DelayMessage
============

# Example usage:
# Set delay level
>>> msg = DelayMessage(param=Delay.LEVEL.STATUS, value=100)  # Level 100

# Set reverb send level
>>> msg = DelayMessage(param=Delay.REVERB_SEND.STATUS, value=64)  # Send to reverb

# Set delay parameter 1 to +5000
>>> msg = DelayMessage(
>>>     param=Delay.get_param_offset(1), value=5000  # Will be converted to 37768
>>> )
