I just finished my book about the Eigenharp.
With the advent of the Workbench tool in Eigenlabs version 2 software there is now a great way to explore the setups that configure the instrument visually.
While workbench is primarily a tool for creating setups, it can also provide deep insights into any existing setup.
One of the challenges for people who might be interested in an Eigenharp is that they are difficult to find in a retail setting and, even if you do, there is typically no knowledgable person to walk you through what the instrument is capable of.
My hope is that this free book will help in that regard.
