GARAGE BAND - "Real Instrument Mode"

Only in "Real Instrument" mode does it allow you to choose reverbs and EQ settings.  If the programs think that "The Track" is a "Loop Track" or "Midi" or something other than a "Real Instrument Track" it will not allow you to add Gate, Reverb, Delay, Gate or Compression.  You must have it in "Real Instrument" mode.
