Sagan Delay extra LED indication

[Jaga]

Hello everyone!

There's a nice delay circuit by @diablochris which is called Sagan Delay. PCB of the effect is made by carchariaseffects: https://carchariaseffects.com/product-page/dc6fx-sagan-delay-v2-1-pcb/
They have this demo:

The cool thing about this particular build is very nice and useful LED indication: it has LEDs for displaying input signal, every delay stage, LFO and bypass. Just curious anyone has some ideas how it is done? The most interesting this is how these LEDs for each stage are done.

Thanks!

Chris is a regular in these parts; I believe, if you search the forum, you might find some information on the delay and how he did it. This is actually the second generation.

MTK did a really cool job with this, and he did all the heavy lifting with the LED situation. I believe he used a "Sound to Light" circuit from Deadastronaut coming off of pin 15 of each PT2399 and one off of the dry signal too.

Thanks! Looks like that's something I need. Found that link (IC is 386): https://www.aronnelson.com/gallery/main.php/v/chickpea/sound2light2.jpg.html
