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 and Rotterdam 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 and Rotterdam organs have been upgraded to include the exact Sonus Paradisi wind model as well as exact voicing of the original stops. The remaining extended organs were compiled from scratch 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.

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. The ranks not needed by the AGO screen still appear on the original "Simple Jamb" page and need not be loaded in order to miminize memory requirements. This extension includes no extra samples, only a few new graphic images. It requires a prior installation of the full Sonus Paradisi "Rotterdam-Laurenskerk, Hoofdorgel Surround" sample set from Sonus Paradisi, but is otherwise free.

Here is the installation file.
Extended Rotterdam Main Organ Surround InstallationFile
The organ installs as organ number 001247 and will not interfere with the original 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 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.

Extended TranseptSurround Organ InstallationFile
The organ installs as organ number 001255 and will not interfere with the original installation. The original installation will become superfluous since all its features are contained at full quality in the extended version.
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 and an enclosed Positif.
The extra stops are fabricated from original ranks in order to preserve the purity of the acoustic.
The current version of this organ (June 2015) 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.

Here is the screenshot for the page containing the extended organ.

The layout of the extended screen is simple and readable with stops arranged in a predictable manner per AGO recommendations. All the original screens are still available and the organ can be played as if in the original Sonus Paradisi v2.5 version. 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 16.3 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 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.

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. It requires a prior installation of the full Sonus Paradisi Rotterdam-Laurenskerk, Transeptorgel Wet sample set from Sonus Paradisi, but is otherwise free.

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.

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):

The new installation installs as organ number 000755.
Since a new and unique organ number is assigned, the original Demo installation from Sonus Paradisi

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.

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.

The installation file is very small because it only adds a few new image files and uses samples from the Sonus Paradisi.

Since a new organ number is assigned, the original Krzeszow Surround installation is not affected in any way.

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.

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.

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
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:

The new CODM organ installs as organ number 800371 and will not affect the standard Prague Baroque organ installation in any way.
