Les Productions Zvon has released Composite Bells, a collection of royalty-free samples.
One of the programs for the Cakewalk Rapture version of my Chromatic Hits sample set is made of 3 layers (elements) where the pitch and pan position of 2 of the layers vary randomly on each note on. These variations are made by the audio engine and not via MIDI. This means that the length/playback speed of the samples is altered and gives some interesting results.
Composite Bells includes 25 samples (stereo except one indicated as mono). Anyone having the full version of the Chromatic Hits can create their own similar samples.
You can download the samples here (5 MB, includes a text file with more info).
