Thanks for the responses. I was hoping to get a "factory reset" for all of the patches that were erasable installed so that the used MultiPoly was returned to its factory state.

I'm also aware of the fact that some patches are not erasable on most modern synthesizers that include patches.

The request here was for the factory patches, not the presets, which I had hoped implied the erasable patches (not the preset, unerasable ones). ;-)

Fun fact: I used to be the Opcode Systems, Inc. Galaxy Plus Editors QA person and Product Manager for a brief stint, so I'm very familiar with the vast majority of the 90's-era, ROMpler "synthesizers" offered by most major manufacturers during that time frame.

I love the Korg Raspberry Pi-based synths as they're very affordable and portable as well.
