I noticed yesterday, there was a new firmware for Erae 2.
a couple of important observations
- Erae Lab is not updated, remains at 1.6.3
- v1.1.3 seems to have been withdrawn (and no mention of 1.1.4)
I’d take to mean there was an ‘issue’ so upgrading is likely a very good idea!
pretty extensive change log this time around !
CORRECTION: 1.1.5 change log is identical to 1.1.3
so indeed, seems like a replacement for some reason.
caveat : one line, for both, is “Other miscellaneous fixes and stability improvements”, so this could cover additional bug fixes, that were not in 1.1.3.
but there is no transparency, on what and why 1.1.5 fixed or was necessary 
change log
V.1.1.5
New Features
Expanded Layout Capacity
Layouts now support a much larger number of elements. You can add up to 256 elements per layout (keyboards, drumpads, faders, etc.), enabling more complex and creative setups.
Element Retrigger on Slide
New ability to slide between multiple 1D Fader, Keygrid & Drumpad.
Arpeggiator Quantized Mode
New quantized mode for the arpeggiator:
-
When enabled, the first note is quantized to the MIDI clock grid
-
Ensures arpeggiator patterns start perfectly aligned with the beat
Auto-Load Last Project
The device automatically loads the last used project on startup.
Improved Project Saving
-
Select which project slot to save to (instead of always overwriting the current slot)
-
Current project is marked with " *" in the save menu
-
Currently loaded project slot is highlighted
Element Selection Mode
Hold the Mapping button to enter selection mode:
-
All LEDs dim except the currently selected element
-
Touch an element to select it for editing without triggering it
-
Helps you quickly identify element on the playing surface
Key Fadeout Animation
Keys now fade out gradually after release instead of instantly returning to their inactive state, for a smoother visual experience.
Scale Selection for SoloKey
Added LCD menu to select musical scales directly on SoloKey elements.
CC on Layout Change
New project setting to send MIDI Control Change messages when switching between layouts:
-
When leaving a layout: sends CC with value 0
-
When entering a layout: sends CC with value 127
-
CC number corresponds to layout index: CC 102 for Layout 1, CC 103 for Layout 2, etc.
-
Messages are sent on MIDI channel 16 via USB Device output
-
Useful for triggering scene changes in your DAW or lighting software
Looper Improvement
Quickly double/halve loop length while editing loop length by clicking +/- button — no need to hold the click wheel anymore.
Layout Button Glow on Gesture Activity
Layout buttons (N1-N8) now glow dynamically when playing on non-visible layouts. Glow intensity is proportional to touch pressure and movement speed.
CV Output Support for Footswitches
Footswitch settings now support Control Voltage output configuration.
Bug Fixes
-
Fixed arpeggiator parameters not being saved correctly
-
Fixed multi-finger note tracking for solo keys and keyboard keys
-
Fixed footswitches not responding
-
Fixed duplicate footswitch press/release events
-
- Fixed looper clearing last gesture on other layouts when using layout+Return to clear one or more patterns
-
Other miscellaneous fixes and stability improvements
Performance Improvements
-
Improved MIDI clock timing precision with reduced jitter
-
Improved animations render speed
-
Global performance improvements for smoother operation
Behavior Changes
- External MIDI clock messages now follow configured routing rules instead of automatic propagation
