DescriptionOpus #1 Pro uses samples from a real church organ (coming from http://www.jeuxdorgues.com) for a great realistic sound.
You can download demo recordings and a trial version from http://www.refined-apps.com/opus-1
We also offer other music apps, including a version of the full Stiehr Mockers organ (the "Ultimate" version). For details, see refined-apps.com.

-- Highlights ----------
✓ Low latency audio
Low latency audio is a weak spot of Android (see http://code.google.com/p/android/issues/detail?id=3434). On the Galaxy Nexus, low latency audio is finally possible. Opus #1 is one of the very few apps already supporting this! On other devices, Opus #1 provides lowest possible latency.
✓ High quality samples for all contained stops
✓ Support for external keyboards and expanders
On devices with Android >= 3.1 and USB host support (e.g. Galaxy Nexus, Nexus 7, Acer A500, Asus TF101, ...) you can connect an external keyboard or midi expander. You can play Opus #1 from your external keyboard, organ midi console or play an external sound generator from Opus #1.
✓ Midi file player included
The included midi player works with any standard midi file stored on your android device. You can output the midi events via Midi/USB (if your device supports it; see above)
