OttOrganApp Version: 7.7
|
OttOrgan is an iOS and macOS application which allows you to play Christian Datzko's Ott-Orgel sample set via a MIDI keyboard. OttOrgan is based on the Napo framework. Please read the Napo documentation and in particular the Napo user manual to learn about its features and limitations.
The app's Gallery view shows a photo of the organ which is part of the sample set package. The background image of the Console view is from the sample set package, as well. The stop button images are borrowed from Thomas W. H. Koppermann's Orgelseiten; they are derived from a photo of the Rückpositiv stops of the Katharinenkirche organ in Hamburg. The stop labels are rendered with the free ClerestorySSK font.
Some years ago, the Ott organ was enhanced by a 16' pedal stop. Unfortunately there are no recordings of the new pipes. To still get equivalent playing options in the app, we have added a Subbaß 16' stop in OttOrgan 6.8, which was derived from the Gedackt 8' by pitch shifting and setting new loop points.
By purchasing this app you support the St. Alexandri Foundation in Einbeck, Germany. 30% of the app's revenue will be donated to the foundation.
This sample set was one of the first publicly available high-quality organ sample sets and is still one of the finest sample sets of small pipe organs that you can get. The sample set files are included in the app with the kind permission of its creator, Christian Datzko, but you can also download the set independently from orgel.datzko.ch if you would like to use it with other software (e.g. GrandOrgue). At orgelbits.de you find some more information about the set (in German), and on contrebombarde.com there are demo recordings done with Hauptwerk.
According to Christian Datzko's documentation, this privately owned house organ was built in 2003 by Dieter Ott (son of Paul Ott) in Göttingen, Germany. It is completely mechanical and has one manual (56 keys) with five ranks and a constantly coupled pedal (30 keys). Somewhat later it was extended by a pedal Subbaß 16'. This is the stops specification:
Name | Notes |
---|---|
Gedackt 8' | C-g3 |
Rohrflöte 4' | C-g3 |
Principal 2 | C-g3 |
Quinte 1 1/3' | C-g3 |
Oktave 1' | C-g3 |
Subbaß 16' | C-g1 |
