Gravity Feed for Surge XT
Turn effect suggestions into Surge XT changes over OSC or automation.
This guide explains how Spatial9 Gravity Feed's effect suggestions can reach Surge XT, the free open-source synthesizer. Status: documented route, no profile yet. Surge XT has a built-in OSC interface for its parameters, which makes it a good target for synth and effect ideas, but Gravity Feed has no Surge XT profile.
At a glance
| Item | Detail |
|---|---|
| Status | Documented route; no Gravity Profile |
| Control routes | Surge XT's OSC input, or host automation |
| Formats | VST3, AU, CLAP, LV2 and standalone (check your platform) |
| Gravity Feed output used | effect_suggestions, not spatial actions |
What Gravity Feed returns for a synth
Each item in effect_suggestions names a track, a kind (reverb, delay, filter, width, dynamics or synth), an intent such as "open the filter slowly across the build" and a reason. Every item has executable: false and carries no parameter value, because no verified effect profile exists yet. Typical ideas:
| Idea | Surge XT controls to look at |
|---|---|
| Brighten across a build | Filter cutoff, filter envelope amount |
| Add width to a pad | Unison voices and detune, the chorus or ensemble effect |
| Push a lead back | Reverb or delay mix in the effect slots |
| Add movement | LFO rate and depth on cutoff or pan |
Connecting over OSC
- Turn on OSC in Surge XT's settings and choose an input port.
- Use Surge XT's OSC specification, available from its menu, for the exact parameter addresses; values are normalized.
- Your adapter turns an accepted idea into OSC messages or automation at the plan's beat times.
FAQ
Will Gravity Feed design synth patches?
No. It suggests changes tied to the arrangement and explains why; you or your adapter decide the exact values.
Why is Surge XT on the list?
It is free, open source and has documented OSC, so it is the easiest synth to connect and test.
