Changelog

AI Builder Overhaul. The AI stage plot builder has been completely rewritten. Describe your stage in plain English and it builds itself accurately.

Station-Aware Placement. The AI builder now understands stations as groups of items at a position. "Drum kit upstage center with rug on riser" places everything together as a unit.

Accurate Stage Positions. Upstage, downstage, stage left/right, and new positions like "upstage center" and "downstage center" all place items where you'd expect them.

Meta-Instructions. Say "vocals at all stations" or "monitors everywhere" to copy items to every station in one phrase.

Drum Kit Variants. Specify "drum kit 2 up 2 down" or "1 up 2 down" and the AI places the correct variant. Parentheses like "(2 up 2 down)" work too.

Smarter Synonyms. "Keyboard" and "keys" now place a single keyboard. "Keyboard rig" gives you the 2-tier setup. "Amp modeler", "bass amp", "pedalboard", "person", "people", and dozens more now recognized.

Intelligent Layout. Primary instruments (drums, keys, modelers) go at the front of the station. Amps go behind. Mics go in front of the musician. People auto-sit at drum kits.

Position-Word Safety. Words like "stage" in "stage right" no longer accidentally spawn stage deck items. Filler words like "single" and "large" are stripped cleanly.

Plot Persistence Fix. Plots no longer disappear after signing in. Local plots automatically sync to your cloud account. Autosave no longer silently fails during animated loading.

Kick Drum Logo Fix. Uploading an image to the kick drum head no longer hides the rest of the drum kit.

Locked Item Hover. Position-locked items no longer highlight on mouseover, making them feel properly inert.

Feedback Button. Quick-access feedback button added to the desktop toolbar.

Front/Center Fill. New Audio item — compact horizontal speaker that can be placed on stage or hung from truss.

CDJ. New Instrument with two variants: 1 Deck (single CDJ with jog wheel and screen) and 2 Decks (two CDJs flanking a DJM mixer).

Sub. Renamed from "Subwoofer Stack" and simplified to a single cubic block model.

Acoustic Guitar. Updated to more realistic model.

I/O List Templates. Save and load I/O list templates. Loading a template overwrites the current list but remains fully editable.

I/O List Dropdowns. Type, Stand, and Stage Position columns are now dropdowns with standard options. Column visibility can be toggled, and custom columns can be added.

Mic Defaults. New Account setting — set preferred default mics for common instruments. Defaults auto-fill when instruments are added to the I/O list.

Table Stacking Fix. Fixed issue where placing an item at the center of a table would push the table into the air.

Curtain. New Staging item with wavy fabric geometry — waves increase automatically as the curtain is made wider, with a top pipe/batten.

Ramp. New Staging item — wedge shape that snaps to stage deck edges and automatically adjusts height to match the platform.

Camera. New Video item — broadcast camera on tripod with dolly base, fluid head, lens hood, viewfinder, and shotgun mic.

Half Circle Stage Deck. New stage deck variant — 180° arc shape with independently adjustable width and depth.

Truss Face Mounting. Fixtures can now mount on any of 4 truss faces. Press F to cycle between Bottom, Back, Top, and Front (or Front, Right, Back, Left on vertical truss). Also available as a dropdown in the Inspector.

Line Arrays on Truss. Line arrays can now be attached to truss via the "Attach to Truss" button, just like lighting fixtures.

Improved Truss Workflow. Fixtures attach to truss via the Attach button (no more accidental auto-snap). Dragging a hung fixture slides it along the truss. Detaching drops the fixture to the nearest surface with a fall animation.

Bar Fixture Orientation. Impression Bars and LED Battens now orient vertically when mounted on vertical truss, and mount from their bottom on horizontal truss.

New Drum Kit Configurations (Finally!). Four variants under a new "Drums" parent: 1 up, 1 down (classic 4-piece), 1 up, 2 down, 2 up, 1 down, and 2 up, 2 down — with properly sized and positioned toms for each configuration.

Skateboard. New Misc item with procedural geometry — rounded deck with kicktail ends, trucks, and wheels.

Amp Modeler (Rack). New Instruments item.

Favorites. Heart toggle in the Inspector to favorite any item. Favorites section always visible at the bottom of the Library sidebar for quick access.

ft/m Unit Switching. Toggle between feet and meters in the New Plot dialog, toolbar, schematic/tech view, and PDF export.

Labels. Adjustable width with hover and selection highlighting.

Light fixture truss flip. Fixtures now automatically rotate so their bottom faces the truss when attached (horizontal and vertical).

I/O list bug fix. Adding new items after the first save now correctly merges into the input list instead of showing stale data.

Flyout menu hover fix. Sidebar variant menus no longer disappear unexpectedly.

19 new production objects (148 total). Flute, Clarinet, Oboe, Bassoon, French Horn, Tuba, Gong, Xylophone, Vibraphone, Concert Toms, Concert Bass Drum, Tubular Bells, Trumpet (procedural), Trombone, Saxophone, Marshall Full Stack, PA (on Stand), Podium, and Turntables (renamed from DJ Booth).

Sidebar flyout menus. Instruments reorganized into nested flyout groups — Bass, Guitar, Keys, Horns, Percussion, and Orchestral. Orchestral features nested sub-flyouts for Strings, Horns, Woodwinds, and Percussion.

Lock bug fix. Locked items can now be selected (for unlocking via the inspector) while still preventing move-drag.

