One Man Band overview

One Man Band is the software version of the digital music instruments known as arranger keyboards, home keyboards and workstations. It creates auto-accompaniment based on the played chords and it adds auto-harmony to the played melody. Chords and melody can be played in realtime in the Live Window, with or without a connected MIDI keyboard controller or pre-entered in the Sequencer Window. It 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 Internet and the included style editor can be used to tweak existing and create new styles.

What’s new in version

Updated on Apr 10 2020

  • Touch screen control of live performance using Android remote control. In the Live window the JmRemote app provides all the interactions otherwise provided by PC screen and keyboard. Instead of first looking at the screen to find a function and then looking at the keyboard to find the corresponding key, you now look at the tablet to find the function and just touch it directly. If a menu is chosen that changes the functions of all buttons, then the new functions will be displayed in the buttonlabels of the Android app as well as on the PC screen.
  • VSTi support. Use VST instruments, not all of them will work but there is a large collection of freeware synthesizers that sound excelent in One Man Band. Only available in Windows XP, Vista, 8 and 10. Not in Mac Os and Windows 7.
  • Style Editor is completely redesigned. Simple and Advanced View. Event editing in eventslist, pianoroll or staff. Easy instrument editing with knobs.
  • Chords and Lyrics. This new window will play melody and accompaniment from any "plain vanilla" text file with chords and lyrics copied anywhere from the internet. Additionally you can make it a structured song file with stylevariations and export it to a MIDI file.
  • Karaoke enhancements. Support for Unicode (Chinese, Arabic etc. characters). Dynamic background pictures.
  • Sequencer/Arranger window. More intuitive edit window.
