I can not get the GI-20 to respond to program change messages over the USB connection. Everything else works fine. I recorded a program change sequence using Logic Pro, but playing that back to the GI-20 did not have any effect on the patch. I did see the MIDI OUT values change in Logic.
For reference, here's what the GI-20 sends when changing a patch:
Program Change message with Patch #
Registered Parameter Number MSB, message #101=127
Registered Parameter Number LSB,  message #100=127
Data Entry MSB message, #6=64
Data Entry LSB message, #38=0

Finally got around to testing if the MIDI input, versus the USB port would respond to program changes..and it does! I ran a MIDI cable from the MIDI out on my audio interface (Echo AudioFire4) to the MIDI In of the GI-20and I can send program changes to the AudioFire4 port and get the GI-20 to change presets.
