No External Instrument Tab in AI 5. Help!

I have a yamaha MM8 and I have no problem recording with the HALlion presets via my keyboard. I’m now trying to use the voices from my keyboard instead of the HALion presets, but there is no external instrument tab under the VST connections in the AI 5 version of Cubase. So how do I make this happen? Any help would be much appreciated!!!

Just the same way you make any audio recording happen. MAke an audio connection between keyboard and soundcard, create an audio input in Cubase and record.
