As usual this version has not been fully tested

Here is the Windows Updater for the GSP1101 beta version C58
* You can't use the old cabinet downloader with vC56-vC58
* Use this cabinet downloader with vC56-vC58
* The stereo IR is fixed in this cabinet downloader 10/5/10

WAH has a new parameter that allows you to link an external CC to the WAH pedal
and auto-engage the WAH on/off (also disengages the pedal CC to any other parameters)
There is now a new parameter to select if the auto-engage toggles the wah on/off
or the wah is turned on/off on a range of the CC controled pedal

The WHAMMY now has the same two parameters as the WAH
The threshold parameter determines where the effect toggles on/off
or the begining CC value where the effect will turn on/off

A threshold value of 127 and the toggle parameter set to 'on' will disable this feature

vC51 - vC58 have a global option (in the main menu) called 'RESET LVLS ON RESTORE'
If you change this option to "YES" before you do a X-Edit restore from version C48
then your levels will be fixed or at least set to normal.
It also fixes the dry levels of the mod effects.
After the restore is done or you restart your unit this option is reset to "NO"

The GSP1101 will now switch to the cabinet that you download to. (really this time)

  Warning! If you interrupt the storing process of a user cabinet you will have to
  do a factory reset and you will lose your user presets. I suggest that you backup your user presets
  before storing user cabinets

To use the cabinet downloader:

  1) download and run the app (link is above)
  2) connect USB
  3) click next until you see the gain/position screen
  4) enter the gain you want, more negative decreases overall cabinet gain
  5) enter the position you want the cabinet to go into (1 to 10)
     If you are auditioning the cabinet then the position doesn't matter
  6) select 'permanent' if you want to keep the cabinet else it will only be temporary
     making a cabinet permanent takes a unit restart
     you can download several cabs at once then set the 'permanent' box once on the last download
  7) click next and wait for it to finish downloading
  8) you can now download another cab without relaunching the app
  9) you may want to try the parameter to enable/disable a low pass filter (xlr only unless wizard 3) in the amp module menu

  Warning! If you interrupt the storing process of a user cabinet you will have to
  do a factory reset and you will lose your user presets. I suggest that you backup your user presets
  before storing user cabinets
