A hardware MIDI synth must be played back from beginning to end of song while recording a Stereo Audio Track of the performance with the Line Input chosen as the Recording Source. If using RealDrums and Realtracks along with the MIDI, you must also be able to record the WAV output of the soundcard at the same time. Different sound devices handle this differently, might be labled, "What U Hear" or "Stereo Mix" or something else even more cryptic in the list of Record Inputs (Direct Monitoring is another way of saying this as well...).

That is because the sounds are not stored or created within the host PC, they are external.

So no "Direct Rendering" is possible when using a Hardware Synth.

On the upside, the hardware stuff usually sounds better IMO.
