Expanded Schantz Organ (v 3.0)
This organ is an expanded version of the Hauptwerk "FBR Schantz" organ created by Jonathan Orwig at Evensong Music.

The First Baptist Church of Riverside (FBR) Schantz Three Manual Organ has was an early a favorite Hauptwerk sample set for many years. It is an “American Classic” style instrument with a small amount of reverberation (semi-dry acoustics).

My Expanded Schantz Organ recasts the sampled ranks from the FBR instrument into a larger specification that fills in some gaps in the original. There is, however, no unification in the resulting instrument. The new disposition is quite complete for a three-manual American Classic instrument. It retains a definite Schantz sound while not imitating any particular instrument.

Version 2 of the Expended Schantz Organ has been updated to take advantage of several new features in Hauptwerk 4. It will not run in Hauptwerk 3. If you do not have Hauptwerk 4, you can still run Version 1.2 of the Expanded Schantz organ. Version 2 sports a crescendo pedal, courtesy of Al Morse's software plus my own special software to massage Al's output into the graphical displays I have created. I have also completely rewritten the tremulants.

New features were added for Version 1.2 of this organ and retained in Version 2.0. I have added a borrowed Basson 16' to the pedal to give the user a quieter choice of reed. By popular demand, I have added Swell and Choir Melody couplers. These allow stops from the Swell or Choir to be played together with the highest note played on the Great, providing some interesting possibilities. I also added a Bass coupler to the Great. For those of you who are not great pedalers (or who have to accommodate other organists with this deficiency), this takes the pedal stops and plays them from the lowest note on the Great.

Version 3.0 repairs an error in the swell enclosures that caused ranks to sound brighter when the boxes were closed.

A second version of this organ is now available as revoiced by Mark Williams.

The new "Expanded Schantz" organ has the following specification:

Some borrowing of ranks between divisions was used and this is indicated on the stoplist. The Vox Humana was moved from the Choir to the Swell. The 2’ Principal was moved from the Swell to the Choir. Several stops were created by combining pipes from two of the original ranks, transposing as appropriate, and carefully working the transition notes in amplitude. These new stops are the Swell 8’ Geigen and 4’ Flauto, and the Choir Gems Octave. The Choir 8’ Hohlflote uses the samples from the Swell 8’ Rohrflote. In order to keep them from sounding identical, I brightened the Choir stop and made it a different volume level. Since there is no unification, one can couple these two stops together to create a flute ensemble. I also added the remainder of the standard American Classic couplers.

Since my own touch-screen monitor is only 15” (a size which fits nicely above a side-jamb of a typical organ) all my screens are sized to fit. The resolution is 1024 x 768. Here are the console and stop views:

Here is the crescendo setter page. Simply click on the lights to change them from red to green. Green indicates that corresponding stop will be "on" at the appropriate crescendo stage.
If you want to try this, be sure you first have a valid Hauptwerk license (this organ will not work without one, but it does not require a special dongle file) and have the FBR Schantz organ installed correctly. Then download the following:

1. Download Hauptwerk Installation rar

This is a Hauptwerk standard installation package in rar format. Save it to your disk, start Hauptwerk, and then use its install feature to read the rar file as per the manual.

I have heard from some users (outside the USA) that you might need to disable the "wind model" for the organ to play properly. Since I am in the USA I cannot test this - but it sounds reasonable.

2. Download CODM Source File

This one is optional. I provide the source code for the Hauptwerk editor so you can see how I did all this and get ideas for your own projects. You will have to rename this file after downloading to "Les-SchantzV3.CustomOrgan_Hauptwerk_xml." I could not get the download function to work properly with the new extra-long file extension required by Hauptwerk 4! Since the CODM cannot generate the crescendo pedal, I included version 1.1 of the organ here (identical except for the crescendo pedal). You can add a pedal back using Al's software, but you will not get the same display I have used in Version 1.2.

This organ is an exceptional value. You get ~60 ranks for $100 (I get nothing - but I have great a day job.) The organ is very complete and makes no compromises. It works well with many different genres of organ music. The samples are "only" 16-bit so the entire organ fits easily into a 3 GB system. Remember that Hauptwerk's internal arithmetic is much deeper than 16 bits so the ensembles are accurate to many more significant bits. These samples were recorded in a live acoustic, but the hall is very dry. I add some simple reverb to the organ - either Hauptwerk's own reverb in V5 and later, or software reverb on my Mac. The total effect is wonderful.

Here are some demo recordings of this instrument I have created. I have chosen pieces that show off the many variations in tone color that this organ can produce.
