NOTES FOR FIDDLING WITH TEMPERAMENTS IN NWC.

Unfortunately, if temperaments (eg Kirnberger, Werckmeister, mean-tone tuning, etc) are not 
supported directly by your midi device (some do - so consult your midicard's documentation to 
find out), then you will have to try one of the following three methods. (Also, if you want to
distribute your work to be heard with correct temperament by other people, you will have to 
do this).

Firstly, you must ensure that your midi device supports pitchbend on separate channels. If 
not, give up now or go out and buy a new midi card that does.

There are three ways you can introduce tempering into NWC-produced files.

1) Post-process an exported MIDI file, using Fred Nachbaur's miditemp program (part of the 
Harmonic suite). Note that this will not work correctly with most chords, and thus is only 
suited to pieces whose channels (=staves in NWC) are monophonic. The correct file to play 
will be the output MID file.

2) Post-process an exported MIDI file, using Fred's pianotun program (also part of the 
Harmonic suite).  This program uses a method to circumvent the chord issues of miditemp, 
by splitting chords into separate tracks, and tempering each one. The limitation is then one 
of instrument patches, effectively restricting the user to one instrument. This works well 
for piano, harpsichord and single manual organ pieces. The correct file to play will be the 
output MID file.

3) Insert pitchbend commands for each note in NWC, using a palette of pitchbend commands. 
This has the advantage of avoiding the MIDI-based post-processing, but has the same 
limitation about chords as miditemp. It has the disadvantage of being extremely tedious for 
all but the simplest files.

4) Yeah, I know I said three. The fourth way is to use method 2 to create a split file, and 
then reimport the MIDI file. This will give all notes split into staves depending on which 
note in the octave they are (seven staves if a diatonic piece, twelve otherwise). Then it is 
simply a matter of tempering each staff (NWC doesn't import controllers) at the start of the 
piece. This can also become tedious if you have many changes to make. This can be 
combined with method 3 for multi-instrument pieces.
