Yes, my buddy Danjel (Intellijel) is using these low-power LEDs in his Euro
versions of my modules. I like to avoid such foolishness myself... :)
But seriously, even at 3mA, if these little wonders are spread around with
impunity, it adds up pretty fast. Five of them would eat up 1% of my power
I recently watched a fellow drive his 200e series Buchla in a live setting a
few weeks ago. I personally found all the blinking lights (and especially
that ridiculous "barber pole" thingie) quite distracting, and I think he did
as well. I've since heard that he's put it up for sale...
At this point, I have 8 LEDs on my entire modular, and I can't say I've
missed not having more. I'm just in the process of building a rather unique
multichannel gate sequencer, however, and that thing is going to be lit up
like a runway...
