So the title says it all.... I am especially unsure if I should get the WL Random or just get a white noise generator with a sample and hold module. If this is the case I would need to get a clock or gate generator of some sort which I know nothing about. Maybe instead I should get a Pico trigger and seq?
Any help, opinions or tips would be very welcomed!

Here is the rack, I have no idea how to post it here:
