Functions

channel_message_from_bytes(data)

Classes

BaseMessageChannel(channel)	Base class for channel messages.
ChannelMessageType(value)	Enum of message types.
MessageAftertouch(channel, note, value)
MessageChannelAftertouch(channel, value)
MessageControlChange(channel, control, value)
MessageNoteOff(channel, note, velocity)

class libmidi.types.messages.channel.BaseMessageChannel(channel: int)

Base class for channel messages.

Since all channel messages have the same structure (at least a channel data + 8 bit data bytes), we can commonize a lot of methods.

__init__(channel: int)

Initialize a channel message.

__str__() → str

Return a string representation of the message.

channel_message_type: ChannelMessageType

copy(**kwargs) → BaseMessageChannel

classmethod from_bytes(data: bytes)

Read a message from bytes.

get_length() → int

get_status_byte()

Return the status byte of the message.

message_type: MessageType = 0

to_bytes()

Return message as bytes.
