Struct gba_hal::data::DutyLenEnvelope

#[repr(transparent)]
pub struct DutyLenEnvelope(_);

Combines the main pulse voice effects into a single setting.

• 0-5 (wo): Sound length, (64-n)/256 seconds
• 6-7: Pulse Duty
• 8-10: Time per envelope step: x/64 sec, or 0 for no envelope.
• 11: If the envelope is increasing or decreasing.
• 12-15: Initial envelope volume (0 = no sound)
