CHOMPI, New Keyboard promises to make Sampling Fun

Chompi is a super-cute sampler that was inspired by the Casio SK-1.

The creators of CHOMPI – a new sampling keyboard that’s designed to make musique concrète style audio manipulation fast and fun – shared this sneak preview of the portable sampler.

As the video demonstrates, CHOMPI is designed to make it easy to sample sounds and play them back, using the built-in keyboard.

Chompi is a new “magical” hardware sampler and looper that looks to prioritise personality and playability over a lengthy spec list. With its cute carry handle and big-buttoned interface, it is giving us strong ‘My First Electronic Instrument’ vibes, but might also be capable of charming more mature and experienced musicians, as well.

Built on the open-source Electro-Smith Daisy platform, Chompi puts the focus on a simple sample-based workflow that is designed to encourage experimentation. Hit the record button and you can immediately capture a sound via the built-in mic, and this is automatically mapped across the two-octave mechanical keyboard.

The interface provides big, dedicated controls for sampling, pitch, sample editing and effects. CHOMPI also features a looper, so you can record phrases and play over them, and even overdub layers.

Chompi offers seven voices of polyphony and gives you 14 preset slots. You can adjust the sample start/end point, there’s an AD envelope, and the playback speed and direction of the sample can be controlled, as well. The multi-FX section is all on one knob, and provides a multimode filter, lo-fi saturation, a granular delay-reverb and more.

Recordings can be made using the tape-style stereo looper, which enables you to overdub sounds as many times as you like. The transport knob controls tape scrubbing, loop playback speed/direction and other features that are apparently waiting to be discovered.

As you can see, Chompi has no screen, but RGB LED indicators and endless switching encoders give you multi-page parameter control. The MX Cherry switches on the hot-swap enabled keyboard can be replaced and customised as you wish, and the Chompi is said to be built to last.

USB-C powering means that it is also portable – assuming you have a power bank – while other connectivity includes stereo aux I/O, a headphone socket and MIDI I/O (all on 3.5mm jacks). Your samples are stored on a micro SD card.
