Graviton M1 / M2 5.4.0 (Stable) Software Update

New Features:

In comparison to version 5.2.6 Stable:

• Overall UI: Presets, Stomp, actions, messages, and Toggle LEDs are easier to read from a distance. Larger text on sparser layouts. Clearer menus and button descriptions. Snappier, smoother screen response.
• Preset editor: Improved layout so the important buttons are easier to see and reach at a glance.
• Preset editor: Per-preset MIDI Out selection — choose where this preset sends (e.g. preset 1 → TRS 1, preset 2 → TRS 2, plus USB / Bluetooth).
• BPM: Quarter-step BPM (.00 / .25 / .50 / .75) for Live BPM, Song BPM, and preset MIDI Clock.
• Clock LED: Blinks in tempo whenever MIDI Clock is being sent.
• MIDI Clock: Improved timing — smoother generated clock on the 5-pin output for tempo-synced delays.
• Playing Song: Engaged global stomps show On/Off clearly; the base preset keeps the selected look.
• Playing Song: Bottom pill shows current song position in the setlist or song number out of 120 in Song Library mode.
• Playing Song: Touch previous / next song.
• Playing Song: Swap Song in the context menu.
• Playing Setlist: Swap Setlist in the context menu.
• MIDI In: Touch previous / next page control.
• Footswitches: Plug-and-play TRS layouts for 3-button, 2-button, and 1-button footswitches — correct layout without learning.
• Universal Footswitch: Build a custom footswitch layout with 1–10 blocks.
• Touch Lock: Settings → Display can auto-lock the touchscreen after 5 / 10 / 30 seconds (or Off). Footswitches and controllers still work; the back button turns red — double-tap to unlock.
• Channel Filter: Per-port Out and Through channel allowlists for DIN, TRS, USB, and Bluetooth.
• Expression Menu: New menu structure — clearer and easier to navigate.
• Expression Reading: Faster, smoother, more stable expression operation.
• Expression Messages: Send current pedal position after a preset change.
• Controller banks: Each controller follows its own bank by default.
• Bluetooth MIDI: Receives Active Sensing, MIDI Clock, Start, Stop, and Continue again, without Through feedback loops.
• Bluetooth Central: Improved connection stability and reconnecting after Unpair / Scan. Compatibility expanded to many more devices, including ones that require a PIN code (e.g. Roli Lightblock, Boss EV-1-WL, Eventide H90).
• Bluetooth Peripheral: See the list of connected devices.
• USB Host: More reliable device connection — improved enumeration timing and recovery. Works with more devices.
• Settings: New Pedals tab for calibration.
• Backup: Backup loading is now compatible between M1 and M2.
• Safe Mode: After a crash loop, Boot Issue offers Safe Mode (BLE off / USB Device) plus More Options for Import / Export and resets.
• Bank A/B: Banks 11–12 no longer disappear after reboot.
• Setlist: Wrap Back works again when Song +/− hits the end of a setlist.
• Encoder: CC / PC / CV tweaks persist after reboot.
• Counter CC / PC: Live counter values persist after reboot.
• Songs: Song BPM Off now stops the clock when that song is loaded.
• General: Other small fixes and UI polish.
