TC Electronics has once again updated the software for their G-Major rackmount guitar processor. The update is available now for free download from TC's web site, and requires a PC running Windows XP or 2000 plus a MIDI interface to install. New features in the version 1.27 release include: In Level, Global Out Level and Preset Out Level mapping - A Mapping Response Curve has been added to the three level parameters in the Mod Menu so you can define your own curve to the "In Level", "Global Out Level" and "Preset Out Level" parameters. This gives control over the behavior when using an Expression pedal to control one or more of these parameters.
