Tools to enhance Hauptwerk Organs


This page contains extensions to Hauptwerk organs through manipulation of their Organ Definition Files (ODF), or by compilation of new ones.
A sample set can often be easily customized if the ODF is a standard XML file. If you buy a sample set with an encrypted ODF, you're stuck with what they give you, unless you write your own.
Most of the ODFs shared here began with CODM compilations which were then extended using XML and text editors.

Extended Caen Cavaillé-Coll Organ

This is an extension of the Sonus Paradisi Caen V2.5 organ that adds several stops and an enclosed Positif.
The extra stops are fabricated from original ranks in order to preserve the purity of the acoustic.
Great care was taken to preserve the improved tremulant introduced by SP in ver2.5 of the sample set.

Here is the screenshot for the extended organ.

The layout is simple and readable with stops arranged in a predictable manner per AGO recommendations. This extension includes no extra samples, only a few new graphic images. It requires a prior installation of the full Sonus Paradisi Caen v2.5 sample set from Sonus Paradisi, but is otherwise free.

Here is the installation file. It has the surround configuration and requires as little as 15.1 GB to fully load at 16 bits. As with the Sonus Paradisi version, ranks with "L Component" or "R Component" should be loaded mono to minimize memory requirements
Extended Organ InstallationFile
The organ installs as organ number 001252 and will not interfere with the original installation.
This organ requires Hauptwerk version 4.1 or later. The voicing and tremulants are identical to the original Sonus Paradisi version.
Extensions include:
...The Positif is now enclosed in an expression box
...The Pedal adds a 16' Basson and Principals at 16' and 8'
...The Pedal Contrebasse16 and Violoncelle8 are now enclosed in the Recit expression box
...The G.O. adds a mixture and the Cornet is extended to a full 56 notes
...The Positif adds an Octavin 2' and a Piccolo 1'
...The Recit has an added Prestant 4'
...A Trompette en Chamade is playable from either the Recit or Positif manuals

The annoying ventils have been omitted since a modern combination action renders them superfluous.
Key noises have been recently added. They are on by default but can be turned off by the "sons des claviers" switch.

Note that none of these extended organs include the wind model for users outside the USA. This is due to patent restrictions in the USA.

Extended Three Manual Velesovo Organ

I think the new Velesovo organ from Sonus Paradisi is a fabulous bargain.
In fact, I think it's too good to leave as just the standard two manual baroque organ.
So I have fabricated a three manual version by loading certain ranks multiple times and
spreading them over three manuals.

The extended organ is a three manual contemporary disposition with expressive Swell and Choir divisions, two Celeste stops, lots of couplers, and a Crescendo pedal. In spite of that, it is still pure Velesovo, using only Velesovo samples that are somtimes loaded multiple times with appropriate custom voicing changes.
Here is the screenshot for modern three manual extension of the Velesovo organ.

It has a simple, readable layout with stops arranged in a predictable manner per AGO recommendations. The ODF is formed in CODM with post-processing which adds the multiple releases and Crescendo pedal. It requires a prior installation of the full Velesovo sample set from Sonus Paradisi, but is otherwise free.

Here is the installation file. It has the surround configuration and requires about 10.3 GB to fully load at 16 bits.
Modernized 3M Organ InstallationFile
The organ installs as organ number 001244 and will not interfere with the original two manual baroque installation.
The goal of this extended organ is an instrument comparable to a typical modern organ which is useful for more than just baroque music. The exclusive use of Velesovo samples retains the clarity and acoustics of the original Velesovo organ. Here is a demonstration using the celeste, expression, and the Crescendo pedal near the end. Elgar-Nimrod

This organ requires Hauptwerk version 4.0 or later. The voicing, short release timings, and tremulants are identical to the original two manual Sonus Paradise two manual version.

Note that none of these extended organs include the wind model for users outside the USA. This is due to patent restrictions in the USA.

Extended Version of the Laurenskerk Marcussen Demo Organ

Sonus Paradisi has very generously provided a very functional, surround sound, demo version of their large Rotterdam Marcussen organ. The demo sample set has enough ranks to be playable by itself, but can be extended for more flexability by loading certain ranks multiple times and spreading them over three manuals with a convienient AGO layout. Additional sounds are created by changing various rank voicing parameters. Two of the 16' pedal stops are twelve note extensions of 8' manual ranks. These extensions were formed by synchronous FFT translation.

