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. 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. 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. There is also a free version (One Man Band Lite) in the App Store. ## Key features - Real-time auto-accompaniment - Connects to external keyboards via MIDI - Use iOS device as standalone arranger - Supports standard style files (Yamaha PSR, DGX, Tyros) - Customizable button panel - Create custom voices with layering - MIDI file recording ## Recent user reviews (10 of 23) All indexed reviews: https://appshunter.io/ios/app/one-man-band-live/id1372082635/reviews.md ### 4/5 — 自动伴奏有问题 *2025-09-02* 使用中发现节奏不稳 不能与节拍器一直同步 ### 4/5 — Pas mal mais … *2024-07-04, version 1.2* Quelques erreurs ! L’interface demande à être améliorée … ### 1/5 — No style editor! *2024-05-21* Unfortunately, the App is almost useless. It does NOT have a style editor. ### 1/5 — No style editor! *2024-04-27* Unfortunately, the App is almost useless. It does NOT have a style editor. ### 1/5 — ABANDONWARE, DO NOT DOWNLOAD! *2024-04-14, version 1.2* This app has not been updated in five years. I have no way of importing Soundfonts or styles into the app as it does not support iOS and iPadOs’s Files app. Unfortunately I no longer have Windows, so importing styles and Soundfonts via Itunes is out of the question. I sent several emails to the developer regarding this issue, and the developer did not respond to a single one of my emails. Would not recommend. ### 5/5 — Macht echt Spaß *2024-02-23, version 1.2* Finde es auch super ### 3/5 — Why can' you use thus app in background?? *2023-03-02* There are many sample apps for ipad that you can use to play along with this app yet this app can't play in the background. It pretty silli that you have to stop your performance if you de ide to use a different sound from a differen app because this thing can't just keep on playing while you choose a different sound from another app. That's why only 3 stars. ### 5/5 — Great App! Needs a Facelift! *2022-05-28* Have been using the Max version for years and this is definitely the best of the very few arranger app available. As you can import your own styles and use use your own Soundfont, together with the many pages of customisable control buttons, you can do so much with it. The interface, umm… is brand to say the least. As I use the iPhone it is even worse as during performance it is next to impossible to know which button does what! If the developer can update the interface to look more like a real arranger keyboard it will be absolutely amazing! Al least please let us colorise each button for better visibility! Thankyou Jim for creating such an amazing app both in the Max and on the iOS! ### 4/5 — Bien *2022-03-15, version 1.2* Bien mais manque juste le style creator pour être parfait ### 5/5 — Problem fixed *2022-02-09* Do know exactly what it was but I lost accompaniment for a while the start stop button seemed to malfunction but is now working again random bug I guess ## Frequently asked questions about One Man Band Live ### What is One Man Band Live?
