Enlarged and/or Enhanced Sample Sets

Efforts to make a good thing better


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.
Some of the older ODFs shared here began with CODM compilations which were then extended using XML and text editors. More recently, the extended Caen, Rotterdam, Zwolle and Dom Bedos organs use the original ODF with some aditional code for the new stops and functions.

Some of these extended organs do not yet include the wind model which has just become available for users in the USA. The Extended Caen, Rotterdam, Zwolle, Rosales, and Dom Bedos organs have been upgraded to include the exact Sonus Paradisi wind model as well as exact voicing of the original stops. The older extended organs were compiled from scratch using CODM and ignored the wind model since there was no way for me to test it. I intend to add the wind model to the other organs as time permits.

Rosales Opus 11 Customized and Extended Organ

The Rosales sample set from Sonus Paradisi is a wonderful modern organ installed in a Portland, Oregon church. This is an excellent sample set as delivered, but there were a few things that I wanted to change for my own use. First, although this is an American organ, the simple screen is delivered with a European layout scheme. American organs have stop layouts per the AGO standard. i.e. Pedal on the far left, and Choir or Positive on the far right. Additionally, we expect the reed stops to be above the flues, and reed and flue stop groups are ordered with lowest pitch at the bottom. This organ has an alternate AGO simple screen added to the nine screens in the original Sonus Paradisi version. I also added four new stops which I think allow the organ to play a wider range of music. These changes are direct modification of the ODF (not CODM) and thus preserve the exact voicing, tremulants, and wind model of the original sample set.
Changes include:
    ...An AGO "Simple Screen" in addition to the original Simple Screen,
    ...The Positive is now enclosed and expressive,
    ...A strong "Trompette en Chamade" playable from the Swell manual,
    ...An "Unda Maris 8" added to the Positive,
    ...Two new expressive pedal stops borrowed from the Swell division.
    ...A 4' coupler is added to the Positive division.


The two new ranks are made from the original organ samples and the acoustics remain authentic to the original sample set. The "Trumpet en Chamade" is a rescaled and revoiced copy of the Great Trumpet8. The "Unda Maris8 is a detuned copy of the Great Bourdon8.

The extensions only appear on the "AGO Jamb" page. All other screens and functions are unchanged. The installation includes no extra samples, only a few new graphic images. It requires a prior installation of the full Sonus Paradisi "Portland Rosales opus 11" sample set from Sonus Paradisi, but is otherwise free.

The two new manual stops control independant ranks. Although they are formed from existing samples, the new ranks are completely independant and may be voiced or tuned without affecting the "parent" ranks. For example, the Trumpet en Chamade8 can be voiced using Hauptwerk's built-in voicing facility without any audible impact on the Gt-Trumpet8 rank, from which the samples are borrowed. Hauptwerk's random de-tuning process will also affect the ranks differently, so this is preferable to an expansion technique which simply duplexes old ranks to new stops. The "Trumpet en Chamade" gives the organ new authority for trumpet voluntaries. The "Unda Maris" adds a lush, romantic celeste sound which was missing from the Positive. The expressive pedal stops give an improved ability to control overall volume of Pedal+Swell registrations.

Here is the installation file.

The organ installs as organ number 001259 and will not interfere with the original Sonus Paradisi installation.
This organ requires Hauptwerk version 4.0 or later.
note: The new version with enclosed Positive was completed 11 August 2017.
         The Positive 4' coupler was added 10 November 2017.

Dom Bédos Customized and Extended Organ

The Dom Bedos sample set from Sonus Paradisi is a wonderful modern build in classic French baroque style. Unfortunately, the sample set was released before the advent of "simple screens" and the photo realistic stop boards are very confusing and hard to read. This organ has an alternate simple screen added to the original Sonus Paradisi version and adds several useful extensions. This is a direct modification of the ODF and thus preserves the exact voicing, tremulants, and wind model of the original sample set.
Changes include:
    ...A "Simple Screen" in addition to the original confusing stop board,
    ...Six new stops added to the pedal,
    ...The Résonance Grand Cornet V which was muted is now playable,
    ...The lowest C# on all manuals is now playable
            (Evidently Dom François Bédos did not think that they were important,
             but most of us expect all the keys to play.)
            (This is a software change. No new samples were required.)

