jdxi_editor.ui.editors.digital.editor

Digital Synth Editor for the Roland JD-Xi.

This module provides the UI components for editing digital synth parameters on the Roland JD-Xi. The editor supports three partials (voices) with individual parameter control and common parameters that affect all partials.

Classes:

DigitalSynthEditor: Main editor class for digital synth parameters

Handles MIDI communication for parameter changes
Manages UI state for all digital synth controls
Provides preset loading and management
Supports real-time parameter updates via SysEx

Features:

Three independent partial editors
Common parameter controls (portamento, unison, legato, etc.)
Preset management and loading
Real-time MIDI parameter updates
ADSR envelope controls for both amplitude and filter
Oscillator waveform selection
Partial enabling/disabling and selection

Dependencies:

PySide6 for UI components
qtawesome for icons
Custom MIDI handling classes
Digital synth parameter definitions
