The global tuning in cents.
The global key shift in semitones.
The master pan. From -1 (left) to 1 (right). 0 is center.
This uses the cosine panning law, so the perceived loudness remains constant as the pan changes.
The currently enabled MIDI system used by the synthesizer. It changes how the synthesizer behaves, including things such as effects or bank selection.
It can be changed with a System Exclusive reset message. (GM, GM2, GS, XG)
The master volume. From 0 (silent) to 1 (full volume).
Global MIDI Parameters are MIDI-only parameters that affect the entire synthesizer.
They are MIDI Parameters, meaning that they can only be changed via MIDI messages, and not via the API. They get reset via MIDI reset messages.
DEFAULT_GLOBAL_MIDI_PARAMETERS is provided with the library, containing the defaults.
They also have an associated event (GlobalMIDIParameterChangeEvent) and can be locked.
