One Man Band Lite 4‏+

Change your digital piano or synthesizer into an arranger keyboard with realtime auto-accompaniment. Or use your iOS device on its own as a realtime arranger and be creative while traveling

Connect your iPad, iPhone or iPod to your keyboard instrument with the camera connection kit and an USB AB cable or a MIDI interface cable (depending on what your keyboard uses for MIDI). Then start One Man Band and select the Settings button. Choose the MIDI In and MIDI Out port to your keyboard and press Done. Now select the red Presets button and choose one of the style/voice combinations.

When you play a chord on the leftside of your keyboard instrument, the accompaniment will start to play. You can play the melody on the right side of the keyboard, it will have harmonies and instrument layers depending on the chosen voice. Select different style variations (Main, Fill, Intro, Ending) while you play. Switch to different accompaniment styles and melody voices with the buttons on top. Press Record and set the switch on to record MIDI files.

When you don't have a keyboard instrument (yet) or can't make the connection at the moment, then there are options to use the iPad/iPhone/iPod as an accompaniment instrument on its own. Select the soundfont player at Settings/Ports/MidiOut and use the virtual keyboard to play chords and melody.

The panel with 56 buttons is customisable. You can assign a function, voice, preset, chord or note to each of the buttons (except for the button top left) and create submenus with again 56 buttons each. Create your own voices with harmonies and instrument layering.

One Man Band Lite comes with 10 styles that you can play without restrictions. One Man Band utilises standard style files, compatible with the styles used in Yamaha PSR, DGX and Tyros arranger keyboards. There are thousands of these styles available on the internet. When you copy a zip-file with styles to OMB (download, email, icloud), the styles will be placed in a new style folder with the same name as the zip-file. In the Lite version you can play the 10 included styles, other styles will be paused 15 seconds after 60 seconds of playing. After the pause you can restart the accompaniment by playing a chord. To play the other styles in full you need One Man Band Live, also available in the App Store.
