Set-Up

Attempting to Set Up the Following:

CuBase 7

Mixer - Yamaha MG10XU (USB - Computer)
Input 1-4 (Cad-7 Drum Mic’s)

Keyboard - Yamaha E443 (USB - Computer)

Using Yamaha Steinberg USB ASIO Driver

The MIXER - Stereo Outputs (Connected to AUX Stereo Receiver Input (Speakers)

Questions

Should CUBASE be able to detect midi keyboard and direct output to Mixer ? Or do I have to run my keyboard output (Phones) to a mixer input (Channel 5-6,7-8, or 9-10)?

Goal - All Sound Should come from MIXER - Stereo Outputs (Keyboard/MidiVoices/ Drum Mics,)
