I assume you're indeed talking about a belltree (like this:

(http://www.cottagesoft.com/~songbird/perc/chimes02.jpg) or so... I remember
quite some people mixing them up.

In case you need some chimes, here's some unsorted ones:

(quality is 96kbps/mono, which is as good as 192kbps/stereo)

Sorry, there's nothing like the standard glissando down effect, but maybe
you could edit things a bit. Also, recording quality isn't exactly superb,
but hey...

Cheers,
