One way is to monitor through your PreSonus USB 96. The Presonus USB 96 box shows how to connect the laptop and your keyboard audio outputs to the rear of the PreSonus. There will be a rotary knob or switch on the front of the PreSonus USB 96 that blends both audio signals together. The blended audio is then sent to the Presonus headphone jack. The mixer and patch panel are needed in this instance.
