Hello i have the same problem using Reaper, Cubase.. i recorded a track which is like 2 mins and after exporting is only 16 seconds with no sound at all, i exported it wave.. so waht do i do?
Is it possible that you are exporting a looped or selected region instead of the whole track? In fact, in Reaper, maybe you mean 'render'? Reaper has an 'export midi' function, which I don't think is what you are using.
