NUX released firmware V1.1.1 for the MG-50Li on July 31, 2026, according to the version listing on the maker's product page¹. The MG-50Li is a multi-effects pedal that NUX describes as its flagship multi-effects processor for guitar and bass¹.

The update adds NAM A2-Lite Native profile support, which NUX says extends compatibility for model-based tone files¹. NUX Audio now supports cloud backup of presets and system parameters, and presets can be uploaded and shared through the cloud¹. Knob 2 now controls preset volume, with a +12/-12 dB readout on the preset screen¹. TAP or Tempo can set delay time up to 2000 ms, which NUX states is equivalent to 30 BPM¹. STOMP mode gains LATCH control, and TAP/SCENE settings now apply to S1, S2 and S3 together¹. USB audio can be streamed to the XLR output, and Global Settings adds a Patch Tail on/off toggle that cuts effect tails when presets are switched¹.

Two factory preset banks, Banks 41 and 42, add six presets: GY Clean LGain, GY Rock, GY RnB Funk, JL-1987x Pack, JL-VH4 Pack and JL-Vib King¹. The firmware also fixes swapped Major/Minor positions in the Harmonist module, WAH model tonal curve and EXP INDEPENDENT W PATCH bugs, abnormal LED display in STOMP mode, and effect-chain display errors under certain conditions¹. NUX advises backing up presets before updating¹.
