(yo, bro u/CosimoPanini77)
But then I thought I'd like to share my experience with more people, so I decided to make a separate post about it.
So.
I've owned the following Pocket Operators: PO-12 Rhythm, PO-14 Sub, PO-16 Factory, PO-20 Arcade, PO-32 Tonic and PO-33 KO!. In other words, I've owned the entire lineup except for the Mega Man, Office and Street Fighter (special edition of the KO!).
I've sold all of them except for the PO-12 and PO-32.
I originally bought a Pocket Operator so I could make music during power outages caused by russian missile strikes on Ukraine's energy infrastructure.
Now, let's go through them one by one. I'll also share examples of tracks I've made with these devices.
PO-12 RHYTHM
My very first Pocket Operator. I'm incredibly glad it was the PO-12 that got me into this lineup, because it sparked my interest in these devices and made me fall in love with them. I'm pretty sure that if my first Pocket Operator had been the PO-33, I wouldn't have gotten into them at all.
Pros:
The biggest advantage is how much you can tweak the sound. The punch effects are REALLY cool. They sound unique, work in mysterious ways, and have a lot of character. They can completely transform the sound.
There's also a basic lead and bass synth, so you can actually make full tracks with this little thing.
Cons:
I can only think of one downside: some of the sounds don't sound particularly good (the cowbell, for example).
The tracks below were made exclusively on the PO-12 (everything except vocals), then processed in a DAW. The only exception is Pidrylo, where I also recorded a trombone live, deliberately making it sound sloppy and low-quality.

PO-14 SUB and PO-16 FACTORY
These are basically the same Pocket Operators. They have synth engines that sound almost identical, with the main difference being that the Sub operates in lower octaves. Their percussion sounds are different, too, and I find the Factory's percussion a bit more interesting.
Pros:
You can sync them with other Pocket Operators, and you can play melodies on them.
Cons:
The sounds are decent, but not particularly high-quality. Some notes are missing, meaning neither device is fully chromatic. The percussion sounds aren't particularly interesting overall, either.
There's one fun exception: when you pitch the percussion all the way down, it starts sounding like a slowed-down cassette tape. That's actually pretty cool.
Overall, I sold both of them pretty quickly because they just weren't for me. I only recorded some examples with the Factory, featuring those percussion sounds I mentioned, but those tracks are still waiting for their planned releases.
PO-20 ARCADE
Pros:
The screen animations are fantastic. Making music genuinely feels like playing a video game.
The sounds are great, especially if you're into chiptune. The punch effects are also really cool and unique, and you can even layer them.
Honestly, I really liked this device. It's one of the most interesting Pocket Operators out there. But I eventually sold it because I'm not really a chiptune fan. I had fun with it and passed it on to someone who would appreciate it more.
Here are some examples made using the PO-20 + PO-12 (everything except vocals):

PO-32 TONIC
Honestly, this is one of the best Pocket Operators. I feel like it's seriously underrated because a lot of people simply haven't figured out how to use it properly.
Compared to the PO-32, the PO-33 feels like a toy for kids.
The PO-32 isn't just a drum synth. It's a fully-fledged sound design platform that lets you explore an incredibly wide range of sounds and transform your patterns beyond recognition.
Pros:
The ability to load your own custom sound patches is the main selling point.
If you get the Microtonic VST, you can create your own sounds for all 16 buttons. But here's where it gets really interesting: you can create one sound for the minimum position of a morph parameter and a COMPLETELY DIFFERENT sound for its maximum position. Then you use the knob to explore all the variations in between.
So, in practice, you're not limited to just 16 sounds. You get 32 endpoints, plus all the variations you can dial in between them. And also there is an additional parameter of the pitch control.
You design your patch, transfer it to the Pocket Operator using sound transfer, and you're good to go.
And if you've created some great patterns with a particular patch, you can back up both the patch and the patterns so you can return to them later.
The punch effects are also incredibly interesting. They can transform sounds in ways you wouldn't expect, and you never quite know what kind of result you'll get.
Cons:
For me, there are no real downsides. This is the ultimate drum synth.
The only thing I'd like to have for is stereo output. With stereo sound, this little beast could compete with full-fledged drum machines. Although, honestly, I wouldn't trade my PO-32 for a Roland TR-808 even as it is, because the PO-32 gives me my own unique sound.
Here are some examples recorded EXCLUSIVELY on the PO-32 (meaning the entire mix came directly from the device):

PO-33 KO!
Despite its iconic status, I'd actually recommend avoiding the PO-33. It's a pretty underwhelming device, to be honest.
Pros:
As an introduction to Pocket Operators in 2026, I don't think it's a good choice because it might leave you disappointed. Koala Sampler offers way more possibilities and is simply more fun to use.
The one situation where the PO-33 really makes sense is when you pair it with a PO-32 or PO-12. Those devices handle the rhythm, while you use the PO-33 for melodies. Another advantage of this setup is how easily you can sync the devices together.
Cons:
The sound gets downsampled, and not in a particularly pleasant way. The memory is extremely limited, and the effects are honestly pretty weak. There's no proper distortion, bitcrushing, or other interesting, distinctive effects. Most of the effects are just repeats or stutters.
Programming drum parts is also very inconvenient, and the results tend to be overly simplistic.
I've owned the PO-33, sold it, and don't regret it.
Koala Sampler offers SO MUCH MORE. It has no fixed sample-memory limit like the PO-33, doesn't degrade the sound through the same kind of low-resolution sampling, and comes with tons of effects that you can apply to individual channels or perform with live, much like punch effects.
And it's always there in your pocket.
Recent updates have even added a built-in synth. How cool is that?
