Found this info about Delta 44 ..which costs about 250 bucks: (I'll look into this) and the Sonar program!

The Delta 44 is the only computer interface you will need to input and output 4 channels of analog audio from your computer -- all at an
affordable price and at the pinnacle of 24-bit 96kHz fidelity. The Delta 44 system includes a PCI card connected to a sturdy analog break-out box. The break-out box provides four analog audio input and output jacks (1/4" TRS), compatible with balanced or unbalanced, +4dB or -10dB signal levels. Also included is Delta Control Panel software which allows you to control the Delta 44's comprehensive routing, monitoring, and mixing capabilities.
