Frap Tools SAPÈL Tamed Random Source | In-Depth Tutorial

Take a deep breath and prepare to dive into the realm of true analog modular randomness! If it looks too random, you'll learn how to tame it; if it doesn't look random enough, you'll learn how to make it an actual voltage madness!

Great overview. I have a new student who has this and I wanted to learn more about it to help them out. I love the interrelated design, especially how the fluctuating affects the clock and the >/< density options is smart!

[@FrapTools]

Awesome, thank you! Hope your student will have a good time with Sapèl!

[@btptpt]

Im glad to see this tutorial!

[@FrapTools]

Awesome! We hope that it becomes a useful companion for your randomness taming!

[@Sarahbuildsstepsequencers]

So many amazing possibilities and sounds!

[@FrapTools]

Thank you Sarah! Glad you found it useful!

Excellent video, and the much improved video technique (compared to the overview video from 4 years ago) is very much appreciated.
Now the usefulness (for me) of the slew limiter on Falistri has greatly increased. Thanks for this!

[@FrapTools]

Great to hear! Yes, the overview had a different purpose and style, while this is an actual tutorial. More will come!

[@brianreilly6545]

Great module. Very helpful, thx!

[@FrapTools]

Glad it was helpful!

[@tonymitchell1461]

v clear intro to Sapel that had me patching in no time.

[@FrapTools]

That's awesome to hear, happy patching!

[@antinolfithierry6324]

excellent

[@FrapTools]

Thanks!

[@pablobotelho9477]

is it possible to use an external cv source in the sample and hold circuit? or it only works with the internal noise source?

[@FrapTools]

Hi Pablo! No, SAPÈL's S&H circuits all work on the internal noise sources. However, each works on a separate noise, so that you don't have the same magnitude pattern across all the outputs.

Nice and stiff cables! What are those???

[@FrapTools]

Black Market cables!

You are lovely