Since these extensions are made from the original organ samples, the acoustics remain authentic to the original sample set.

All the new stops control independant ranks. Although they are formed from existing samples, the new ranks are completely independant and may be voiced or tuned without affecting the "parent" ranks. For example, the Pedal Basson16 can be voiced using Hauptwerk's built-in voicing facility without any audible impact on the Res-Bombarde16 rank, from which the samples are borrowed. Hauptwerk's random de-tuning process will also affect the ranks differently, so this is preferable to an expansion technique which simply duplexes old ranks to new stops. Here is the installation file.
Extended Dom Bedos Organ Surround Installation File
The organ installs as organ number 001258 and will not interfere with the original Sonus Paradisi installation.
This organ requires Hauptwerk version 4.1 or later. The voicing, tremulants, and wind model are identical to the original Sonus Paradisi version.

Extended Caen Cavaillé-Coll Organ

This is an extension of the Sonus Paradisi Caen V2.5 organ that adds several stops, an enclosed Positif, and Tremulant on the Positif.
The extra stops are fabricated from original ranks in order to preserve the purity of the acoustic.
The extended version of the organ is directly derived from the Sonus Paradisi ODF and thus preserves the rather complicated wind model as well as the exact voicing and tremulants of the original stops. The original Anches action has been preserved and improved upon. There is now an "Auto Anches" button which engages all of them at once. This button defaults to the "On" position.

The layouts of the extended screens are simple and readable with stops arranged in a predictable manner per AGO recommendations. There is a new single simple screen as well as dual split screens with all the extensions.
All the original screens are still available and the organ can be played as if in the original Sonus Paradisi v2.5 version.

Here are screenshots for the new simple screens of the extended organ.

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 16 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 4.2 or later.
Extensions include:
...The Positif is now enclosed in an expression box
...The Positif has Tremulant added
...The Pedal adds a 16' Basson, 16' Principal, and 10 2/3' ContreQuint
...The Pedal Contrebasse16, ContreQuint, 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 strong Trompette en Chamade is playable from either the Recit or Positif manuals

The annoying ventils are now more tolerable since the Auto Anches button can be used to turn all of them on at once.
The Positif tremulant, extended split screens, and other minor fixes were done in October 2017. The current version is now 1.6.

Modified Caen Cavaillé-Coll Dry Organ

This is slight modification to the Dry version of Caen v2.5. It adds an enclosure and tremulant to the Positif. There are no stop extensions. There is not much justification for it, but since it's done, here it is for anyone else who might find it useful.
This is just another Caen Dry ODF and does not add any other files to the Caen Dry version 2.5

Here is the screenshot.

The only visual change is to the Simple Screen. There is an extra Expression Pedal and Tremulant Control visable at the lower right. Not many people will want to use this since the Wet Surround version of Caen has such a wonderful acoustic. This extension requires a prior installation of the full Caen Dry v2.5 sample set from Sonus Paradisi, but is otherwise free.

The organ installs as organ number 800822 and will not interfere with the original installation.

Extended Rotterdam Transept Wet Organ

This is an extension of the Sonus Paradisi Rotterdam Transept organ Wet varient (2-channel stereo). It adds a strong solo trumpet stop to both the rugwerk and borstwerk, and a Fagot 8' to the pedal. The original wet Transept organ set lacks a strong solo trumpet which is needed for trumpet voluntaries etc.
In this extension, the solo trumpet (Trompet Grote) is fabricated from the existing Hoofdwerk Trompet with changes to the volume, scaling, and voicing. Since it comes from an original rank, the acoustic is authentic. The 8' pedal Fagot is a revoiced copy of the rugwerk Dulciaan.

At this time, the layout is only available for the "Simple Screen" because that's what I use. This extension includes no extra samples, only a few new graphic images.

