Consolidated page for Pro-only workflows and advanced extensions.

Maestro Pro extends the standard playback workflows with additional runtime control, advanced loading options, harmonic tools, and script-based MIDI authoring.

This page centralizes all Pro feature families, including MidiSynth-specific extensions, so Pro capabilities are discoverable from a single chapter.
