MIDI Enhancement: APC Key 25 support (LED feedback)

[doctea]

I'm working on this over in my branch at https://github.com/doctea/r_e_c_u_r/tree/feature_midi_apckey25_feedback. I've got a proof of concept working, with the 3 shader layers being controlled and represented with feedback with lit LEDs.

If anyone's got any ideas on what features they'd like to see mapped or want to beta test it as I go along, please post here or let me know!

This has now turned into this branch https://github.com/doctea/r_e_c_u_r/tree/feature_midi_feedback_plugin which also now has:

• Experimental 'plugin' architecture for adding functionality
• Able to automatically load a custom config file for detected controller
• MIDI feedback implemented as a type of plugin so should be fairly easy to add new controller types
• "Shader Quick Preset Plugin" that can store/recall up to 8 shader presets (layers active, slots selected, parameter values, feedback state) triggerable via MIDI with LED feedback on APC Key 25
• "Shader Loop Record Plugin" that recalls and plays back 8 clips of looping shader parameter changes, with overdub
• 'Sequence' plugin example that handles running sequences of parameter updates or other actions (automate parameters etc, run any python code..) with example of LED feedback on APC Key 25