Rotterdam Laurenskerk AGO Customized and Extended 3 manual Organ

This organ has an alternate AGO simple screen added to the complete Sonus Paradisi Rotterdam Laurenskerk main organ optimized for 3 manual use with a few extensions. This is a direct modification of the ODF and thus preserves the exact voicing, tremulants, and wind model of the original sample set.
Changes include:
    ...The Rugwerk is now under expression,
    ...Reduced Borstwerk and Chamade divisions in order to reduce memory requirements and required keyboards,
    ...Couplers are added such that two remaining Chamade stops are available to all manuals,
    ...The two included Chamade stops are no longer split to treble and bass,
    ...Two soft, expressive Bovenwerk stops are newly available to the pedal.
Since these extensions are made from original ranks, the acoustics are authentic.

The extensions only appear on the "Simple AGO" page. All other screens and functions are unchanged.

Extended Rotterdam Transept Surround Organ

This is an extension of the complete Sonus Paradisi Rotterdam Transept organ with Six-Channel Surround Sound and Variable Acoustics. It preserves the exact voicing, tremulants, and wind model of the original sample set.
Extensions include:
    ...a strong solo trumpet stop to both the Rugwerk and Borstwerk,
    ...a Quint 2 2/3' on the Hoofdwerk,
    ...a Dulciaan 8' on the Borstwerk,
    ...a Fagot 8' on the Pedal.
The Transept organ set is one of my favorites, but it lacks a strong solo trumpet which is needed for trumpet voluntaries etc.
The solo trumpet (Trompet Grote) is fabricated from the existing Hoofdwerk Trompet with changes to the volume, scaling, and voicing. The new Quint is fabricated from offset and re-tuned samples of the Octave 4 and Octave 2. The Borstwerk Dulciaan is a re-voiced copy of the Rugwerk rank but is under Borstwerk expression and tremulant control. The 8' pedal Fagot is a revoiced copy of the rugwerk Dulciaan. Since these extensions are made from original ranks, the acoustics are authentic.

Zwolle Extended AGO

This is an extended version to the standard Zwolle organ set with an additonal simple screen which has stops arranged according to AGO standards. The AGO simple screen omits the ventels which I find extremely annoying and superfluous for any organ with combination action. The ventils are still there, but only on the other original screens.
One additional stop is added to the Zwolle -- a strong solo Trumpet on the Borstwerk. Although the Zwolle is a large organ in it's original form, it lacks a strong solo reed. This extension allows the organ to play Trumpet voluntaries correctly.

This is a direct addition to the original ODF and retains all the original voicing, wind modeling etc. The only change is the single additional stop and screen. So there are no disadvantages to this version -- the original screens are still there and can still be used if desired.

The installation file is very small because it uses samples from the Sonus Paradisi

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.

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.

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.

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.

Dom Bédos Simple Screen

The Dom Bédos sample set from Sonus Paradisi is a wonderful modern build of a classic French baroque organ. Unfortunately, this sample set was released before the advent of "simple screens" and the photo realistic stop boards are very confusing and hard to read. I have added an extra screen to the organ which is easy to read and use. When this was first programmed, I resisted the temptation to expand the organ. This version therefore exactly duplicates the original Sonus Paradisi version in all ways except for the additional Simple Screen.

The installation file is very small because it only adds three new image files and retains everything else from the Sonus Paradisi version of the Dom Bédos Surround sample set (which must be previously installed):
InstallationFile
The new installation installs as organ number 1258.
Since a new organ number is assigned, the original Dom Bédos Surround installation is not affected in any way. However, it will be completely superfluous after installation of the newer version.
An additional Dom Bédos version has been programmed with an extended stop list -- mostly additional Pedal ranks. The extended version is available above, and I believe it is preferable.

Krzeszow Simple Screen

The Krzeszow sample set from Sonus Paradisi is wonderful three manual baroque organ. Unfortunately, this sample set was released before the advent of "simple screens" and the photo realistic stop boards are very hard to read and manipulate with a touch screen. I have added an extra screen to the organ which is easy to read and use. There is also an additional Oberwerk to Positive coupler, but all other features of the sample set remain unchanged.

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.

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.

The download file is very small because it only uses samples from the Sonus Paradisi

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:
