3. Using Ground Link Without a Ground Control
________________________________________________________
With the Ground Link, you can control the GCX Guitar Audio Switcher from
any MIDI foot controller. You can also use the Ground Link as a stand-alone
controller for the GCX. However, because the GCX powers the Ground Link
through the MIDI cable, you must connect the Ground Link directly to the
GCX with a standard MIDI cable. Also, all five pins of the MIDI cable must be
wired. The MIDI OUT of your foot controller, if you are using one, is
connected to the MIDI IN of the Ground Link.
3.1 Single-Channel MIDI Foot Controllers
This section applies to foot controllers that send MIDI Program Change
messages on one MIDI channel only. After connecting your MIDI foot
controller, Ground Link, and GCX as described above, you can control the
GCX by pressing the Ground Link foot buttons to turn GCX loops on and off.
When you change programs with your MIDI foot controller, the Ground Link
responds by changing the GCX loop settings. Program the desired GCX loop
settings as follows:
1. Select a program on your MIDI foot controller.
2. Use the Ground Link buttons to turn GCX loops on or off as desired.
3. Press and hold the STORE button on the Ground Link until the LEDs flash.
Now, when you select that program, the Ground Link and GCX will revert to
the loop settings you have just programmed.
