Erica Synths EDU DIY Wavefolder Eurorack Module Kit - Manual (Page 19)

In the space between +12 V and -450 mV, the collector voltage rises as the base voltage
drops. And once they meet, they both start dropping together.
So if we use our triangle
wave as an input here, we should get an output with a folded top . To be able to vary 14
the volume of the input, we’ll also set up a simple, temporary attenuator using the 10k
potentiometer from your kit.
Once you’ve set this up, try fiddling with the potentiometer. You should see the shape of
the output signal change as the folding e
ff ect gets more intense.
You can try this chapter’s circuit in a simulator. I’ve already set it up for you right here: https:// 14
