PER|FORMER

The fork started with core sequencing stability work, and this foundation still supports everything built above it.

• Step shifting was stabilized across Note, Logic, Curve, Stochastic, and Arp, including the legacy 64-step crash/reboot path and shift operations inside non-zero subranges.
• Step selection behavior was refined with more consistent shift handling and a shared selection-or-all fallback used across step-edit and generator paths.
• Quick Access step-range editing is now bank-aware: in PAGE-hold overlays for First/Last and Seq First/Seq Last, PREV/NEXT moves 16-step banks and S1..S16 selects inside the active bank.
• Curve tracks were extended with per-step Gate Offset and Gate Length, including edit-page support, overview rendering, Launchpad handling, and simulator bindings.
• Note tie editing became chain-aware: tied steps now keep persistent linkage and share note edits as one pitch group (encoder, MIDI note input, and shortcut note input paths), with clearer tie rendering.
• Scale-selection limits were fixed so the full built-in plus user-scale set is reachable again across Project, Note, Logic, Stochastic, and Arp.
• Voltage Mode is now coherent across Note, Arp, and Stochastic: octave wrapping follows the intended 1.2V span and non-chromatic user scales are preserved on the covered paths instead of forcing semitone/1V/oct fallback.
• Project-scale quantization remap now preserves octave register on Note tracks (Project Scale path with sequence Scale = Default), avoiding octave-collapse when changing Project scale.

Chaos is the boldest Vinx-specific branch so far: intentionally rough, selection-aware, destructive when needed, and built around explicit preview/apply safety.

• Chaos is now framed as an experimental event generator with an explicit preview/apply safety model: a selection-aware multi-layer macro-random engine driven by global Amount and a dedicated target-layers matrix.
• The workflow expands into CHAOS MODE with Vandalize Sequence (local, sequence-level), Wreck Pattern (pattern-wide, multi-track, more destructive), and non-Note Entropy, all with consistent A/B preview and dedicated popups.
• Chaos preview flow is now stricter and deterministic: target/selection/amount edits no longer auto-reroll, CHAOS press stays the only reroll trigger, and APPLY is blocked while no valid preview exists.
• System -> Chaos Defaults now carries separate masks for sequence vandalizing, pattern wrecking, and non-Note entropy unleashed targets.
• Pivot and octave-quantized Span controls were added for Chaos register control, replacing the old fixed note-window assumption with a user-steerable mutation window.
• Performance and memory behavior were tightened through target-step backup only, in-place regeneration, and sequence-scoped storage.

Acid is one of the clearest Vinx-specific expansions of the generator system: more musical, more structured, and layered.

• Acid is now a consolidated Note-track generator with non-destructive preview and a stable Layer/Phrase split.
• Layer mode projects behavior onto a single layer (Gate, Note, or Slide), while Phrase mode writes coordinated Gate + Note + Slide material across the current selection or full pattern.
• Parameter behavior was tightened (density, slide behavior, deterministic target counts) to keep outputs more intentional and repeatable.
• Dedicated visual previews replaced generic generator rendering, and ordering/mapping are aligned across machine pages and Launchpad (Layer → Phrase).

Random evolved from a quick reroll utility into a controlled generator with identity, stability, and compare workflow.

• Random now runs on a non-destructive preview/apply model with A/B, Cancel, Apply, and reroll actions built around predictable state transitions; Variation follows the same per-step keep/replace semantics used in Acid.
• Seed handling moved to stable 32-bit hexadecimal values, and seed edits remain intentional while parameter edits avoid unwanted seed drift.
• Preview rendering is richer and layer-aware (especially on Note tracks), and footer actions stay in context without unexpected page exits.

Launchpad is treated as a first-class performance layer, with coherent defaults, safer generator flows, and stronger routing stability.

• Launchpad remains a core system layer (LP Style / LP Note Style), with defaults aligned to Blue + Circuit while preserving both Classic and Circuit workflows.
• Legacy LP regressions were resolved across note-style rendering, targeting, pattern drawing, fill release, and probability handling.
• LP Generators Mode is track-aware and interaction-consistent. Note tracks use the full map (Random, Acid Layer, Acid Phrase, Vandalize, Wreck, Euclidean, Init Layer, Init Steps), while Curve/Stochastic/Logic/Arp use the subset (Random, Entropy, Euclidean, Init Layer, Init Steps), with aligned A/B, Apply/Cancel/Reset/Undo, reroll behavior, and improved overlay stability, selector alignment, and generator commit behavior.
• Track/scene retarget remains locked during generator selector/pages, track jump to Steps from system pages is supported, and LP input can wake the display.
• Launchpad controller internals were refactored with the P1 structural split (routing, LED drawing, and lock helpers) to reduce coupling and regression risk.

16-step Editing Mode adds a dedicated external-controller workflow for direct per-step note and gate editing on Note tracks. BeatStep Pro template download: PERFORMERstep16_BSP.beatsteppro. On Launch Control XL, use Factory Preset #1.

