GHX is a program for Windows XP and Windows Vista.It turns a Guitar Hero controller into a real musical instrument, that you can play in a live band, or just play along with your favorite MP3s.You'll need a specific type of Guitar Hero controller; those made for the Wii or Playstation won't do.

The controller made for the XBox (the X-plorer controller) is made to hook up thru a USB port, which is why we can use it on a Windows PC.GHX is an arpeggiator at heart.That means it's designed to play a sequence of notes, not just one.

GHX plays chords (groups of notes that sound good when played together), but it plays the notes in sequence, not all at the same time.So you don't strum or pick the strum bar to make individual notes.Instead, you use the strum bar to both start a sequence of notes, and to keep the beat.

You will find yourself using the strum bar almost like a bass drum, pressing it on the first beat of every measure.To use the GHX properly, you should be familiar with the basic 12-note scale (A,B,C,D,E,F,G, and sharps and flats).You should also be familiar with the difference between major and minor chords (the only two types of chords GHX can play).
