The current version of MID2PianoCD (1.05) has the ability to do step #6
for you automatically.  It will combine a MIDI file and a corresponding
accompaniment WAV file into a composite WAV file that has the piano
control signal on one channel and the accompaniment on the other
channel, appropriately delayed to sync with the MIDI data.

To use this feature, the WAV file must be in the same directory as the
MIDI file and must have the same filename (other than the extension),
for example:

    sonata.mid
    sonata.wav

The WAV file can be stereo or mono but must have the same sample rate as 
the type of disc you're encoding for in MID2PianoCD- 44.1 KHz for CD, 48 
KHz for DVD.

The MIDI file and WAV file are assumed to start at the same point in
time (they should not be pre-offset from each other).  This makes it 
easy to use exported tracks from a professional sequencer like Sonar.
