One Man Band v11 is now available for Linux. One Man Band is an arranger (real-time and sequenced) and style editor for Yamaha Styles. It was already available for Windows and OSX.

Good to know OMB is still alive...

Will there be an iPad version in the future? Now with the iPad Pro it should not be a problem I think.

So many synths on the iPad but yet not a great arranger.

Maybe, but that will take years to develop. There are other options in sight for using a tablet as an arranger. You can run OMB v11 on a windows tablet, it might need some adjustments, but I don't get much feedback from people how actually (trying) to use it that way.

Then a future development might also be a remote app for OMB. It would have the same menu interface as OMB v11 in "Touch screen" mode.

At the moment I am working on a version for the Raspberry Pi, to be used without monitor, computer keyboard or mouse. Just a Pi connected to a piano keyboard or synth will convert it into an arranger. It is operated the same way as OMB v11 in "MIDI Keyboard controller" mode.

Ok thanks for your answer.

tried it on my old ibm r51e 1gig memory, use a casio wk7600 usb into laptop. works great . make sure you go to preferences and set your midi up. i used ubuntu as an operating system. i have the original windows version also.