Easier clicking on mallet instruments. Marimba, Xylophone, Vibraphone, and Tubular Bells now have filled hit surfaces covering their full footprint.

Custom dimension lines in Tech view. Add, drag, select, and delete measurement lines via the new "+" button. Lines snap to a 0.5ft grid and nodes clamp to the visible frame.

Lightning bolt on power drops. Power drops now display a floating yellow lightning bolt — billboards in 3D, flat icon in Overhead and Tech views.

DI box redesign. DI boxes are larger and now show a "DI" label for easy identification on the plot.

Drop animation on load. Items cascade into place with a satisfying drop animation when plots load — surfaces land first, speed scales with item count.

In-app plan management. View, upgrade, downgrade, or cancel your plan without leaving the app. Billing & invoices link for Stripe portal access.

Performance improvements. Fixed 3 GPU memory leaks, added frustum culling in 2D, render-on-demand, material caching, and eliminated Overhead view lag.

Locked items no longer block pan. Locked items like stage decks no longer highlight or intercept clicks, so Cmd-drag panning works everywhere.

Tech view polish. Sidebar, inspector, and library are now hidden in Tech view. Dark items (mic stands, stairs, laptops) lightened for grayscale visibility. Zoom slider removed.

Venue Directory (Elite). Browse 94 real-world venues — arenas, theaters, clubs, amphitheaters, stadiums, and festival grounds — when creating a new plot. Search by name or city, filter by region and type, and create a plot with accurate stage dimensions in one click.

Wired/Wireless mic stands. All mic stands now render XLR cables from the mic down to a floor coil. A new "Wired" toggle in the Inspector lets you show or hide the cable per stand.

Mic stand improvements. Tall Boom variant flyout now reads Straight / Left / Right. Straight Round Base reoriented to face audience, all-black finish, corrected height, visible grille.

Light / Dark mode. New sun/moon toggle in the bottom-right controls switches between dark and light canvas backgrounds with a smooth animated transition.

Stage Deck skirt. The Skirt checkbox is now available for Stage Decks in the Inspector, previously only for risers.

Auto-seat system. Dragging a Person near a Chair or Stool automatically converts to a seated pose with a live ghost preview. Moving them away reverts to standing.

New items & variants. Chair model. Stage Deck 4x4 and Triangle variants. Mic Stand Boom Left and Right variants. Orchestral instruments: Timpani, Concert Bass Drum, Tubular Bells.

Label formatting. Text labels now support font size (Small / Medium / Large / X-Large), bold, italic, and underline via the inspector panel.

Simplified People. Male and Female variants consolidated into a single gender-neutral Person model.

Bug fixes. I/O List PDF export now shows sequential CH numbers after reorder. GLB models (guitars, keyboards) now selectable after async load. Chairs and stools no longer act as stacking surfaces. Triangle deck surface aligned with frame.

Real-time collaboration. Share your stage plot with collaborators. Editors can make changes that sync live; viewers see updates in real time. Presence avatars show who's online.

View Mode badge. Viewers see a "View Mode" indicator next to the account menu with an "Upgrade to Edit" tooltip.

New lighting models. Moving Head completely rebuilt (Claypaky/Elation style with chunky base, thick yoke, tilted head with lens bezel). Impression Bar replaces Moving Bar/Strip (GLP-style LED trough with 20 cells and end caps).

New instrument models. Standalone Laptop model. Fog machine redesigned to match Chauvet Hurricane 1000. People and table models updated with black surfaces.

Auth & sharing fixes. Share link tokens now persist through email confirmation flow. Demo plot loads after signup instead of blank screen. Fixed auth modal auto-closing after failed sign-in.

Bug fixes. Fixed road cases floating near barricades (stacking heuristic). Fixed truss-mounted fixtures floating above truss line. Fixed bass drum head clipping. Removed number input spin buttons. Snap distance reduced to 0.5ft.

Drum kit rewrite. Completely rebuilt drum kit with realistic Ludwig-style shells, chrome lugs, hoops, spurs, and coated white heads. Kick drum now supports custom logo upload (PNG with transparency).

New 3D models. Pedalboard (flight case with 9 pedals), Hammond B3 organ (dual manuals, drawbars, turned legs, bench), drum throne (chrome tripod), and barricade (vertical bars with flat feet).

Option+drag to duplicate. Hold Option (Alt) while dragging any item to create a copy in place and drag the original to a new position.

I/O List row selection. Click, Shift+click, or Cmd+click to select rows. Drag multiple selected rows to reorder them, or use the Duplicate button to copy them.

More I/O List colors. Three new row colors (orange, pink, cyan) and all color backgrounds are now translucent so labels stay readable.

Riser skirts. Risers now have a "Skirt" checkbox in the inspector that adds black drape panels from the deck edge to the floor.

Rotation buttons. Clockwise and counter-clockwise rotation buttons flanking the rotation field in the inspector for quick 45-degree turns.

Direction labels moved inside stage. Stage direction labels (US/DS/SL/SR) now render inside the stage border so they don't overlap dimension lines.

Backdrop photo upload. Upload a custom photo to any Backdrop / Drape item and it renders directly on the mesh. Compressed and saved with your plot — persists through resizes, page reloads, and cloud saves.

Share links. Generate a view-only link for any plot — anyone with the URL can view it without an account. Share-link visitors see a "View Only" badge and cannot edit or save.

Real-time collaboration. Invite collaborators by email and edit the same plot simultaneously. Changes sync live — no refresh needed.
