Instrument
Figure 1: Picture of the organ
The recorded organ was finished by Dieter Ott (Göttingen in Northern Germany) in the year 2003. It has 5 Stops on one manual (56 keys) with attached pedal (30 keys). The stops are labeled with Gedackt 8', Rohrflöte 4', Prinzipal 2', Quinte 1 1/3' and Oktave 1'. Die Tracker is completly mechanical.

This instrument was build for a private person and is currently in private property.
Virtual Organ
Recording
The organ was recorded with a SASS-P MK II stereo boundry layer microphone. Using a Behringer Ultragain Pro preamplifier that also provided the phantomfeeding both channels were sampled using a Terratec DMX 6-fire 24/96-Soundcard with 24 Bit and 96 KHz, using Steinbergs WaveLab Lite Version 2.01a.
Every pipe of every register was recorded individually, at first each tone once and during the second take each tone twice directly after each other, to minimise any probems with the chiff. Additionally for every stop a C major and a D flat major chord was recorded to compare the complete sound. These cords are written down in figure 3.

At last some smaller pieces of organ music were recorded as well as 5 minutes of silence to be able to filter out the background noise of the blower as well as of the environment.
Processing
At first the background noise was removed from all files using the demo version of Cool Edit 2000 Version 1.1. To do this a 3 minute piece of silence was analysed for its frequencies and used as a filter. Surprisingly no mentionable loss in quality of the sound happened, although the blower sounded quite loud to me.
The files were then sampled down to 16 Bit, 44.1 KHz using WaveLab Lite Version 2.01a. They were also cut into pieces using Cool Edit 96 and the best recording of each pipe was selected. Some few pipes had to be borrowed from its neighbors, preferably from another recording, because they gave an unsatisfactory sound. This was only done with tones that were standing out very much, smaller changes in sound in some pipes were left for reasons of authenticity and liveliness of the sound:

After that they were tuned to 440 Hz using the Organ Stop Preparation Tool from Martin Dyde.
Because the organ was in a quite good shape concerning the sound further processings and tonal changes of the recording which Martin Dyde suggests in his recording guide were left out.
At last each individual pipe was trimmed with Zero-X Seamless Looper (with 30 ms space befor the beginning of the pipe sound to allow the chiff, 15 ms of this as fade in to avoid clicks, at the end approx. 120 ms space after the last noticable sound, at the end 30 ms fade out), looped (with at least 80% of the core sound as loop) and supplied with a release marker using Cool Edit 96, at the beginning of the end of the sound.
Together with the .organ file and this documentation the organ was finished.
Technical Requirements
The requirements are mostly set by the program Hauptwerk where version 1.21 is necessary. Specifically for this organ is the need of 313 Mb RAM. All the other requirements are rather at the lower end, because this organ only has 5 stops. Also for the interface only a resolution of 800x600 is necessary.
For optical reasons I suggest to install the font ClerestorySSK which is available for free on the internet, because it is quite similar to the writings on the organ.
Changes
1.0 -> 1.01
- Ott-Orgel.organ: little cosmetic corrections
- jpOtt-Orgel.organ: new, contributes by James Pressler, with twenty new divisionals, to make playing easier
1.01 -> 2.00
- 1.01 for Hauptwerk 1 is still up to date
- Version for Hauptwerk 2
- Most of the work for the Hauptwerk 2-version was thankfully done by Reiner Suikat (http://www.pipeloops.com/), who did this in a very professional manner.
