computer based Synths with midi controllers ?

[Bash_Man]

So our Bassist is using an older Korg O1R/W Synth with a midi pedal.

I wanted to see if there's something similar that can perhaps be loaded on a laptop and used with a Midi Pedal via Midi to USB. Something new technology with better sounds.

Not sure if anyone is using something similar live with their band or even recording.

Thanks
