It's a little convoluted. I don't know if you are on Windows or Mac, but when you say "Render" I assume you mean record to audio. You're going to need to connect the output of the Ketron to an input of your computer (like the audio in jack on your sound card) and THEN find a way to mix the output of the Ketron with the BIAB sounds (assuming you're using Realtracks?) It'll be easier if it's all MIDI via the Ketron, because it will be one recording source instead of two.

You can probably do a mix with some experimentation using Audacity. I personally find this most usable... https://www.abyssmedia.com/isound7/

A cheap external mixer like a Focusrite Scarlett Solo helps to take both inputs into one output via hardware.
