Gravity Data Feed and sonicLAB SPATAI
How Gravity Data Feed and SPATAI compare and the two ways to use them together.
This guide explains how Spatial9 Gravity Data Feed works with SPATAI, the AI-assisted spatial tool from sonicLAB. Status: works alongside; no direct feed. SPATAI turns a text prompt into motion for up to 64 objects and sends it over OSC or MIDI. It does not document an input for outside position plans, so a Gravity Profile cannot describe it today.

Gravity Data Feed and SPATAI compared
| Gravity Data Feed | SPATAI | |
|---|---|---|
| What it is | Planning service with an API | Plugin and standalone app |
| What you give it | Session metadata: tempo, sections, roles, locks | A text prompt describing motion |
| Knows the song | Sections, roles and beats | The timeline region you play |
| Returns | Three plans with positions, beat-accurate curves and reasons | A live stream of OSC or MIDI positions |
| Numbers made by | Deterministic code; the model only picks ideas | A motion script written from your prompt |
| AI assistants | gravity_feed_plan over MCP and A2A | Its own MCP server |
Ways to use them together
- Side by side. Both can target IEM MultiEncoder. Let Gravity Data Feed move the core of the mix per section and let SPATAI handle textures that need elaborate motion. Never drive the same sound from both.
- Through an AI assistant. Connect an assistant such as Claude Desktop to both MCP servers. The assistant asks Gravity Data Feed for a plan, then describes the movement for chosen tracks to SPATAI.
- Direct feed: not available. SPATAI has no documented input for outside plans, so Gravity Data Feed cannot send a plan into it.
None of these setups has been tested by Spatial9 yet.
What you can do today
Request plans in the playground or over the API, apply them to an encoder such as IEM, and use SPATAI on separate tracks.
FAQ
Is SPATAI a competitor to Gravity Data Feed?
They overlap only a little. Gravity Data Feed plans a whole section from the song's structure; SPATAI performs motion from a prompt. Many sessions can use both.
Will a SPATAI profile come later?
Only if sonicLAB publishes a way to receive outside positions. If that happens, a profile can be written and tested like any other.
