    Hello I’ve been trying to add an LED to the Micro Synth so it would respond whenever the filter is active.

    I got this idea after reading in reading in Mark Hammer’s pages. I however cannot seem to find the right opamp to install the LED to. The sketch used in the issue that shows a sketch does not match to my PCB at all neither. (here is a link to that issue, but I think it only covers the vintage unit)

    Any help on how I could install the filter indicator on my version properly?

    Thanks in advance!

    It does only cover the vintage units. That magazine came out years ago.