• The mode provides a dedicated 16 knobs + 16 pads + 2 function buttons control path for Launch Control XL and BeatStep Pro: knobs edit step notes and pads toggle step gates on the current visible 1..16 bank.
• Compatibility is map-driven: any controller can be used if it transmits the map on MIDI channel 9 (CC 13..20 + 29..36 for knobs, notes 41/42/43/44/57/58/59/60/73/74/75/76/89/90/91/92 for gate toggles, CC 106/107 for Prev/Next, Prev+Next for arm/disarm).
• Entry/exit is explicit through armed/disarmed state via controller-side Prev + Next together (LCXL: Track Select < + >, BSP: Ptn 1 + Ptn 2): armed mode forces playback/edit focus to the visible 16-step window, restores the previous loop range on disarm, and keeps longer loops practical through bank-by-bank Prev/Next navigation with the same per-step editing semantics.
• Target scope is the currently selected Note track: knobs are active only when machine layer is Note, while pad gate toggles stay active on that same track across layers.
• Current maintainer-side hardware validation is on Launch Control XL; BeatStep Pro is code-supported and mapping-ready but still pending broader real-hardware validation, and controller concurrency is intentionally constrained to one active external control workflow at a time.

Clock behavior has been adjusted with real hardware compatibility and safer external sync as priorities.

• The default output clock pulse was moved from 1ms to 10ms for broader module compatibility.
• The Swing UI was rescaled to a more natural 0-99% range while preserving original engine timing for backward compatibility.
• Reset behavior was clarified by separating Reset Gate and introducing Reset Pulse as a distinct external clock mode that reacts only to the rising edge, avoiding implicit start on falling edge.
• The default Reset CV behavior is now Off, so Note tracks hold their last CV value on stop unless the project explicitly asks otherwise.
• Track-level gate output behavior can now be switched between Gate and Trigger on Note/Curve/Stochastic/Logic/Arp tracks, with global Trigger Length in System -> User Settings; this is per-track behavior, not per-step trigger editing.

Beyond individual generators, the Vinx line made generator pages more coherent, safer, and easier to perform with in real time.

• The generator ecosystem across track families (Random, Euclidean, Acid Layer/Phrase, Chaos Vandalize/Wreck/Entropy) now follows a more coherent preview/apply safety model shared between machine pages and Launchpad Generators Mode.
• All generators now enter on ORIGINAL; first preview is created only on explicit reroll.
• Generate opens on the current 16-step bank and keeps navigation aligned to the active context.
• The Euclidean generator was reworked with compare behavior, explicit reroll, direct parameter editing, and a strict Beats ≤ Steps constraint.
• Footer and context action layouts were rewritten and normalized across generator pages for faster, less error-prone operation in performance use.
• ResetGen now restores neutral defaults instead of quietly rerolling generator state.
• Init Layer, Init Steps, and Init Seq were separated again with a consistent selection-aware fallback.
• Transport remains responsive inside generator pages so the sequencer stays playable while shaping material.

UI and display work focused on readability, signal clarity during performance, and more intentional visual feedback.

• Generator previews were redesigned around full 64-step views with a clearly visible active 16-step bank and a playback-following playhead.
• Random and Acid rendering was cleaned up with better lane alignment and clearer visual separation.
• Step graphics were refined to make gate offset, length, retrigger, condition, and slide states easier to read at a glance.
• UI load was reduced by lowering refresh to 30 fps and skipping redraws when the frame is unchanged.

System behavior and defaults were refined to make machine-level settings more coherent, safer to manage, and easier to persist.

• System now includes direct save and a simplified settings flow, with an explicit save prompt when leaving System -> Settings after changes (including Chaos Defaults) instead of silently discarding edits.
• Chaos Defaults was returned to the normal machine-settings save path instead of being treated as a separate auto-written case.
• Project file-task flow (Load/Save/Save As) was hardened by serializing requests and delivering results on UI thread, reducing race-prone overlap paths; UI now exposes busy-state feedback while operations are active. This is a strong partial hardening, not yet a full architectural closure.
• SD boot tolerance was hardened for slower cards by extending init tolerance and feeding watchdog during long SD bring-up waits, while keeping runtime watchdog behavior strict during normal operation.
• Menu Wrap was added as an on-by-default preference for cyclic list navigation.
• Screensaver behavior, wake behavior, and the System landing tab were refined for more predictable daily use.
• Memory footprint was improved versus the upstream baseline, with lower SRAM/CCRAM pressure compared to Mebitek 0.3.2.

The simulator side of the fork is now a real part of the ecosystem: useful for development, useful for testing, and documented as such.

• The simulator stack now works as two complementary tools: the browser-based Web Simulator for immediate access and quick checks, and the native Desktop Simulator for deeper MIDI/controller workflows and development work.
• The Desktop Simulator gained configurable DIN/USB MIDI routing via CLI, starts with MIDI disabled by default, and includes built-in status/tracing support (--trace-midi, --trace-dio).
• Launchpad support was improved with model inference and port mirroring to keep controller behavior more predictable in simulator sessions.

Documentation evolves together with the firmware.

• The manual was realigned to current Vinx firmware behavior and kept text-first with technical clarity.
• Online manual search/navigation behavior was improved and aligned with the current documentation structure.
• The Launchpad cheatsheet was fully reworked and synchronized with current firmware workflows.
• Simulator documentation pages were refreshed, and the build guide was expanded with simulator, MIDI, Launchpad, and tracing workflows.
• Ecosystem pages (Forks, Features, and related references) were kept updated as part of the wider site/docs cleanup.

The system is actively used and locally verified, but some areas benefit from broader testing.

• External clock modes (Reset Pulse / Reset Gate) still benefit from real hardware validation.
• Voltage Mode user scales need broader testing across Note / Arp / Stochastic.
• Desktop Simulator USB MIDI has been validated well on macOS / OS X with Launchpad Mini MK3, but not yet across other Launchpads or operating systems.

• Transition from v0.3.2-vinx.* lineage to standalone semantic versioning (v0.x.y) starting from the first standalone Vinx release.
• Previous lineage retained for documentation/reference only.
