Latent Duality — FBD 13

• ▸Latent Duality is Palme's track for Arc 1: The First Lie — its FBD 13 chart shares the highest documented level in the game, a six-track ceiling.
• ▸Beams sweep the full highway from the opening bars; set your cursor hand's resting position in the first seconds and keep every movement small.
• ▸The crossing-laser sections split your hands: the cursor traces cyan and pink beams while Shift, ASDF and Space keep the keys covered.
• ▸Failing is part of practice: DIVE FAILED ends the run, but the result screen keeps every EXACT and BREAK count for the next retry.

Every frame on this page comes from Kyrosol's Latent Duality chart view (3:25, spoiler-tagged for Arc 1): a straight capture of the playfield with no hand camera. The upload records one complete FBD 13 attempt that ends in a DIVE FAILED — rare documentation of the fail state on this chart.

For a cleared reference run, Hodor1355's EX+ upload (score 99,302,358 as stated in its title) plays the same chart to the end — it is linked here rather than framed because it carries a hand camera. Every figure below deep-links the creator's timestamp.

Latent Duality's catalog entry, straight from the site's song database (community-wiki data, game version 1.0.2c). Levels are documented values from the wiki, not this page's own scoring.

Eight frames, one decision each: where the chart lives on Music Play, what the FORBIDDEN badge promises, how the beams move, and what a failure costs — and teaches.

1. 1

   Find it on Music Play

   Latent Duality belongs to Arc 1: The First Lie, and at version 1.0.2c its FBD chart reads level 13 — a ceiling shared by six tracks in the whole game. Set the difficulty filter to FBD on the MUSIC PLAY screen and Palme's card turns red. If 13 looks steep from the select screen, the same track's ULT 11 chart carries the pattern vocabulary at a friendlier density.

   

2. 2

   Read the FORBIDDEN badge

   The detail screen stamps the pick with a red 13 FORBIDDEN badge — FBD stands for FORBIDDEN, the fourth and hardest tier above MIN, EVO and ULT. This screen is also where the CONNECT partner and the card deck lock in. Treat the badge as a promise: from here on, every lane, beam and hold arrives at the top documented intensity.

   

3. 3

   Claim the lane layout early

   The dive opens with the score at zero — use the first bars to place your hands. The keyboard half runs Shift, A S D F and Space; the mouse field takes everything wide. Kyrosol's run clips an early beam, and that BREAK is the cheap lesson: at FBD 13, nothing waits for you to settle in.

   

4. 4

   Trace the beam pillar

   The mid-chart signature is the full-width pillar: a pink beam that fills the highway and drags your cursor across every lane. Trace it with the smallest movement that keeps contact — wide swings are how notes underneath get dropped. The score keeps counting through the sweep, so hold your line and let the notes come to you.

   

5. 5

   Survive the crossing

   Past the pillar, two lasers — one cyan, one pink — cross paths over the lanes. This is the section that splits your hands: the cursor follows the crossing beams while keys stay covered underneath. The priority rule from every top-end chart applies: a dropped note is a BREAK and a laser path is recoverable, so protect the keys first.

   

6. 6

   Hold the edges late

   The last third pins both edges of the highway with purple and pink beams while centre holds keep the keyboard busy. Nothing new arrives here — it is steps 3 to 5 running at once, and it stays dense to the final bar. Enter the section with gauge to spare, and do not gamble health back for style.

   

7. 7

   When the dive fails

   When the gauge empties, the run stops on a DIVE FAILED banner — Kyrosol's attempt ends this way at 5,223,993, and the frame is proof that failing is a normal part of practicing a level 13 chart. Nothing already earned is lost, and the game offers RETRY from the very next screen.

   

8. 8

   Read the FAILED result screen

   Even a failed dive shows the full result: EXACT, NEAR and BREAK counts, the grade, and the final score beside the FAILED stamp. That makes the failure your cheapest diagnostic — find where the BREAKs cluster and drill that section, not the whole chart. RETRY restarts the same dive on the spot; CONTINUE returns to the menu.
