envelope

ADSR Widget for Roland JD-Xi

This widget provides address visual interface for editing ADSR (Attack, Decay, Sustain, Release) envelope parameters. It includes: - Interactive sliders for each ADSR parameter - Visual envelope plot - Real-time parameter updates - MIDI parameter integration via SynthParameter objects

The widget supports both analog and digital synth parameters and provides visual feedback through an animated envelope curve.
