Hi,

I'm not an expert but, you don't need a separate usb-midi conversion box.

When you plug your korg radias with usb, and after launching jack and 
qsynth,

in connexion windows, in audio part, on left colum, you have qsynth 
connected to right colum in system playback, audio is ok.

in alsa part, in left colum, you have your keyboard radias, and in right 
colum, fluidsynth, and you have to connect with the mouse the keyboard 
to fluidsynth.

at this time, you can play music with your keyboard (as i haven't got 
one, i use virtual midi keyboard)

If you have only an old midi keyboard, without usb connexion, you can 
use it under ubuntu studio with an external convertisor midi->usb as 
M-audio Blue

Hope it helps
