For me, part of the point of an arranger is to have physical control buttons available to select intros, sub-styles, fills, outros and so on, i.e., preferably not a touch-screen.

That can be done after a fashion using function keys on a PC keyboard, or on a MIDI controller pad-field, but the ergonomics are less than ideal.

I've occasionally considered putting backupband (Linux only) on something like a Raspberry Pi with a matrix MIDI controller or Novation Launchkey or similar.

I have vArranger, which is quite good, but it uses a USB key and they really don't mix with gigging unless the key is located inside the PC. I managed to break mine within about three weeks and it's now held together with insulating tape.
