Updates

Two parallel improvements landing today.

• Tutorial Mode: 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
• SEO: added robots.txt, generated sitemap.xml (682 URLs sourced from the modules table and refreshed on demand), per-module <title>/Open-Graph/Twitter-card meta tags, JSON-LD Product structured data, and a canonical URL per page. Search engines and social cards should now actually understand what each module page is about, rather than indexing a single empty SPA shell

Three follow-ups to today's big batch.

• Editor: corner-handle resize on fader and slider hotspots no longer flings them halfway across the panel. The bug was a coordinate-space mismatch between stored bboxes (often in YOLO's 4× upscaled detection space) and the actual displayed image — first touch now silently rescales. Fixes Lifeforms Micro Sequence, Dreadbox Ataxia, and ~30 older modules where fader/slider boxes have been quietly off for a while. 12 new unit tests cover the resize math so this regression can't come back unnoticed
• 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 retailer photo (which would have made hotspot alignment near-impossible) with a flat top-down shot, hotspots remapped

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.

• Voices & oscillators: Synthesis Technology E330 Multimode VCO (FM / wavetable / cloud), Malekko Manther Growl, Befaco Lich (programmable DSP)
• Modulation & LFOs: Synthesis Technology E355 Morphing Dual LFO, Dreadbox Ataxia (dual modulator with ADSR/LFO/function modes), Robaux 3PT (7-mode CV generator), Abstract Data ADE-32 Octocontroller (8-output controller)
• Envelopes & VCAs: Doepfer A-135-2 Quad VCA / Mixer, Doepfer A-143-2 Quad ADSR
• Filters: Frequency Central System X Filter (Roland 100 clone)
• Sequencers & controllers: Pittsburgh Modular Lifeforms Micro Sequence, Shakmat Harlequin's Context (preset/scene programmer), Rossum Mob of Emus (polyfunctional harmonic sextet), Dnipro Modular DOT (3-track polymetric trigger sequencer)
• Drums & voices: Delptronics LDB-2e Little Drum Buddy
• Utilities & I/O: Bastl Noise Square (noise/square VCO), Befaco Instrument Interface (guitar/instrument input), Erica Synths LINK (5-channel format converter)
• New brands on BleepDex: Frequency Central, Robaux, Delptronics, Dnipro Modular, Abstract Data, Pittsburgh Modular (Lifeforms), Rossum Electro-Music expanded, Shakmat (Harlequin's Context), Synthesis Technology expanded, Dreadbox expanded

A wide-ranging batch focused on the small, useful stuff most racks need: passive and buffered mults, line I/O, MIDI, modulation sources, distortion. Plus three module deeper-dive modules and one frontend tweak.

• Multiples & utilities: Doepfer A-180-2 Multiples, Doepfer A-176 CV Source, 2hp Mult, 2hp Buff, 2hp DC, 2hp Switch, Intellijel Buff Mult 1U
• 1U line I/O: Mosaic Line In, Mosaic Line Out
• Sequencing & MIDI: 2hp Euclid, Intellijel µMIDI, Antimatter Audio Brain Seed (step recorder), AniModule TikTok (clock div/mult)
• Modulation & envelopes: ALM Busy Circuits Pip LFO, Endorphin.es Airstreamer (AD/ASR)
• Logic, mixing, distortion: Klavis Logica XT, Befaco Motion MTR, Antimatter Audio Crossfold (wavefolder/crossfader), Neutral Labs Nermal, Ritual Electronics Miasma
• New brands on BleepDex: AniModule, Klavis (Logica XT joins Flexshaper), Mosaic, Neutral Labs, Ritual Electronics
• Mode badges: unlit / “off” LED states now render as a dark grey dot in the Modes panel, so multi-color mode LEDs read correctly even when the default state is unlit (Pip LFO LFO mode, Brain Seed length / quant defaults, etc.)

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
• New: ALM Busy Circuits MCO mk II — eight-engine digital VCO/voice (DigiWave, ToneSum, BC8000, Sylon, Virtana, Oomph, SID Guts, AEIOU), pitch and chord modes, AXON CV expander support
• New: Xaoc Devices Oradea — quadruple voltage-controlled analog resonator with V/oct tracking, gain-compensated extreme Q, per-channel pinging
• New: Xaoc Devices Samarkanda — four-channel mod source
• New: Tiptop Audio Buchla 264t and 242t — Buchla 200-series in Eurorack format
• New: Erica Synths Perkons Voice — modular take on the Perkons drum voice
• New: Befaco STMix 1U — four-channel stereo mixer Hexmix expander (1U Intellijel format)
• New: Endorphin.es Golden Master 1U — 1U companion to the Golden Master mastering processor
• RGB Mode-LEDs now render as actual colored dots in the Modes panel — Endorphin.es Golden Master's Mode LED finally shows Blue / Red / Fuchsia at a glance
