JSON Schema for BOSS TSL LiveSet file format Reversed from factory sy-300 preset patches.
Basically, a TSLFile contains LiveSetData, a patchList (which contains patches, which contain 2327 named params - which hold bytes (37 of these params contain arrays of bytes) and chain params (the order of the effects chain))
NB: This is a first stab, generated based on what is in the factory presets. I don't know yet what other optional properties might exist, but just weren't set in any of the default patches. Also, I don't actually have an SY-300; I have a GR-55 and started down this path to see how similar the devices are, and create a parameter/FX map between the two to create a patch converter where appropriate. Feel free to share existing documentation or additions/corrections.
