I built something similar to manage sysex messages and patch libraries for my digitech guitar modeling workstation with webmidi: https://v0.app/templates/digitech-gnx3000-sysex-tool-GC5LzXA...
My favorite part of this so far has been spanning a range of parameters in seconds that would have taken a much longer time with gdigi and a completely unrealistic amount of time with the built-in knobs.
I own that FPGA now in a way I didn't before.
Speaking of the LXR-02, I just just finished this MIDI/patch editor: https://lxr02.greg.technology/ (free of course) - source code link in the footer
I'd honestly be curious what those “83+ vintage & modern synths” are but you don't even provide a list…
Also, what the hell is a “Hex-to-ASCII Parser”…
I just have sysex librarian installed and pointed to my iCloud directory. It sure works.
Then if you have some of those old newer and more opaque devices too, you would be doing the world a service to reverse engineer their formats with your favorite AI tool and publish them somewhere. For all the conflicting takes that people can harbor about using AI for vibe coding, technical writing, or creativity, the opportunity it provides for documentation/archive enrichment is tremendous.
So many people would be delighted if six months from now we had "SwellJoe's Sysex Wiki" with docs and scripts for a bunch of recovered sysex formats and some prompt/harness/skill tips to help others expand and enrich it further.
