 Later designs, as technology progressed, started to encompass more of what could be found in church and other organs and more complex mechanisms, including rollerboards, pedalboards, reed organs (rather than pipes), and eventually electric rather than mechanical actions.Such residence organs were the province of professional house organ makers (who continue to exist even today) in the main, with a notable exception of Toggenburg where (at that time) residence organs were often constructed by amateurs and enthusiasts themselves.Several such purpose-built residence organs survive from centuries past, including Claudio Merulo's organ in the Conservatory of Music in Parma, and the residence organ of Marie Antoinette that is preserved at Versailles.
