What's New

This document records feature updates and bug fixes for the Luxsin X9 controller. Entries are listed in reverse chronological order — the newest release appears first.

v2026.11.03

New Features

  • EQ frequency-response chart: the Y-axis (gain) range is now adjustable. Use the segmented control beside the legend to switch between ±6 / ±12 / ±15 / ±20 dB; your choice is remembered next time.
  • EQ filter type: added "BYPASS" as the first option in the filter-type menu. Selecting it bypasses the band and locks its FREQ / GAIN / Q controls, while the underlying filter values stay unchanged. Requires firmware version 2.0.12.0 (build 2012) or later.
  • Added more interface languages, including Russian and Japanese. These languages apply to the app UI only and are not sent to the device.

v2026.09.22

New Features

  • Added a dedicated "Headphone settings" section on the Audio page, grouping headphone gain and automatic headphone impedance detection.
  • Added maximum headphone volume and headphone startup volume settings. These two settings are shown only on firmware version 2.0.11.0 (build 2011) or later.

v2026.09.01

Bug Fixes

  • Fixed the incorrect firmware version display on the System page.

v2026.08.17

Changes

  • Removed the "Legacy version" entry from the home page. The legacy Web UI is no longer being updated or maintained — please use this new Web UI for the best experience.

v2026.08.06

New Features

  • Added a "What's New" entry on the home page, allowing you to view release notes online.
  • Added Undo support on the EQ page: tap the Undo button to revert your most recent change. It covers band parameter edits (frequency / gain / Q / filter type), slider drag adjustments, preamp and auto-preamp changes, A/B mode copy & switch, and batch edits. Each undo shows a toast describing exactly what was reverted (e.g. "A Band 3 GAIN +2.0 → 0.0").
