[RTcmix-discuss] sample_sco question

[Brad Garton]

Hey gang --

I've almost finished the 'scorefile commands' documentation, even though 
they are probably already outdated.  I figure it's best to get them done 
and then we can change them without too much difficulty into whatever 
modtable() etc. scheme we devise.

While looking at scorefiles in sample_scores/dynamic_insts/minc to figure 
out how some of the new commands work, I ran into this construction in 
"miditest2.sco":

   if (0) {
      freq = makeconnection("midi", min=100, max=2000, dflt=min, lag=50, 
         chan=1, "cntl", 93)
      freq = makedisplay(freq, "freq", "Hz", 2)
   }
   else {
      note = makeconnection("midi", min=0, max=127, dflt=60, lag=10, 
         chan=1, "noteonpitch")
      note = makedisplay(note, "note", "MIDI", 0)
      freq = makeconverter(note, "pchmidi")
   }

How the heck does this logic work?  It's the "if (0)" that I can't quite 
grasp...

I don't have MIDI here at home, so can't try it out.
