My setup, covering synth bass and also some Mellotron, B3 and ambient pads. I play synth on 4-5 songs in the set these days, either partially (switching to bass halfway through the song) or all the way through.
Synth bass provided by a Bass Station VST, which works pretty well. At the moment I'm only running free VSTs, but I'm not above paying for good ones if I need to.
The brain is a Microsoft Surface Pro 4 (basically a Windows laptop in tablet format), running Cantabile Solo to host VSTs and manage patches, MIDI routing, etc.
The controller is an iRig Keys Pro 37 (one of pretty few decent controllers with three octaves and full-size keys), and the interface is an Arturia Minifuse 1.
