Sculpt-O-Sound presents Chance-Delay-O-Matic.
I built a gate delay, gate elongater and gate chance thingamabob, all with one arduino nano. There is a demo here:
Gerbers and schematics are at my github.
I think adding the schematics here may make more clear how it works.
Q1 is the output transistor for the gate signals. Using jumper J1 you can choose for a 5V or 10V output signal.
For the built I decided to use 2 PCBs interconnected via CN1.
The IO is relatively striaght forward. Note I’m using high efficiency LEDs which explains the high valued resistors R8, R10 and R11.
I try to get the leds to be equally bright and adapt the resistors once I’ve chosen their color.
In my case I tend to use the following table:
color resistor
===================
1. orange 4k7
2. blue 10k
3. yellow 3k3
4. green 30k
5. red 4k7
Yep, the green leds I use are really bright.
Your mileage may vary.

Hmm, the repository was still private, I hadn’t noticed, but the 18 people who clicked on the link must have found it to be non reachable! If only one of them had made a comment …
Just one …
