MIDI Identity Request Message Module
This module defines the `IdentityRequestMessage` class, which represents a MIDI Identity Request message.
MIDI Identity Request messages are used to query a device for its identity_request, typically to retrieve information such as its model or manufacturer.
Classes:
- IdentityRequestMessage: Represents a MIDI Identity Request message used to query a device's identity_request.
Features:
- Inherits from the base `Message` class, utilizing SysEx message structure.
- Includes device identification information, such as device ID and fixed SysEx parameters.
- Provides a method for converting the message into a list of bytes for sending via MIDI.
Constants Used:
- START_OF_SYSEX: The start byte for a SysEx message.
- ID_NUMBER, DEVICE, SUB_ID_1, SUB_ID_2: Fixed SysEx identifiers for the identity_request request.
- END_OF_SYSEX: The end byte for a SysEx message.
Usage Example:
>>> identity_msg = IdentityRequestMessage()
>>> identity_msg.to_message_list()
[0xF0, 0x7E, 0x00, 0x01, 0x02, 0xF7]
