jdxi_editor.ui.editors.drum.partial.pitch_env

This module defines the DrumPitchEnvSection class, which provides a PySide6-based user interface for editing drum pitch envelope parameters in the Roland JD-Xi synthesizer. It extends the QWidget base class and integrates MIDI communication for real-time parameter adjustments and preset management.

Key Features:

• Provides a graphical editor for modifying drum pitch envelope parameters, including pitch env depth, pitch env velocity sens, pitch env time1 velocity sens, pitch env time4 velocity sens, pitch env time1, pitch env time2, pitch env time3, pitch env time4, pitch env level0, pitch env level1, pitch env level2, pitch env level3, and pitch env level4.

• Includes a visual envelope plot showing the 5-level, 4-time-segment envelope curve.

Dependencies:

• PySide6 (for UI components and event handling)

• MIDIHelper (for handling MIDI communication)

• PresetHandler (for managing synth presets)

• Various custom enums and helper classes (AnalogParameter, AnalogCommonParameter, etc.)

Usage:

The DrumPitchEnvSection class can be instantiated as part of a larger PySide6 application. It requires a MIDIHelper instance for proper communication with the synthesizer.

Example:

midi_helper = MIDIHelper() editor = DrumPitchEnvSection(midi_helper) editor.show()

Classes
