New Features
These are the key functional changes in V1.1.0 and the best places to start after updating.
Tone Files
NAM A2 Native File Support
MG-50Li now supports NAM A2 native files, extending compatibility for model-based tone files.
NUX AUDIO
Cloud Backup and Preset Sharing
NUX AUDIO now supports cloud backup for presets and system parameters. Presets can also be uploaded and shared through the cloud for easier tone management across devices.
Preset Volume
Knob 2 Now Controls Preset Volume
Knob 2 now controls preset volume, with a +12/-12 dB readout added to the preset screen for clearer adjustment.
Delay
TAP / Tempo Supports up to 2000 ms
TAP or Tempo can now set Delay Time up to 2000 ms, equivalent to 30 BPM, making longer and slower delay settings available.
EXP / CTRL
TAP / SCENE applies to S1 / S2 / S3.
EXP/CTRL settings have been optimized so TAP/SCENE settings now apply to S1, S2, and S3 at the same time.
STOMP
New LATCH Control
STOMP mode now supports LATCH control, offering players greater flexibility in footswitch behavior during performance. This makes switching effects on or off feel more familiar and responsive.
Global Settings
Patch Tail On/Off Toggle
Global Settings now includes a Patch Tail On/Off toggle. When disabled, effect tails are completely cut off while switching presets.
USB Audio
USB Audio Streaming to XLR OUT
USB audio can now be streamed to XLR OUT, expanding routing options for recording, monitoring, and live output.
Workflow Improvements
These changes do not require much relearning, but they directly improve daily operation and performance reliability.
Clearer Preset Volume Control
Knob 2 and the on-screen dB readout make it easier to balance preset levels quickly.
Simpler Control Assignment
TAP/SCENE settings now apply across S1/S2/S3, making performance-control setup more efficient.
Refined A/B/C Selection Timing
Preset A/B/C selection timing has been adjusted for a smoother switching feel.
