Mapping architecture idea #5

From #2

Lastly, it would be great if someone wanted to help add the MIDX-20 CC-->sysex mappings to this code, but I'd like to do a partial implementation first to set an architectural example.

I ran into http://das.nasophon.de/mididings/ Which seems to have a really versatile set of features to do this.

You can write selectors for the input MIDI messages and use either the SysEx generator to create a single SysEx message out, or use Process to return a list of SysEx events or a generator yielding these. There's also built in possibilities to create separate threads, which could be useful for the I/O of patches on disk.

Keeping the selectors separate from the processing steps would make the bindings very flexible and hackable for people who want custom bindings.

Got ahead of myself and tinkered around with it. It's looking promising.

I made some good progress in being able to map individual values (gain, volume, EQ, etc.) in real time to CC messages from my MIDI controller with this as a framework. If I can mimic the panel preset read/write features as well with it, I'll share what I have.
