The app offers a 3D visualization of MIDI data sets, allowing users to listen and view. It supports Standard MIDI File formats 0 and 1, and multiple MIDI ports for playback.
The app provides a grid of pads for playing and manipulating sounds. Users can create custom sounds using the device microphone or iTunes file sharing, and modify them with effects and parameter changes.
The app allows users to play the Ott-Orgel sample set using a MIDI keyboard and pedal connected to an iOS or macOS device. It features a house organ with one manual and an attached pedal with a 16' subbass.
The app sends MIDI signals to MIDI-compatible applications on a Mac. The iPhone or iPod must be on the same WiFi network as the Mac running MIDI software.
