CHOMPI Club gets TEMPO firmware, adds pattern-based tempo-synced groovebox mode

CHOMPI Club has a new personality: TEMPO, a free alternative firmware that reframes the portable sampler from a tape-style looper into a pattern-based, tempo-synced groovebox. “If you’re reading this, it means you’ve unlocked a new personality for CHOMPI: the TEMPO firmware,” the official Chompiclub transcript states, and the release ships with a Pattern Generator, Slice engine, tempo-synced effects and expanded MIDI clock features.

The firmware went live with an official overview video posted March 3, 2026 and is available as a free download for existing CHOMPI Club sampler users. SynthAnatomy and MusicRadar joined the rollout by describing TEMPO as a rhythmic reimagining that converts the original, cutesy screenless sampler into “an entirely new instrument.” SynthAnatomy’s November 11, 2025 update also recalled CHOMPI’s crowdfunding roots, noting “No one had expected the sampler to raise more than $1 million on Kickstarter for development,” and that the device previously received firmware 2.0 with “numerous engine and workflow improvements.”

TEMPO’s core workflow centers on the new Pattern Generator and a Slice engine. The Pattern Generator is described as “a quick and intuitive way to build pattern-based music with your samples” and is based on a multi-mode arpeggiator with note probability and multiple per-engine rest patterns that insert pauses between notes. The Slice engine automatically slices audio files into 16 segments and maps those segments across CHOMPI’s white keys, turning full samples into rhythmic, percussive building blocks.

The firmware also redesigns the FX and per-sample toolset for tempo-based performance. MusicRadar and the official materials highlight a tempo-synced Dual Delay that can be routed into a diffusion reverb, with the delay/reverb chain able to be “spiced up with randomized pitch-shifting, panning and reversing.” Per-sample effects include sample rate reduction and a multi-mode resonant filter, while chaptered demo content walks through Speed & Direction, Multi-Mode Filter, Sample Rate Reduction, and Start & End Points.

TEMPO expands CHOMPI’s MIDI implementation with a strong emphasis on clock synchronization and interfacing with external devices. “This MIDI workflow has a strong emphasis on clock synchronization and interfacing with other external devices. Via MIDI CHOMPI can either act as the master clock for other gear, or it can follow an external clock from external drum machines, DAWs, or other groove boxes,” the Chompiclub transcript explains. “TEMPO’s PATTERN GENERATOR and DELAY EFFECTS will both refer to whichever clock is selected (internal or external). This creates a tightly-synced musical workflow…”

Installation and daily use follow CHOMPI’s SD-first design: the micro SD card must be inserted for CHOMPI to operate, and CHOMPI will detect alternate firmware placed on the card and automatically load it on boot. The official transcript and video name example SD files such as firmware.bin, samples.wav, options.json and presets.json and note that “All CHOMPI users have free access to alternate firmwares, and it's real easy to swap between them.”

The YouTube overview (posted March 3, 2026) includes chapter timestamps that map directly to features: Pattern Generator at 8:27, Slice Engine at 23:39, FX Engine at 14:12, Snapshots at 25:55 and Freestyle Mode at 30:51, and the posted metrics in the supplied material showed 6,070 views, 256 likes and 32 comments. SynthAnatomy frames TEMPO as the first free alternative firmware in a strategy that treats CHOMPI as a hardware platform for future alternate firmware versions, and notes developers Tobias and Chelsea as the original creators whose “experience” concept TEMPO revives. Chase Bliss, which acquired CHOMPI last year, announced the sampler’s renewed availability and said a new hardware version is planned for 2026.

For users the practical takeaway is immediate: TEMPO is a free way to convert CHOMPI’s two-octave mechanical keyboard, built-in mic, seven-voice polyphony and screenless looper hardware into a syncable pattern machine; the company points users to chompiclub.com for downloads, video tutorials, manuals and resources. As CHOMPI shifts from tape looper to platform, TEMPO marks the start of a modular approach to firmware-driven instrument personalities.
