MIDI ports

Pick which MIDI ports the app uses. The status under each selector tells you whether the port is live.

Device —

Stage Traxx out

?

The port Stage Traxx listens on (Stage Traxx → Settings → MIDI input). Play / Stop / Back / Fwd / Prev / Next song CCs go here, so Stage Traxx can MIDI-learn them. Often the same port as Stage Traxx in if your setup uses a single virtual bus.

—

Stage Traxx in

?

The port Stage Traxx sends on (Stage Traxx → Settings → MIDI output). The lyric playhead follows clock + MTC from here, and the playlist hops to the song matched by the incoming program change.

—

Stage Traxx MIDI-learn

?

Put Stage Traxx into MIDI-learn for the action you want to bind, then click that row's Send. Repeat per action. Stage Traxx's Remote control → Assign actions docs walk through opening the learn screen on the Stage Traxx side.

Setlist

Load a bundled sample or your own setlist .json. The page reloads with the new playlist + FX layout.

?

The ● dot lights up when the FX presets, HIT mapping, or CC labels in localStorage no longer match what the setlist file shipped with — usually because you edited them in the editor's Live tab.

Reloading the page keeps whatever's in localStorage; the marker is purely informational. Use Revert to restore the bundle's values, or Clear all data to start fresh.

Toggle each part of the viewer independently. Compact overrides them all and shows only the buttons column — useful next to Stage Traxx.

Automation source

?

Picks which signal drives HIT and FX changes during a song.

Internal timeline uses cues embedded in the setlist (typically imported from a Stage Traxx `.st4b`). The playhead crosses each cue and Perform writes the corresponding setup change to the device. Needs an external MIDI clock (Stage Traxx) or the local ▶ Play.

Live MIDI CCs reacts to incoming CCs from whatever source you're using — Stage Traxx's live inline CCs, Songbook Pro, a DAW, a hardware controller. Each CC matched against your HIT mapping or an FX preset's CC binding fires immediately. No clock needed; no setlist timeline needed.

You can only pick one at a time — running both can fire the same change twice within a few hundred milliseconds, which is harmless on the device but noisy in the diagnostics. The HIT/FX sidebar buttons (manual taps) work regardless of which source is selected.
