Flemish composer and organist. Served the Imperial court from 1566 until his retirement in 1611 as chorister, organist and (from 1603, in succession to Philippe de Monte) court composer. A pupil of Vaet and Monte, he published church music, including some very succinct Masses, and madrigals in a conservative style; his Fuga suavissima for organ is more adventurous in its approach to modulation. He is said to have owned an archicembalo, a keyboard instrument described by Praetorius with 77 keys in four octaves, giving separate keys, for example, for F sharp and G flat.
