AlphaTheta Chordcat Groovebox First Look


It has been a while since we’ve seen any new music production gear released from AlphaTheta, the brand previously known as Pioneer DJ.

AlphaTheta, today has released Chordcat, a new music production tool ‘Find Harmony, Spark Creativity’ – some fresh and inspiring sequencing ideas, paired with an underwhelming sound engine.

Chordcat is a compact, budget-friendly groovebox that puts chord sequencing at the centre of its workflow. It has eight individual tracks each of which can sequence sounds selected from 145 sample-based instruments and 16 drum kits.

Each track has its own polyphonic sequencer with a maximum of 128 steps. These allow for patterns to be input and edited step-by-step or via live recording. Chordcat also allows for basic parameter recording using its XY pad.

Its most notable features, however, are those that focus on chord sequencing. Chordcat features a scale mode, chord function and pre-made chord sets for quickly creating progressions. It also has an innovative Chord Cruiser feature, designed to automatically suggest chord combinations in order to inspire new compositional ideas – particularly handy for those lacking in musical know-how.

Chordcat is an incredibly convenient feeling piece of hardware – it’s only a touch over pocket sized and very light, meaning that it’s definitely something that can easily be thrown into a backpack and used on the go. It can be powered by either AA batteries or USB-C, which adds to the portability.

The headline feature of Chordcat is its Chord Cruiser mode. This is designed to automatically suggest combinations of chords. It’s fairly simple to use in operation – the user selects an initial starting chord using the key/scale functions, and then the 16 buttons of the XY pad light up to present a varying number of compatible chords that could work next in a sequence.

These chords can be auditioned using the XY pad buttons. The user can then select their favourites to assign to the buttons along the bottom edge of the UI. Once assigned these chords can be quickly triggered and sequenced with a single button press. There is also a selection of pre-defined chord sets, which are separate from the Chord Cruiser mode.

Chordcat’s other interesting sequencing feature is the Running Direction function inherited from the Toraiz Squid. This can be used to alter the direction in which a sequence moves around the grid of 16 steps, with right, down, clockwise and counterclockwise options, along with the option to reverse sequences and have patterns bounce back and forth. This is a really fun feature, and a great way to quickly turn a pattern on its head or alter the way that Chordcat’s eight tracks are interacting.

Also, there’s a broad range of sounds on offer, including banks of synth tones, pianos, keyboards, basses and multiple drum kits, the selection within these categories is a little vanilla and there’s little in the way of editing capabilities.

Each sound can have its low pass filter and amp envelope controlled via the XY pad, but there’s not much depth here. The filter has just controls for cutoff frequency and resonance, and the envelope has just attack and release. What’s more, in the case of drum kits, these parameters are shared across every sound in the kit – that is, if you want to shorten the release time on a hat, it will apply to your kick as well.

There are a few effects to add a little character. Chordcat features an arpeggiator, delay and ducker, each of which can be controlled via the XY pad. Kits can have reverb applied via a send too, as well as have their individual levels and pan position adjusted.

AlphaTheta has also released a Chordcat Manager application that promises to make it easy to export and import sequences from the device via USB. In short, Chordcat features some genuinely fresh and inspiring sequencing ideas, paired with an underwhelming sound engine.

The Bela team let us know that they’ve introduced the Bela Gem series, a high-performance audio and sensor system for their PocketBeagle 2 compact single-board computer.

The Bela Gem system is made up of two boards: Bela Gem Stereo and Bela Gem Multi, both designed to transform the PocketBeagle 2 into a powerful platform for real-time audio and sensor processing. The open-source systems are designed to provide the tools needed to create innovative audio projects with minimal setup and configuration.

All Bela Gem systems run on PocketBeagle 2, a 4-core 1.4GHz Linux system, and have:

  • Latency as low as 1ms
  • 8 16-bit analog inputs
  • 16 digital GPIO
  • On-board Qwiik connector
  • USB-A port for wifi/bluetooth
  • Synchronous audio/analog/GPIO
  • Browser-based IDE that launches right in your browser, with even more great tools for learning and building

The Bela Gem Stereo has all Gem features, plus:

  • 2 channels of audio in/out, up to 96kHz and 24 bit
  • On-board TRS jacks
  • 58mm x 45mm x 22mm

It’s priced at $69 (add a PocketBeagle 2 for $28).

The Bela Gem Multi has all Gem features, plus:

  • 10 channels of audio in/out, up to 96kHz and 24 bit
  • Up to 8 are configurable as DC coupled outputs for analog or CV
  • 2 on-board TRS jacks, plus included detachable wings with 8 more (remove the wings for a lower profile)
  • 70mm x 58mm x 32mm (with wings) or 22mm (without wings)

It’s $159 (add a PocketBeagle 2 for $28).

Features:

  • 100 % analog signal path: pure VCO ? Steiner-Parker filter ? Brute Factor drive
  • Syncable LFO: 3 waveforms, tempo-sync or audio-rate for FM craziness
  • Step-sequencer: 8 patterns, up to 64 steps each, with rate & trigger modes
  • Unique VCO: Saw, Pulse & Triangle with Ultrasaw, PWM, Metalizer and a Sub-5th generator
  • Steiner-Parker multimode filter: Low-, High- & Band-Pass with self-oscillating resonance
  • CV/Gate & Audio In/Out: process external signals and patch into modular rigs
  • Patchable Mod Matrix: route LFO, ENV or external CV anywhere; mini-jack cables in the box
  • Brute Factor: from subtle saturation to full intermodulation havoc
  • MIDI DIN + USB-MIDI: plug into any DAW or hardware setup, clock-sync, or use as a master keyboard

The Arturia MicroBrute UFO is available now, priced at $399.
