Cakewalk monitoring

[bone]

How can I listen in the left and right side of my headphone when I'm tracking multiple instruments at the same time...insted of panned instruments...say bass in left guitar in right...thats hard to get a good feel laying down trax! I use Cakewalk GTPro, a delta 1010lt card, 8 channel nady preamp, and a Hafler amp with KRK monitors.

Thanx

Why can't you listen to both sides of the headphones? Where are you monitoring from?
