1766 Karl Joseph Riepp Dreifaltigkeits Organ

Benedictine Abbey of Ottobeuren/Germany, Unter-Allgäu

 

Short Introduction and History

The smaller Holy Ghost organ and the large Holy Trinity organ of the Benedictine Abbey of Ottobeuren/Unterallgäu, founded in 764, are the only surviving instruments built by Karl Joseph Riepp and are both almost completely original. Due to their construction, quality craftsmanship and especially unique architecture and sound, they are an extremely important part of our international organ heritage.

They combine French and Southern German sound ideals and can be regarded as timeless organ treasures. The Rococo Holy Ghost organ is more Southern German orientated while the large Holy Trinity organ has a more typical French character.

Riepp’s organ building style is characterized by numerous warm and full sounding foundation stops, partially lower pitched mixtures, powerful reeds with full resonator lengths, aliquots and cornets with wide scales and beautiful flutes. Exceptional is how well all of the stops blend together.

The Rococo basilica choir has a reverberation time up to 6 seconds.

Recording Technique

The organ was recorded in Okt. 2012/Jan. 2013 with 48 kHz, 24 bit, multi-channel, using the multi-release technique introduced by OrganArt. All stops were recorded with multiple release levels for short, medium and long key attacks for optimal acoustical mapping. Additionally recorded were up to three native tremulant sounds (no simulation!)
The set supports 4-channel (Surround and/or Variable Audio Perspective VAP).

Thanks

Special thanks are due to Abbot Johannes Schaber OSB and titular organist Dr. Josef Miltschitzky for granting permission to record both Riepp organs and organ builder Weber/Leutkirch for his patient work on re-tuning the reed stop and mixtures, as well as smaller ad hoc repairs.

We recommend a professional audio card (e.g. RME-Series) and a studio headphone (e.g. AKG Reference Headphone K701, K712) for optimal sound and room impression.
