Stembox standalone DJ solution for controllers debuts with touchscreen

Stembox standalone DJ solution for controllers is a product line that turns any DJ controller into a standalone unit using a combination of software and optional hardware, enabling performance without the usual laptop setup. The system is built around a Rekordbox USB workflow in which users prepare music in Rekordbox, export it to a USB stick, and Stembox reads that stick directly. Stembox Software is offered as a one-off lifetime license for Windows and macOS and can be used on up to two computers. The Stembox website includes a browser-based compatibility checker and advertises a five-day trial, although the trial page states it is not currently being offered.

The product line includes Stembox Display, which adds a 15.6-inch Full HD IPS touchscreen that connects over USB-C while the computer still handles processing, and a Stembox Pro+ variant that integrates a board inside the screen so no computer is required; Pro+ is listed as coming soon. Prices are listed at €129 for Stembox Software, €229 for Stembox Display, and €389 for Stembox Pro+. Any MIDI controller plugged into a Stembox setup can drive playback and audio outputs continue to come from the controller as usual. Stembox supports stems and offers features such as two- or four-deck operation, eight pads across multiple modes, tempo-synced effects, a Drum Station and a Loop Saver.

Stembox product line is offered in three versions with distinct pricing: Stembox Software at €129, Stembox Display at €229, and Stembox Pro+ at €389. Stembox Software is sold as a one-off lifetime license for Windows and macOS and the license allows use on up to two computers. Stembox Pro+ is listed as coming soon.

Stembox Display adds a 15.6-inch Full HD IPS touchscreen that connects over USB-C while the computer still handles processing. Stembox Pro+ includes a board inside the screen so no computer is needed. The system is built around a Rekordbox USB workflow in which users prepare music in Rekordbox, export it to a USB stick, and Stembox reads that stick directly.

Stembox uses a Rekordbox USB workflow in which users prepare music in Rekordbox, export it to a USB stick, and Stembox reads Rekordbox-formatted sticks directly, including playlists, beatgrids, hot cues and keys. Stems separation is performed inside Stembox on the user’s machine before a set, with the separation process described as taking a few minutes per track, and stems then run on the pads of any connected controller on a per-deck basis. The software provides an FX Part Select function that can send an effect to a single element while leaving other elements unchanged, and it also offers a Drum Station and a Loop Saver feature for performance workflows.

Stembox supports two- or four-deck operation along with features such as a three-band EQ, sync, quantize, master tempo and key sync to match typical DJ performance needs.

Stembox is compatible with standard MIDI controllers, enabling those controllers to drive playback when connected, while audio outputs remain routed from the controller as usual. Supported operating systems for Stembox Software are Windows and macOS, and the Stembox Display option adds a 15.6-inch Full HD IPS touchscreen that connects over USB-C while processing remains with the computer.

The Stembox Pro+ variant includes an internal board inside the screen so no computer is required and is listed as coming soon. The Stembox website provides a browser-based compatibility checker, and a five-day trial is advertised on the site though the trial page indicates it is not currently being offered.

Stembox software is designed to enhance DJ performance by turning any controller into a self-sufficient unit. It offers the flexibility of using either two or four decks, allowing DJs to tailor their setup according to their performance style. An essential component of the software is the three-band EQ, which provides refined control over the audio output, enabling DJs to adjust bass, mid, and high frequencies seamlessly. The inclusion of features such as sync, quantize, and master tempo enhances the ease of beat-matching across tracks, which is crucial for maintaining a coherent and dynamic audio flow.

The software also supports key sync, which aligns the key of one track with another, ensuring musical harmony during transitions—a feature prized for both live performances and recorded sets. DJs can exploit the versatility of eight pads per deck, which operate across various modes including hot cues, beat jump, auto loops, 16-slot sampler, key shift, and momentary effects. These pads allow for creative control and manipulation of tracks in real-time, offering diverse performance opportunities.

Effects are a significant part of any DJ’s arsenal, and Stembox includes seven tempo-synced effects, alongside additional effects on channel knobs. This functionality allows DJs to apply dynamic changes to their sets, enhancing the audio experience. Mix recording is integrated, making it straightforward to capture performances for playback or sharing.

One of Stembox’s standout features is its support for stems—individual elements of a track like drums or vocals—which can be controlled separately on the pads. The separation of stems is completed on the user’s machine prior to a performance, taking a few minutes per track. The FX Part Select function further extends this flexibility by enabling effects to be applied to a single element without altering others, offering granular control for performance-tailored sound. As a whole, Stembox software enriches the DJ’s toolkit with robust, performance-enhancing features.

Stembox products are reported to lack certain common DJ and performance features: mic and aux inputs, timecode vinyl support, a booth output, broadcasting capabilities and an Auto DJ function. These items are listed as missing from the Stembox offering in the available material describing the product’s capabilities and limitations. The available sources do not provide this information.
