yep you're right.
I just checked my Analogue Systems modules (I only have 3 VCLFO's
though) and they all have flat LEDS's.....interesting.
Maybe doepfer couldn't source any, afterall Doepfer are German and
Analogue Systems are English. What about Analogue Solutions, I have
only 1 filter (MS20) has no LEDS's but do they use flat ones
I wonder if American companies use Flat ones.
