Kassutronics SLOPE is is a voltage controlled slew limiter and modulation source – it can be an AR envelope, an ADSR, a looping AR stroke LFO, slew limiter – etc. It’s a little bit like half a Make Noise Maths, so I built a couple.
All through hole, straightforward, no issues and not much to say about the build…haven’t done a through hole build in a while, and I definitely find them more laborious.

The wooden panels come with a protective layer that needs to be peeled back before installation.
I like Kassutronics stuff, he often goes into detail about circuit function etc in the documentation. Well worth a look if you’re trying to understand more about the electronics. They’re excellent value for money as well.
