[sdiy-interim] MIDI guitar, the hard way

[Dave Magnuson]

Hi JP,

Your idea sounds good at first glance, but I think you're overlooking a 
problem with guitars and frets.

Using your example,

1st string is held at 12th fret.  Which means the string is touching 11th 
and 12th frets.
2nd string is held at 11th fret.  It's touching 10th and 11th fret

When you scan your fret board the CPU is going to tell you that 1st and 2nd 
strings are touching frets 10, 11 and 12 since everything is a conductor. 
If you're measuring nearest fret to bridge (high note priority) you'll be 
reading 12th fret for both strings
