Changelog

Hi everyone! We’ve rolled out a series of updates and fixes to both Suno and Producer integrations. Here's what's new:

1️⃣ Suno Persona API Fixed You can now use the clip_id from any track generated on our platform to create a persona, and then use that persona_id to generate new songs. Fully working again!

2️⃣ New Suno MIDI API We now support a dedicated MIDI API:

https://docs.musicapi.ai/get-midi

Get raw MIDI JSON data for any valid clip_id

Access a processed .mid downloadable URL for playback and analysis

3️⃣ Faster Audio URLs The response speed for audiopipe_url and mp3_url has been improved by 50%+. In most cases, you can now get a streaming link in ~10 seconds, improving your user listening experience dramatically.

3.5️⃣ New audio_weight Parameter (Suno) Useful for cover operations – control how much influence the original audio has over the final result.

4️⃣ Producer Upload Endpoint Added You can now upload a public audio URL (e.g. a song from Suno) to Producer and get a clip_id for remixing. We tested tracks up to ~4 minutes successfully.

5️⃣ Producer Download Endpoint Download audio from Producer by clip_id in MP3 or WAV format – perfect for archiving or re-sharing!

✅ Webhook Support is now LIVE

You can now add webhook_url and webhook_secret to your API requests to automatically receive results when generation completes. Perfect for async pipelines or product integrations.

🎧 FUZZ-2.0 Pro is Here!

Producer API now supports FUZZ-2.0 Pro, our most advanced model to date — delivering audio quality comparable to Suno v5, with improved vocal coherence and scene consistency.

💬 Let us know how you’re using it — excited to see what you build!

We've officially launched support for the Producer AI model (FUZZ‑2.0) as an upgrade to Riffusion.

🔧 What's new:

• ✅ New endpoint: /api/v1/producer

• ✅ Returns 1 song per request (instead of 2)

• ✅ Supports new fields & extended parameters

• ✅ No watermark issue (unlike old Riffusion)

• ✅ Compatible with all standard lyrics, sound, weirdness inputs

The old Riffusion API is still live, but it will no longer be updated and still includes watermarks. We strongly recommend switching to the new Producer API for better audio quality and long-term support.
