Download & Installation FAQ
Solutions to the most common setup challenges.
⚠️ No sound after installation?
Check your Audio Settings. Ensure the correct Output Device is selected. On Windows, always use ASIO for the best results. If you don’t have an ASIO sound card, download ASIO4ALL.
⏳ Noticeable delay (Latency)?
Lower your Buffer Size in Audio Settings. A buffer of 128 or 256 samples is ideal. If the sound crackles, slightly increase the buffer until the audio is clear.
🛡️ “Unidentified Developer” warning on Mac?
This is normal for open-source software. Right-click (or Control-click) the GrandOrgue app icon and select Open to bypass the Gatekeeper warning on macOS.
🔄 How to update to a new version?
