jdxi_editor.jdxi.midi.message.sysex.offset

This module defines the offsets for various JD-Xi SysEx messages, including control change, program change, pitch bend, and identity messages. Each offset is represented as an IntEnum to provide a clear and structured way to access the byte positions within the SysEx messages.
