|I have a Rodgers 3-manual 945 organ. When I purchased Hauptwerk I noticed that there were no free sample sets for organs larger than 2 manuals. I therefore used the CODM to piece one together from three excellent sample sets that are nearly-free to licensed Hauptwerk users: the St. Annes Moseley organ that comes bundled with Hauptwerk, and the Little Waldingfield and Groton organs from Lavender Audio. The Lavender Audio organs are shareware so they are available at a very low cost. In addition you may use them for a limited trial period for free evaluation.
I used the St. Annes Mosley organ for the Pedals, Great, and Swell. I took some of the stops and moved them to a new choir manual. I then used the Lavender Audio samples to fill out the choir.
For version 2, I filled out a cornet in the Swell using some interesting methods. I reused the samples from the Swell 4’ and 2’ flutes to create the 2-2/3’ Nazard. The top seven notes come from the 2’ samples and the rest from the 4’. Since Hauptwerk allows one to create new ranks from reused samples, it is as if the builder had duplicated these pipes and placed them on their own chest. I have returned the resulting “rank” and also carefully balanced the transition between the two sets of samples. I similarly created the 1-3/5’ Tierce from the 2’ samples. The top few notes do not play (they wouldn't likely on a pipe organ anyway.)
For version 2.1, I fixed a bug that caused the "Bass Coupler" to function improperly. In the new version, engaging the coupler correctly plays the pedal stops from the lowest note only of whatever is played on the Great.
I also added some borrowed stops in the Pedal to give it more independence and reduce the need for coupling.
Since the two new ranks are true Hauptwerk ranks, there no is unification, the tuning is correct, and the user can voice each ranks separately (assuming you have the deluxe edition of Hauptwerk.)
The result is excellent and I often practice with these samples.
