I've just bought a brand spanking new computer and want to set it up for home recording. I've installed Cubase SX and I'm using the soundcard which came with the computer. I've got a few problems which i've tried to fix numerous times and are really irritating me:

1) When i plug my guitar or instruments into the line in input to record, i only get sound coming out of the left speaker, but it plays back to both speakers. How do i get the sound to come out of both speakers?

2) I'm getting some latency problems during playback. The sound comes out of the speakers fine, but when i play back what i've recorded, its a bit behind. Also, when i play something, the VU meter doesn't respond until about 1 second later. I've tried switching drivers but then it won't even let me record. It this just my soundcard or is there a way to somehow fix this?

Also while I'm here, does anyone know whether i can connect my Roland Juno D keyboard's midi output to my computer and use it the same way as a normal midi controller keyboard? Is that possible or was that a stupid question?

Thankyou immensly for any help.
