Split audio after Korg Gadget

Hey guys,

So I've started my Korg Gadget adventure and done a short album. As old habits tend to not go away that quick, i recorded it like a long track with some silences as split sections between tracks.
My trouble is that Korg Gadget renders the full thing, not allowing me to chose sections (well, not that I've noticed anyway).
So, question is: Does KG has an option to render only a part of the audio? If not, what app should I choose for the splitting that would allow me to avoid the computer?
