Full songs with vocals from style tags and lyrics, in ComfyUI, on a 16 GB Mac. Covers and song extensions too.It runs YuE2 through yue2.cpp on Metal instead of PyTorch, so it fits where the official release wants a 24 GB NVIDIA card. <h2 id="tested-on-an-m1-macbook-air-16-gb.">Tested on an M1 MacBook Air 16 GB.</h2>Included:<ul><li>YuE2 Song: style, lyrics ([Verse], [Chorus], [Bridge]...), seed.</li><li>YuE2 Render: score, melody and audio in one go. Outputs normal ComfyUI AUDIO.</li><li>YuE2 Plan: the ABC score alone, in seconds. Edit it, feed it back, keep the melody.</li><li>YuE2 Transcribe: the melody of a recording. Cover it with your lyrics and style.</li><li>YuE2 Tokenize: a recording as YuE2 codes. Start a new song from a section of it, or re-render it.</li></ul><h3 id="render-times:">Render times:</h3><pre><code> M1 Air 16 GB M5 Pro 48 GB M5 Pro 48 GB

The two node columns compare the chips. Extend on the M5 used a 55 s source, which caps the new song at the source length.Length is the lever: the acoustic stage grows faster than the song.
