Rout Soundfont Loader is a great tool for importing some fresh sounding samples into buzz. Soundfonts are actively traded around the net and there is wide selection of instruments and sound effects in the .sf2 format. To use it, just load it up on the machine window, then right click on it and choose "load...". Then right click again and choose "info on preset" to figure out what bank and patch number you will input in the pattern editor.
