I updated the firmware on my second Ansible to 1.5.1.b01 and LED #4 functions properly. All appears to be great with this new firmware update. Thank you again for making the fix so quickly.
I took a look at the PCB on my first Ansible with the LED issue and see that white LED #4 itself is actually missing. I had previously only used this Ansible with Grid, and often stayed low in octaves, so I hadn’t noticed that it didn’t work. But when I tested with Arc, it was immediately noticeable.
Here’s a closeup photo:
@tehn, should we PM/email about this?
