Hi there,
I’m not sure if the Liquid foot controller has GCX capabilities, the GCX is on midi channel 16 and is controlled by the following commands.
MIDI CH16, CC80, Data 0 (Loop 1 Off)
MIDI CH16, CC81, Data 0 (Loop 2 Off)
MIDI CH16, CC82, Data 127 (Loop 3 ON)
MIDI CH16, CC83, Data 127 (Loop 4 ON)
MIDI CH16, CC84, Data 0 (Loop 5 Off)
MIDI CH16, CC85, Data 0 (Loop 6 Off)
MIDI CH16, CC86, Data 0 (Loop 7 Off)
MIDI CH16, CC87, Data 0 (Loop 8 Off)
There is a post where John has helped someone out with more info on this.

If it doesn’t have GCX support, I’d say that you are back to where you are with the single GC Pro.
This is only a problem if you wish to have instant access to the loops of the second GCX. They are all able to be switched with presets.
There is a Beta firmware that enables IA (Instant Access) mode, so you have 2 banks of 12 Instant Access switches or if you get a second GC Pro, you can have the Preset GC Pro in Preset mode, the second in IA mode and have 20 Instant Access buttons, plus the other 12 on the second bank. Also, you can have the preset GC Pro in 10 preset mode and the second GC Pro in IA mode and have your 10 presets and 24 IA switches.
