Lo-fi Rain Study
A dusty, rain-soaked lo-fi beat for study streams, calm product videos, and anything that needs a quiet, focused backdrop.
STARTING PROMPT
Reusable prompt
The original English prompt is kept unchanged so you can reproduce the Lo-fi Rain Study example.
A mellow instrumental lo-fi hip hop beat: dusty boom-bap drums, warm Rhodes chords, vinyl crackle, soft rain and distant thunder ambience, upright bass. Calm late-night study mood, 78 BPM, gently swung, no vocals.
How the preview was made
The player on the Lo-fi Rain Study page carries the first 90 seconds of one suno-v4.5 render of this exact prompt, made for the gallery in September 2026 through POST /v1/media/tasks in description mode with instrumental set to true. The square cover art is a separate Nano Banana 2 image made from its own prompt, not from the music prompt.
Make it yours
- 01
Swap the ambience
Replace "soft rain and distant thunder ambience" with the sound the edit needs, for example "passing traffic and a distant train", and keep the level words soft or distant. This clause controls the background texture that sits under the Rhodes chords.
- 02
Say where it is used
Add the use case after the mood, for example "calm bed for a product demo with quiet narration", so the arrangement leaves room in the mid range. A study mood and a narration bed call for different density in the drums.
- 03
Name the instrument
Change "upright bass" to the low end you want, for example "a muted electric bass with long notes", and state whether it walks or holds. The bass line sets how busy the beat feels under speech.
Check before you rely on it
- Keep the prompt in description mode. In our Suno v4.5 tests, eight lines of lyrics produced 45 to 63 seconds, while a description produced about three minutes, close to the length this template lists.
- The progress figure can stay at 0 for the whole job. Poll the status field rather than the figure, or a song that is still being made looks stalled and gets cancelled.
- A signed MP3 link lasts about an hour and the task record 24 hours, so save your own copy as soon as a take is approved. A review that runs past that window has nothing to download.
Run it through the API
Built from the template's model id, prompt and settings. Set OMNIAKEY_API_KEY in your environment first.
curl --fail-with-body https://api.omniakey.com/v1/media/tasks \ -H "Authorization: Bearer $OMNIAKEY_API_KEY" \ -H "Content-Type: application/json" \ -H "Idempotency-Key: $(uuidgen)" \ -d '{ "model": "suno-v4.5", "type": "audio", "operation": "generate", "input": { "prompt": "A mellow instrumental lo-fi hip hop beat: dusty boom-bap drums, warm Rhodes chords, vinyl crackle, soft rain and distant thunder ambience, upright bass. Calm late-night study mood, 78 BPM, gently swung, no vocals." }, "parameters": { "instrumental": false } }' # Then poll the task until its status is succeeded curl --fail-with-body https://api.omniakey.com/v1/media/tasks/<task-id> \ -H "Authorization: Bearer $OMNIAKEY_API_KEY"
Questions
Can I extend this beat into a longer track?
No. On suno-v4.5 only the generate operation is served; extending a song, sending lyrics with no prompt and speech requests all fail, and a failed task gives no file. Write the length you need into the description and generate the whole piece in one pass.
How do I generate this track through the API?
Send POST /v1/media/tasks with model suno-v4.5, the prompt as a description, and instrumental set to true as a request parameter. Poll the task until the state is succeeded, then fetch assets[].url and save the file. Each render counts as one generation, billed at the starting price under Template details.
Is the 90-second player the whole track?
No. The player carries the first 90 seconds of one render made for the gallery in September 2026, and the template lists a duration of about 3 min for the full piece. Run the prompt yourself to get a complete file, then keep your own copy before the link expires.
