Yamaha DX11 patch restore

[ManFromGlass]

A friend was interested in my DX11 so I pulled it out, changed the battery and it booted up. He took a pass but I realized how much fun it is. It does a really nice DX bass that always sat nicely in a mix. It only has single patches in ROM so all the performance patches are gone.

I’ve been searching the internet to find those factory performance patches and a way to restore them. It used to be done with a special cassette player. So far no luck. I can’t find a legacy synth page on Yamaha’s site. I’m going to branch out and start searching general FM synthesis sites and maybe I’ll get lucky. Any suggestions of where to look appreciated.

Sysex, surely. I've got the full factory banks here, I'll message you.
