?
It's a Korg N364 from the 90s, and the preset is 38 TheGamelan, which is a kind of multi timbral percussive ethnic mix - the bell sound I suspect has just been isolated and used without the other stuff. You might find the same timbre in other gamelan sounds on other makes.

The video you linked to was a bit blurry but I found the same band on another at better resolution so I could read the label! This site http://www.synthmania.com/n-364.htm lets you hear the presets - look for the gamelan, and about half way through are what I think are the same bells. They're in that synth, just a case of finding them. They could be in another preset untangled by the other gamelan sounds.

If you go down the screen you can hear lots of other very similar sounds.
