Spatial Panners Guides

These guides match the Package Browser’s Spatial Panners group. The browser lists the individual panner controllers; this page summarizes shared panner workflow patterns.

Panners

The panner controllers are companion interfaces for JSFX. Insert or load the JSFX on a track, then use the matching controller from the package browser or Action List for a larger spatial interface.

General workflow:

  1. Put mono sources on an 8-channel track or bus where the panner expects up to 8 input sources.
  2. Load the matching s3g panner JSFX.
  3. Open the controller.
  4. Use the visual panel, source controls, and automation controls from the controller rather than the raw JSFX fader list.

The Layout Panner is the general option for quad, rings, cube, double-ring, and 24-channel dome layouts. Use it when you want a common speaker arrangement without committing to one SRST-specific array.

Layout Panner and 25ch LBAP Dome Panner include distance-aware controls. Distance rolloff controls level as a source moves beyond the array edge. Distance diffusion broadens the panning focus as distance increases, so an outside-the-array gesture can become both quieter and less point-like. Leave Energy preserve enabled in the LBAP panner when you want equal-power behavior.

The 25-channel dome panners share the RISD SRST dome layout but use different panning ideas:

The 17ch Cube XYZ Panner is an XYZ-native panner. Use smaller spread values when you want a source to focus near a single speaker, and larger distance or offset gestures when you want a source to feel beyond the cube.

The 12ch Dodeca Panner uses an AED-native spherical layout drawn as a dodecahedron. It supports discrete spherical motion with a smaller speaker count.

For automation, use the controller’s automation controls to show, hide, arm, and write relevant lanes. In Trim/Read, the GUI can audition control changes without writing automation. Use write modes when you intentionally want controller motion recorded.

Spatial Score

Spatial Score is a browser-based motion designer for banked 8-source 3OA encoder groups. Use the browser tool to build and preview motion scenes, export JSON, then run Load Spatial Score JSON in REAPER. The primary loader path writes the motion to a focused/touched FX with Azimuth, Elevation, and Distance parameters, such as s3g Ambi Point Encoder, and falls back to X/Y/Z when AED is unavailable. If the score has more point paths than the target exposes, the first matching point paths are used. The alternate loader path creates a 3OA encoder bus with child tracks and writes source automation for s3g 8ch 3OA Object Encoder.

External encoder compatibility depends on what the plugin exposes to REAPER. SPARTA AmbiENC and IEM MultiEncoder can receive azimuth/elevation automation but do not provide distance controls. ICST AmbiEncoder exposes X/Y/Z controls, which the loader handles by deriving XYZ from the score’s AED data.

Spatial Automation Composer

Spatial Automation Composer writes motion as editable automation rather than recording controller movement in realtime. Select a track with a supported s3g AED or XYZ panner, choose a time range, preview the motion, then write the automation lanes.
