Hello! A simple variant might just be to use the multi_voice_chorus ladspa-plugin. I tested it mostly with instruments and there it sounded good. It is in the swh-plugin set from Steve. If you don't already have them, you can find them at: htthp://plugin.org.uk If this plugin doesn't suite your task at hand, you might have great fun with them anyway. I hope that can also be of some help.
