Can an adaptation provide a synth specific file import?

[markusschloesser]

K5000 have a file type (ka1 and kaa) which is basically patch/bank minus sysex header. Can an adaptation provide the possibility of importing those?

Good question!

The C++ code can do it, we just need to expose the capability to Python:

	class LegacyLoaderCapability {
	public:
		virtual std::string additionalFileExtensions() = 0;
		virtual bool supportsExtension(std::string const &filename) = 0;
		virtual TPatchVector load(std::string const &filename, std::vector<uint8> const &fileContent) = 0;
	};

This is used by the MKS-80 for example to load the old M80 and MKS80 files.

The current Python code only works on lists of MidiMessages, not necessarily sysex, but it needs to be valid Midi.

So ".ka1" and ".kaa" would go into additionalFileExtensions() = 0;? (or the hopefully upcoming python equivalent)
Strike the "basically", it IS the patch data (which itself is sysex bytes) - header and minus f7

Yes, you could add the additional file extensions, and then the load would get called with the file content basically doing the same what the extactPatchesFromBank... methods do.
