Sub 37 LFO 2 Rate LED Weirdness

Greetings.

Wondering if anyone else has noticed that the LFO 2 Rate LED gets “choppy” as it dims and brightens (mostly noticeable at slower rates) on the Sub 37 TE. I have no idea if all of them do this, but the one on display did it, and another one I had my hands on (manufactured 6 months before this one) apart also did it.

What is going on? It’s not related to any sort of modulation routing or any other settings – at least that I can find.

Here’s a video to demonstrate (although it is somewhat hard to see the choppiness, but you can definitely see that the LFO 1 Rate LED behaves nicely and 2 is just weird):

Anyone else notice this? Does this only happen when I get near them? :smiling_imp:

I posted this question on gearslutz as well and someone else confirmed that their Sub 37 was doing the same thing, then someone else chimed in with this piece of information:

"yes it’s just the LED. nothing to worry about. basically ran out of full-range CV channels and decided not to ‘waste’ one on a simple LED, so its brightness is set by PWM instead. This can get a little steppy but only visually, nothing to do with the sonics.”
So no need to panic, I guess.

“…This is good news, people…(wink)”

It means that another cool full-range CV feature was able to be added to the Sub 37.
