The Jeux d’orgues project is dedicated to the creation of French pipe organ sample sets, recorded on historic organs.
Connect a MIDI keyboard to your computer and you will be able to play them. The soundbanks are available for Hauptwerk, Soundfont, Vsampler, Kurzweil, Korg Kronos, Gigastudio/Linux Sampler, VST, and even as an iPad and Android app.
