recording

hi,

i am using virtual dj hercules dj console rmx and use the record function on virtual dj to record my mixes.  i find that when i record although i use my microphone and my korg sound pad whilst recording and it all comes through my speakers as normal, when playing back, i only hear the music.  does anyone know how i can record and hear everything on playback?  do i have to add another unit to enable this?  

any advice welcome!!!

many thanks

gary
