But just a year later had to resign from this post following a controversy over his own initiative to create a pedal division and thus modifying the organ without the church authority's approval.
Cajus Schmiedtlein was one of the performers during the inaugural concerts (which, according to a city source, caused a sensation in almost all of Europe) on the newly finished organ (56 stops, 3 manuals + pedal keyboard) at St. Mary's Church on 18 and 19 October 1585.
[12] In 1596 he traveled to Gröningen to play at the inauguration of the organ at the castle, while in 1598[13] he was granted extended leave to go the spa town of Baden to cure an ailment.
[14] Shortly prior to his death, Schmiedtlein wrote a letter to the city council in which he bitterly complained about Siefert's musical skills as well as his personality.
The compositions attributed to Schmiedtlein include 17 Phantasias, one prelude and 24 keyboard arrangements of sacred and secular songs.
