Questions and answers
How do I actually use the seed in Suno? Render the seed, then in Suno start a Cover (or Extend) and upload the audio file the app saved. Suno listens to the harmony in that audio and builds its track on your chords. The chord names you typed never go into Suno — only the sound does.
Can I paste in a chord sheet I already have? Usually yes. The app reads each line as a bar and ignores [Section] headings, blank lines and | bar marks, so most plain chord charts drop in almost unchanged. Check the preview's chord count and the "unrecognised" warning to catch anything it couldn't read.
Why is there a MIDI file, and what's the .yams? The MIDI is a convenience for music software — the same progression as editable notes for a DAW. The .yams is the seed's own document — the file you save to keep a seed, and reopen (or double-click) later to re-render or tweak it. Neither is what you upload to Suno — generators can't hear a MIDI, and the .yams is just settings. Upload the audio; the other two are there if you want them.
Which style and format should I pick? When in doubt, Pad and MP3 at 192 kbps. Pad states the harmony clearly without dominating the result, and MP3 keeps the upload small. Change them only when you have a specific reason — a near-silent Marker skeleton, or an uncompressed WAV.
A banner says a new version is available. That's the app telling you a newer release has been published. Use the download link to get it, or dismiss the banner — there's no automatic update, so nothing changes until you choose to install it.
