Opus #1 Pro - The Midi Organ

About Opus #1 Pro - The Midi Organ Android App

Opus #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 ). Opus #1 provides lowest possible latency on your device.

✓ High quality samples for all contained stops

✓ Support for external keyboards and expanders

On devices with 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.

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)