Here is the organ installation file. It is a reasonably small 90MB because (other than the 12-note pedal extensions) it relies on samples from the Sonus Paradisi Demo Laurenskerk surround sample set (which must be previously installed):
InstallationFile
The new installation installs as organ number 000755.
Since a new and unique organ number is assigned, the original Demo installation from Sonus Paradisi
is not affected in any way.

Hauptwerk version 4.0 is required to use this extended sample set


Extended Three Manual Menesterol Organ

The Menesterol sample set from Sonus Paradisi is a real bargain. The sample set comes in Dry, Moist and Surround Sound, all included for a single very low price. I prefer the wet surround sound but like more flexability than afforded by the included two manual 23 stop version.
A 37 stop, three manual version can be formed by loading certain ranks multiple times and spreading them over three manuals. Each manual division has an independant tremulant, and two are expressive. The sound is essentially similar to the original version if only the original stops are used, but additional sounds are created by changing various rank voicing parameters.

Alternate Stop Layouts for Historic Organs

Sample sets for Historic organs usually provide an on-screen stop layout which is faithful to the actual organ console. While this is intersting to study from a historical perspective, I find it extemely annoying while actually playing the instument. Stop knobs on the real instruments are evidently determined by mechanical considerations of the action. The result is often an illogical layout that makes no sense for musical registration purposes. One can certainly get used to any layout, but if you have several such organ sets, and play each one only occasionally, it's not worth the confusion.

The following versions of popular organs arrange the stops according to AGO conventions and sometimes move or duplicate ranks to more conventional (and useful) divisions.

St Maximin AGO

This is a three manual rearrangement of ranks in the four manual St. Maximin organ. The original organ has a stunning sound but can be difficult to play because of an extremely confusing and unconventional placement of ranks and controls. This version retains the quality of each rank's sound but rearranges them for a more flexible disposition in an AGO layout.

mounted

The installation file is very small because it uses samples from the Sonus Paradisi
version of the St. Maximin surround sample set (which must be previously installed):
InstallationFile
The new installation adds a few new images and installs as organ number 800800.
Since a new organ number is assigned, the original St. Maximin Surround installation
is not affected in any way.

Flentrop (Zwolle) AGO

This is a three manual rearrangement of ranks in the four manual Zwolle organ. The layout of the original organ is reasonably logical, but there are too many stops for my computer and three manual console. Also, I find the ventels extremely annoying. This version chooses stops that I most want in my three manual setup, rearranges them in an AGO layout, and eliminates the ventels.

mounted

The installation file is very small because it uses samples from the Sonus Paradisi
version of the Zwolle surround sample set (which must be previously installed):
InstallationFile
The new installation adds a few new images and installs as organ number 001245.
Since a new organ number is assigned, the original Zwolle Surround installation
is not affected in any way.
note: This ODF only works with Zwolle version 2.0 and not with the newer version 2.5

CODM Example (Prague Baroque)

This is an example of an alternate layout using the Prague Baroque sample set from Sonus Paradisi. This is not an extended version of that organ, but places the stops in a new layout using CODM.

mounted

The download file is very small because it only uses samples from the Sonus Paradisi
Prague Baroque Wet sample set (which must be previously installed).
After installation there will be a new 800371 folder in the Hauptwerk "OrganInstallationPackages" folder. This new folder contains a few images and the CODM file. The CODM file is called "PragueBaroqueOrgan371.CustomOrgan_Hauptwerk_xml". It is convenient, but not necessary, to copy the CODM file to the "CustomOrganDefinitions" folder which is under the "HauptwerkUserData" folder.
The file can then be compiled by opening it with the Hauptwerk "Design Tools\Load Custom organ" command. The new organ will be called Prague371:
InstallationFile
The new CODM organ installs as organ number 800371 and will not affect the standard Prague Baroque organ installation in any way.

Modification of ODF's

It's sometimes desirable to customize the ODF of a sample set.
This is usually required in order to make optimal use of organ MIDI hardware when it does not exactly
match the software representation in the commercial ODF.
Modification of an ODF requires use of an XML editor and/or a good text editor.
I use XML Marker and Ultra-edit.

Diagnostic Tools

I sometimes need a pure sinewave stop to evaluate my audio system.
When a pure sinewave stop is loaded into a CODM organ you can quickly sort out the frequency response of your audio system as well as locate any gross peaks or valleys due to the audio system or the room acoustics.
I have two ranks of pure sinewaves: "Sine16", a 61 note rank at 16 foot pitch that can be used as a stop on a manual keyboard, and "Sine32", a 32 note rank at 32 foot pitch for use with the pedals.
These diagnostic ranks are available for download as self-extracting RAR files.
