Just set up cubase

[rui]

I am trying a demo of cubase sx. When I record a guitar track I only hear it playback on the right speaker. Why is this?

......But when I record with my condenser it playsback through both. Why the difference?

Well it sure would help if you included how you have both set up. For starters I'd guess that you are using a mono plug into a stereo line-in input for your guitar. If so, you can get an adapter at Radio Shack to remedy that.
