Wunderkammer WoO.1: Is This New Portable Sampler a Chompi Killer?
2,7 / 5,0 | 
With sampling, looping, and even a built-in game, will the new Wunderkammer WoO.1 be the next Chompi?
Wunderkammer WoO.1
If you had told me even five years ago that “cute portable sampler” would be a hot niche in the musical instrument market, I would have suggested that you’re spending too much time around bath salts. But here we are in 2025 with all sorts of fun samplers on the market – and a new one ready to take on all challengers. Called Wunderkammer WoO.1, it looks to be a fun and agile little instrument with a lot of the mod cons you expect – but a few that you might miss.
Seven Modes
WoO.1 is currently a prototype, with a Kickstarter getting ready to launch on 19 August. The portable white instrument, which seems to take design inspiration from Teenage Engineering, the Chompi, and even Yamaha’s SEQTRAK, offers seven operation modes: Looper, with unlimited looping; Sampling, with resampling and sample sets; Music Composition, which allows loop chaining into Grooves plus effects; Finger Drum via the Scissor-Switch Keys; Keyboard Mode to play the 140 built-in instrument sounds and 14 preloaded grooves plus arpeggiator; Music Game for Casio-style playalongs; and MIDI Mode, which lets you use Wunderkammer WoO.1 as a MIDI controller.
Other functionality includes polyphony (though it doesn’t say how many voices), drag-and-drop sample transfer from your computer via the optional computer app, and effects, including a lowpass, highpass and bandpass filter plus pitch shifter. It offers 44.1kHz/16-bit stereo sound (and also sampling, I would guess). Internal flash storage is 247MB, or about 24 minutes of stereo audio.
Connectivity
Wunderkammer WoO.1 provides a built-in microphone for one-touch sampling, an onboard speaker, a USB-C port for MIDI and charging, and a 3.5mm headphone out. The onboard battery is rated for 50 hours of use via the headphones. This drops to five hours if you’re listening through the speaker.
Price and Availability
Wunderkammer WoO.1 looks like an interesting and fun little sampler. Unfortunately, there’s no input jack for sampling, although Floyd does rate the microphone. Check out his video to hear the unit in action.
Wunderkammer is now accepting preorders for the WoO.1 via its homepage (link below). There’s no price listed, although if you pay a $3 deposit now, you’re guaranteed 35% off the eventual price, a savings of $150 according to the manufacturer. Or you can wait for the Kickstarter, which launches on 19 August.
