Almost all of the companies whose websites are listed below have provided information used on this website.  Their assistance is appreciated and gratefully acknowledged.

The first site below is the work of just one person, François Demont, who researched and designed his website over several years, collecting over 250 instruments, all without a financial motive.  The results are really impressive.

This extensive, detailed website was created by François Demont and is a must for any Harmony/CMI fan.
