Sonus Paradisi provided me with a 7 day demo of the complete set for evaluation purposes.
There are keys available for anyone, who wants to try complete Sonus Paradisi sets with a time limit.
Franz Xaver Anton Murschhauser (1 July 1663 – 6 January 1738) was a German composer and theorist.
He was born in Saverne, Alsace, but he is first mentioned as a singer and instrumentalist at St Peter's School in Munich, in 1676. He studied music with the Kantor, Siegmund Auer and, from 1683 to his death in 1693, Johann Caspar Kerll. Murchhauser was appointed music director of the Munich Frauenkirche in 1691, where he remained until his death.
He published two collections of organ music in the tradition of the South German school, intended for use with the Catholic liturgy; these consist of short toccatas, fantasies and fugues written using the psalm tones and plainchant melodies.
