The complete Vostok Instruments lineup is now on BleepDex — nine modules, 283 hotspots, deep manual-sourced guides on every one.

• Voice & oscillators: Sena (quad 3340 VCO with per-channel wave modifiers — Fold, Shape, Phase, PWM — plus a four-color analog noise bank), Halo (compact quad LFO with daisy-chained CV and a logic section that turns channel pairs into AND/OR/XOR/MIX outputs)

• Routing & scanning: Path and Trace — Vostok × DivKid 4HP collaborations. Path routes one signal to four outputs with smooth morphing; Trace is its mirror, scanning four inputs to one output. Both feature CV control with attenuator and polarity switching
• Every module includes hotspots for knobs, jacks, slide switches and channel LEDs — no gaps. Path & Trace are attributed to Vostok Instruments in the brand filter for consistent grouping

A five-slide welcome modal auto-shows on first visit and walks new users through what BleepDex does — tap any control, save with stars, search/sort, ModularGrid import. Re-openable any time via the new ? button in the top-right corner.

Two follow-ups to today's big batch.

• Knobula Monumatic: the panel-printed Drive switch now has documentation — two-position filter overdrive (small dot = mild, large dot = strong) injected at the filter input
• Frequency Central System X Filter: replaced the angled product photo with a flat top-down shot so hotspots line up correctly with each control

A meatier batch this round — a few quad VCAs and ADSRs to round out the utility side, plus several voices, filters, modulators and sequencers that have been on the request list for a while.

The big mobile request: tap-friendly modules now actually have tap-friendly controls. Plus ten more headline releases from the past year and two info-panel cleanups.

• Mobile pinch-to-zoom and pan in the module viewer — pinch out anywhere on a panel to enlarge tiny touch targets, drag with one finger to pan when zoomed in, double-tap to fit. Caps at 3× fit so you can't lose your place. Desktop is unchanged
• 10 new modules: Bastl Citadel FX Wizard, Bastl Citadel Wave Bard, Toppobrillo Matrixplexer, Strymon SuperKar+, Entropic Loop Grackle, Schlappi Engineering Boundary Layer, WMD Cosmic Debris, Doepfer A-155-2, Verbos Voltage Multistage 10, and Tiptop Audio Buchla 230t
• New brands on BleepDex: Strymon, Entropic Loop
• Shift overlay now actually shows secondary functions on the controls that have them — the ⇧ toolbar button reveals the printed silver labels (Volume, Filter, Tap Tempo, etc.) inline on each control, not just buried in the modifier-combos list. 54 controls backfilled across the new modules
• Info panel: when a control has only an IO Notes entry and no separate description, the panel now uses the IO Notes content as the description instead of showing “No description available” above a section that already describes the control

Faster favoriting, eight headline modules from the past year, and proper color rendering for multi-mode LEDs.

• Star button on the module viewer — click the ★ next to the module name to add or remove it from your rack without bouncing back to the picker
