jdxi_editor.midi.program.helper

This module defines the PresetHandler class, which extends PresetLoader to manage preset selection and navigation for a MIDI-enabled synthesizer.

Classes:

  • PresetHandler: Handles preset loading, switching, and signaling for UI updates.

Dependencies:

  • PySide6.QtCore (Signal, QObject) for event-driven UI interaction.

  • jdxi_manager.midi.data.presets.type.PresetType for managing preset types.

  • jdxi_manager.midi.preset.loader.PresetLoader as the base class for preset loading.

Functionality:

  • Loads presets via MIDI.

  • Emits signals when a preset changes (preset_changed).

  • Supports navigation through available presets (next_tone, previous_tone).

  • Retrieves current preset details (get_current_preset).

Usage:

This class is typically used within a larger MIDI control application to handle preset changes and communicate them to the UI and MIDI engine.
