To "render" a song played by a hardware MIDI synth such as your keyboard contains, you must connect the Line Output of the keyboard's Audio L and R output to the Line Input on your soundcard and record the MIDI playback performance to Audio stereo wav track from beginning to end. There can be no automatic Render since the engine generating the sound is outside of the PC.

Of course, you must already have the MIDI In and MIDI Out of the keyboard hooked up to the computer properly -- and have the right MIDI input and output ports selected from inside the host program (in BIAB, use the Opts -> MIDI/Audio window to highlight them and hit Okay. Then play back an all MIDI song and ascertain that you can hear your keyboard's synth being used.
