Tuning Map

[kunitoki]

This pull request introduces a new TuningMap class to the audio MIDI module, enabling flexible mapping of MIDI note numbers to frequencies using arbitrary scales and key maps, with support for loading Scala .scl and .kbm files. The change also integrates this new class into the audio basics module and its test suite.

New MIDI Tuning Features:

• Added the TuningMap class (midi/yup_TuningMap.h), which allows mapping MIDI notes to frequencies under custom scales and key maps, with methods for loading Scala .scl and .kbm files, querying note activity, and ensuring thread-safe, atomic updates. [1] [2]

Integration and Build Updates:

• Included the new yup_TuningMap.h header in the main audio basics header (yup_audio_basics.h) and implementation file (yup_audio_basics.cpp), making the class available throughout the module. [1] [2]
• Added the yup_TuningMap.cpp implementation to the test suite build (tests/yup_audio_basics.cpp) to facilitate unit testing of the new functionality.
