What is a MIDI Clip File (.midi2), how is song-level information such as tempo, key, lyrics and names stored in it, and does it carry notation?

A MIDI Clip File (.midi2) is the MIDI 2.0 counterpart of a Type 0 SMF: an 8-byte 'SMF2CLIP' header followed only by Universal MIDI Packet messages; tempo, time/key signatures, names, copyright and lyrics that were SMF meta events are now UMP messages (many as Flex Data text, per producer reading of M2-104). Curator qualifications: Specs read 2026-10-22; no MIDI files written or parsed. Rights hold: MMA/AMEI notice forbids reproduction or transmission in any form without written permission; quote briefly and link, do not redistribute the PDFs or extended text. Flex Data details and the Clip Configuration Header layout from producer reading. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: Specs read 2026-10-22; no MIDI files written or parsed. [component_reuse_restriction] Eligible with rights hold; T14 MIDI 2.0 file interchange.
