[Black] The Pocket operator itself looks very bare, its very playable and you DONT NEED the silicone case, BUT it does improve the feel of the buttons by a bunch, it really does change, and knowing that it can potentially resist a couple more falls really untightens my butt just a bit
This one in black makes it look very sleek.

[25 Keys] This is my fifth Pocket Operator and easily is the best one so far. I wasn't going to spring for the additional Mircotonic software, but I decided to give it a shot and am very pleased. It really opens up your options and it's all very intuitive to use.

[0.12 lb] Great tool.

[25 Keys] You have to actually play with it to appreciate how cool it is and most importantly how great it sounds. This tiny drum machine packs a punch! It is so easy to create complex beats and tweak the sound. It took me 10 minutes to be very comfortable using this device and have tons of fun. It is not a gimmick or toy, it can really create really high quality sounding drum beats, with deep bass and interesting and dynamic instruments. The desktop app with which it shares its engine is a great companion to this device and in my opinion well worth the additional cost. However, even without it you can download sound packs created by the community and the process itself is very cool and to some will bring back the memories of their 80's Atari, Commodore or ZX Spectrum.

[Black] super fun and powerful little device. making beats on the subway is a great way to pass the time

[25 Keys] The CA-X provides a better user experience for your pocket operator. Lights can still be clearly seen through the holes above the buttons. Understand that you have to break off the hang tag to fit it in the case.

[25 Keys] Small and versatile, great functionality

[Black] Teenage Engineering does not disappoint! There is something very relaxing and rewarding about using this tiny but mighty drum machine. It sounds big! The flexibility the ability to load sounds from the Sonic Charge software is huge and expands the possibilities of this device almost infinitely. I wish the LCD graphics were little bit more informative instead of being a tad cryptic, but at the same time it is nice to do everything by muscle memory and ears.

[Black] Not much to say about this. It's study and helps protect my PO-32, just like all the other cases. It's worth getting if you plan on taking your PO on the go.

[0.12 lb] Sonically astounding for the price.

Paired with microtonic it's unstoppable. Buying a second and custom midi adapters just to maximize flexibility of my rig.

Also good to note that the Tonic holds 16 analog drum presets that play across 4 monophonic channels. So each channel also functions as a choke and mute group.

The Microtonic VST has a morph slider that correlates to knob B on the Tonic. You can store one drum sound in the morph sliders first position and one in the second. Repeating this with your own patches allows you to store 32 sounds.

Sounds less fun than it is so I'll say this:

Sonically, I've been blown away and have become a huge Magnus Lidstrm fan.

Functionally, it's fun and easy to get inspiration out. Would love MIDI but it's a $99 TE device.

Value wise, it's so good that I'm buying a second for myself and about 4 for different friends who produce. That means the product was so good that I feel comfortable paying 6x what it costs.
