Free Beat vs. KOII: Sample Chopping in the Rave Bunker

Sample chopping on the Teenage Engineering KOII finally gets the Free Beat treatment, and it’s about time. Our favourite daily-gear explorer dives into two ways to slice up beats, with a workflow that’s part coffee-fuelled experiment, part practical chaos. Expect hands-on action with patron-submitted drums, a few honest gripes, and a look at what makes the KOII’s sample handling both clever and occasionally clunky. If you want to know whether this box is a street weapon or a fiddly toy, you’ll want to read on—and then watch the video for the full sonic mayhem.

Two Ways to Slice: KOII’s Chopping Arsenal

Free Beat finally takes the KOII’s sample chopping feature for a spin, and it’s not just a quick menu dive. After a stack of previous KOII videos, this is the first time the infamous shift-and-sample combo gets some love. The video opens with a nod to Sunwoo’s tutorial, but don’t expect a dry step-by-step—this is about real-world use, not manual recitation.

There are two main chopping methods on offer. The first is an auto-chop mode, where the KOII tries to detect transients and split your sample accordingly. The second is a more hands-on, live approach: you trigger slices by holding pads as the sample plays. Both methods get a fair shake, and Free Beat’s approach is refreshingly practical—no theory, just immediate results.

It's not just chopping it perfectly into 8. It's actually looking for the transients and attempting to, you know, be a little bit smart…

Patron Beats in the Blender: Chopping in Action

Instead of stock loops, Free Beat loads up drum beats from two patrons—Josh and If Dots—giving the chopping session a personal twist. Each beat gets its own pad and group, setting the stage for a side-by-side demo of both chopping methods. It’s a nice touch that highlights how the KOII handles real, user-generated material, not just pristine demo samples.

The video walks through chopping Josh’s beat with the auto-chop mode, then flips to If Dots’ beat for the manual, live-slice method. Watching Free Beat wrestle with the interface is half the fun—mistakes, tweaks, and all. The process is messy in the best way, showing what actually happens when you try to wrangle samples in a creative session.


KOII’s Sampling Strengths: Groups, Flexibility, and Fun

The way it all works with the groups, I think, is actually really interesting.

What stands out is how the KOII groups chopped samples, making it easy to assign, mute, and layer sounds. Free Beat points out that you can pitch slices, switch to keys mode, and even mash up samples from different tempos for unexpected grooves. The workflow encourages experimentation, and the grouping system is clever—especially for those who like to keep their chaos organised.

There’s a sense that the KOII’s sampling engine is built for quick ideas and happy accidents. Free Beat doesn’t get bogged down in menu-diving; instead, the video shows how easy it is to get from raw sample to playable kit. The device’s intuitive controls and group management are a real asset for anyone who wants to get hands-on without a PhD in menu navigation.

The Chop Struggle: Lag, Tedious Tweaks, and Real Talk

Of course, it’s not all rave and roses. Free Beat calls out the laggy, touchy nature of adjusting chop points, especially when you want precision. The KOII’s lack of a full 16-pad grid and the slightly awkward chop placement can make detailed editing a bit of a toaster-fight. It’s not a dealbreaker, but if you’re a perfectionist, expect some frustration. Still, the honesty is refreshing—no sugar-coating here, just the real workflow warts and all.

It might be a little bit tedious to go in and dial everything in perfectly. So that's kind of a bummer.

Why You Need to Watch: Chops, Chaos, and the KOII in Action

If you want to hear how these chopped beats actually sound, you’ll need to watch the video. Free Beat’s jam session with the KOII is packed with groove experiments, tempo clashes, and a few happy accidents. The real magic is in the demo—seeing and hearing the device in action, with all its quirks and surprises. Trust me, the written word can’t do justice to the KOII’s sample-chopping mayhem. Hit play and let your ears decide if this box is your next sonic street weapon.
