GXT (Guitar XTracktion) function
GXT: Guitar XTracktion is revolutionary technology developed by Korg
that lets you cancel or extract/
emphasize a desired guitar part from an
existing song.
With simple operations you can cancel or extract/
emphasize the guitar
part from your favorite songs so that you can practice or play along on
your guitar. This section explains the various functions of GXT so that
you’ll be able to take full advantage of it.
GXT works by determining the sound’s “stereo position” (panning)
and “frequency band.” This means that it won’t be effective on
monaural songs. Furthermore, other sounds in the same stereo
position and frequency band will be cancelled as well. Also, the
effect may be difficult to notice on some songs depending on how
the guitar part has been mixed.
