drum

This module defines plot widgets for drum envelope visualization: - DrumPitchEnvPlot: Visualizes drum pitch envelope - DrumTVFEnvPlot: Visualizes drum TVF (Time Variant Filter) envelope - DrumTVAEnvPlot: Visualizes drum TVA (Time Variant Amplifier) envelope

All plots digital 5-level, 4-time-segment envelope curves with interactive visualization.

Classes

`DrumPitchEnvPlot`	Plot widget for drum pitch envelope visualization.
`DrumTVFEnvPlot`	Plot widget for drum TVF envelope visualization.
`DrumTVAEnvPlot`	Plot widget for drum TVA envelope visualization.

Functions

`midi_to_pitch_level`(→ float)	Convert MIDI value (1-127, representing -63 to +63) to pitch level (-63.0 to +63.0).
`midi_to_cutoff_level`(→ float)	Convert MIDI value (0-127) to cutoff frequency level (0.0 to 127.0).
`midi_to_time_normalized`(→ float)	Convert MIDI value (0-127) to normalized time (0.0 to max_time seconds).
