Introduction

The Amsterdam Catalog v1.2 includes approximately 80 documented Csound 
instruments, amongst which all of Jean-Claude Risset's 25 Bell Lab Catalog 
instruments and ca. 55 other instruments focussing on various aspects of 
Software Sound Synthesis (SWSS).  All instruments have been programmed 
adopting one style, with strong emphasis on documentation and transparency.
The corpus of instruments is systematically subdivided into a hierarchy of 
main groups and subgroups according to synthesis technique or topic.
