Kespi_

Pro sample libraries, minus the nerdy part.

Kespi gives your scattered samples a home. It’s a visual sample library designer for composers, simplicity first, with all the features to make your sounds come alive.

What is Kespi?

Where pro-level sample libraries meet composers who’d rather create than code.If you’ve ever recorded a sound you loved, a found object, an odd instrument, something you sampled yourself, and wished you could turn it into a playable, professional library, this is for you. You do it all through a visual interface. No scripting, no manuals, no learning a samplers native coding language.Seasoned Kontakt/Decent Sampler developers are welcome to use it too. But it’s built with composers in mind: the people with the sounds and the ideas, who just want an intuitive way to shape them into something they can actually play.

Drag and play

Drag and drop the controls you want, ADSR, LFO, mic position sliders, and shape your library exactly as you envision it. With Drag and Play, your sample library is ready in minutes.

Function templates

Need something more advanced, like an LFO? Kespi comes with ready-made templates. Drop one in, adapt it to your liking, and play.

Layers

Kespi’s Layers panel keeps your knobs, sliders, and controls organized, just like the design tools you already know. No chaos, just seamless creating.

Website app

No installers, no extra apps, no clutter. Kespi runs 100% in your browser.

Oh, and it has dark mode

We know creatives. We know long hours. Ease the strain on your eyes and go dark.

Now to be fully clear, kespi is by no means trying to replace developers, in a world were people fear getting replaced by digital intelligence. Kespi is here simply to be a tool, and to allow composers into a broader world of sound design.
