Hi,
When weird and unexpected things happen the first line of defence is to perform a factory reset: - Helix LT Reset Options
Helix Floor/LT
Button Combination
Description
2
LED light Fun
3 & 4
Test Mode
5 & 6
Global reset
7 & 8
Reset setlists to factory, Keep IRs
8 & 9
Reset setlists to factory, Clear IRs
9 & 10
Reset setlists to factory, Global reset, Clear IRs
10 & 11
Upgrades existing presets to latest format
11 & 12
Clear current preset
5 & 12
Clear setlists, clear IRs, Return system settings to default
6 & 12
Safe boot mode
To use Reset Options:
Power off the Helix
Hold the desired button combination
Power on the Helix
Release the button combination
Please note: Buttons are numbered from top left to bottom right.
Note: If this doesn’t clear the problem, it maybe advisable to reinstall the Firmware. You didn’t mention what version you have in your LT, but upgrading to the latest version (3.80) helps to fix various known bugs.
Hope this helps/makes sense.
