From the manual... this will over write the factory.glb, it might be an idea to rename it first. The new patches will appear under the 'Tutorial' bank.
Replacing the Factory bank
Be sure to make a backup of the original before overwriting the default factory bank
A more comfortable solution is to replace a part of the factory soundset. The progression
soundset is loaded automatically every time you start Gladiator. You will overwrite
Gladiator's default bank with a new factory bank, where the tutorial category is replaced
with the Progression patches.
Browse to the Progression folder, select & copy the Factory.glb file and paste it to the
following folders
On PC: \Gladiator2\Gladiator2_data\
On Mac: /Library/Audio/Plug-ins/VST/Gladiator2_data/
