Pick a song with keys notation (sloppak-spec §5.3) and choose Keys Highway 3D from the viz picker (Auto selects it for notation charts). The plugin auto-attaches to your MIDI keyboard; device, channel and transpose are configured from the player for now — this panel holds the graphics controls.
Choose the colour scheme for the falling notes, key glow, lane guides and hit flames. Each option is described in its own label.
Background gradient, floor and lane rails — the same theme names as the guitar highway. Note colours come from the "Note colours" palette above.
Where the camera sits. Classic is the original low rig; Elevated lifts it for a fuller view of the keybed; Overhead looks down the lanes for a sheet-reading feel. Applies live, keeps the auto-pan/zoom that follows your hands.
Raise or lower the camera around the angle above (higher = more top-down). Fine-tunes the base view; the follow-motion stays.
Pull the camera back or push it in (larger = further away, smaller = closer).
Tilt the view up (+) or down (−) without moving the camera — aims higher up the runway or down toward the keys. 0 = neutral.
Dimmer ambience, stronger key light — deeper shading on the keys and gems.
How hard the notes, key glow and sustain consume-flash self-illuminate (0.5 = stock). Pairs with bloom.
The backdrop pulses with the mix (stems analyser when a sloppak is loaded). Off = it animates on time only.
+1 pops on scored presses, a ring pulse every 10-combo, milestone bursts at 25/50/100, and a brief red flicker when a streak breaks.
Soft light-bleed around the hit line, hit flames and consumed sustains. Applies live; turn off to reclaim GPU headroom on weak machines.
A small particle burst on every scored key press, beside the pitch-colored flame.
Tint the sparks by timing — on-time green, early cyan, late amber. Off = always green.
Spark bursts grow with your combo.
Drives the hit-line brightness kick on scored presses. 0 turns it off.
Note-gem solidity and lane-guide strength — lower to see more of the keyboard through the notes.
