What I would like to do: Record tracks from electric bass, double bass, keyboard, vocals Modify each track and mix down (I would also like to learn how to record live several instruments onto computer and be able to adjust levels but not sure if this is possible with what I have.) Here's the equipment I have: Behringer Xenyx 802 mixer Behringer UCA222 USB soundcard Garageband/Logic Headphones Yamaha digital keyboard has a usb out put as well as a phones/output bass instruments What's the cleanest way to do this with the equipment that I have? Is an active DI box necessary? Where should monitor headphones be coming from and is it possible to adjust monitor headphones to best suit each individual? Thanks in advance for taking the time to help me as I begin to learn recording methods!
