This program sends MIDI requests to the GX100, decodes the received MIDI responses from the GX100, and displays them in the viewer.

MIDI data for the patch is loaded into in the viewer and stays there until you close it.

There is zero possibility that the program can damage the GX100 or any of its patches in any way because it never writes anything to the GX100 memory.

This program was coded in Delphi 12.
