Frequently Asked Questions
Quick answers to the most common questions about GrandOrgue and Virtual Pipe Organs.
Q: Is GrandOrgue really free to use?
Yes. GrandOrgue is an open-source project licensed under the GPL-3.0. You can download, install, and use it for personal, educational, or even church use without paying any licensing fees.
Q: What kind of MIDI keyboard do I need?
GrandOrgue works with any MIDI-compatible keyboard. This includes digital pianos, stage keyboards, and dedicated MIDI organ consoles. If your keyboard has a USB-MIDI port or a 5-pin MIDI Out, it will work perfectly.
Q: Does GrandOrgue support Hauptwerk sample sets?
GrandOrgue uses its own format (.organ files). While it cannot natively run encrypted Hauptwerk sets, many unencrypted sets can be used if a GrandOrgue ODF (Organ Definition File) is available. Many creators provide versions for both platforms.
Q: Can I use it on a laptop or Raspberry Pi?
Absolutely. GrandOrgue is highly efficient. A modern laptop is more than enough for most organs. There are also specific builds for Linux that run on ARM devices like the Raspberry Pi 4/5 for DIY portable organ projects.
