Since I found out about the pocket operators series, the one that I always wanted was a sampler, teenage made it so I bought it.
First of all, if you're looking for a sp 404 or a mpc for a fraction of the price, just forget about it, you're going to blow 100 bucks(its monophonic, 40 seconds of sampling time etc...).
This is a great machine, you can record through the built in microphone and then you can cut, pitch and throw a low/high pass filter to the sample. After that you can sequence all the sounds and you can chain sequences together in order to create a song or simply make a 16,32 etc step sequence.
Good: The effects are incredibly fun to use. After creating a sequence you can create a performance by using them.
Bad: the samples are divided in racks and you can't play a 2 samples from the same rack at the same time. For example, if you have in a drum rack a quick drum and a high hat, you can't play both at the same time, the last one added to the sequence will delete the previous sound in that step.
And the sequencer is 4 notes polyphonic, so when 4 samples are playing at the same time, if you add a 5th sample to the sequence in that step, one of the samples will stop playing. That can be a good or a bad thing, sometimes can mess up completely the sequence but other time can help to to create a dynamic sequence through out the time, by adding some samples, others fade away.
Other thing that might be upsetting: You can add samples to the sequence by 16 step mode or live mode. Even though its possible to record live to the sequence, what you play is quantized, so if you try to do something weird keep in mind that the sequencer can mess it up because will quantize what you play, regardless if you want it or not.
Conclusion: Is incredibly fun machine, if you use the limitation in your advantage, you can create really cool things with it.

Teenage Engineering know how to market a product. These things really ARE great but..
Josh Brown, 08.02.2020
Tricky to get used to all the menus, so in that sense has a somewhat steep learning curve. That said, the enjoyment of creating beats out of whatever you've just recorded is pure childlike bliss. I wanted something like this when I was 13 - record whatever noise you like, and it's instantly converted into a 16 note sampler. Beautiful. I did a bit of research and found that for the average consumer (like me) the KO was the best pocket operator to go for, as it offered the greatest flexibility of originality.

For sheer enjoyment level it's 10 out of 10, but as a serious music maker in a studio, I'm not so sure. When there's a DAW sitting in front of you, there's no competition. BUT, for on the road fun, it definitely beats mindlessly scrolling through social media.

Probably worth factoring in one of the TE cases too, unless you like the aesthetic of the pcb.

Oh, the only other thing worth mentioning is the fact that headphones are moving/have moved into Bluetooth only territory. Worth bearing in mind unless you fancy plugging your studio headphones in every time, my old iPhone headphones keep dissapearing...

Simple & Fun
McSharry, 19.12.2019
The K.O. is the most portable synthesizer I've ever owned. While it can be limited when writing whole tracks, it's very easy to start putting together sounds and making nifty little loops.
The sampler feature is phenomenal and it opens up a world of possibility for recording on the go. Unlike the OP-Z, you can sample instantaneously anywhere, any time. And while the library is a bit limited space-wise, the quality is astounding. And editing samples is easy to learn.
The speaker is low quality but as good as you'd expect based on the wafer thin size of the synth. The look of the exposed solder on the board is a nice aesthetic but sometimes I find myself touching the solder behind the knobs and the synth treats it as if I'm moving the knobs. A slight design issue but a minor problem that I wouldn't fault the company on.
I deleted all the factory sounds almost immediately but I believe others may have more use for them as they're quite nice quality samples.
Finally, the live effects are what make this synth, and the rest of the PO series stand out to me. They make playing this instrument a genuinely fun experience.
I'd recommend to anybody interested in sampling to buy this and see what they come up with. It's certainly limited but it's a good learning tool in my opinion, and tonnes of fun for the bus or train.
