Introduction to the Arturia KeyStep
Since its launch in January 2016, the Arturia KeyStep has carved out a niche for itself as a go-to keyboard and controller for musicians, particularly those engaged in DAWless setups. Its blend of affordability, functionality, and portability has made it a staple in the synth community. The KeyStep’s compact design, featuring 32 mini keys with aftertouch, has allowed it to fit seamlessly into various setups, whether in a studio or on stage. Now, after nearly a decade, Arturia is set to release the KeyStep mk2, a successor that promises significant enhancements while retaining the core features that made its predecessor so popular.
Key Features of the KeyStep mk2
Design and Build Quality
The KeyStep mk2 retains the compact footprint of the original, making it easy to integrate into any rig. However, one of the most notable changes is its construction. While the original KeyStep featured a robust metal baseplate that contributed to its durability, the mk2 opts for an all-plastic build. This shift has raised concerns among some users regarding its long-term durability, especially for those who rely on their gear for extensive touring or live performances. The trade-off for a lighter weight may come at the cost of resilience, a factor that musicians will need to consider when evaluating the mk2 for their needs.
Connectivity Options
Connectivity remains a strong point for the KeyStep mk2. It includes:
- USB-C for both power and MIDI connectivity
- Five-pin MIDI in and out ports
- Analog sync in and out
- Sustain and expression pedal inputs
- CV and gate outputs for modular gear integration
This array of connectivity options ensures that the KeyStep mk2 can serve as a versatile hub for various musical setups, whether users are working with traditional MIDI gear or diving into the world of modular synthesis.
Innovative Features: Mutate and Spice
Generative Capabilities
One of the standout features of the KeyStep mk2 is its new generative capabilities, specifically the functions known as Mutate and Spice. These features are borrowed from Arturia’s Freak line of synths and are designed to enhance the creative process for musicians.
Mutate
The Mutate function introduces a level of semi-randomness to the creative process. By making small, random adjustments to an arpeggio or sequence, Mutate allows musicians to explore new musical ideas without the need for extensive manual tweaking. This feature is particularly appealing for those who enjoy the process of experimentation, as it can lead to unexpected and serendipitous results. YouTuber Loopop noted that with this capability, “a new benchmark has been set for what a keyboard can do as a compositional assistant.” Users can save their favorite variations as new sequences, providing a way to capture inspiration as it strikes.
Spice
In contrast to Mutate, the Spice function focuses on rhythmic variation. By altering gate lengths, velocities, and introducing ratchets, Spice adds a layer of complexity to sequences. At higher settings, it can even introduce octave jumps, creating dynamic and engaging rhythmic patterns. This feature is particularly useful for musicians looking to add depth and interest to their compositions without having to dive deep into programming or sound design.
Community Reactions
The initial reactions to the KeyStep mk2 have been largely positive, particularly regarding its innovative features. Synth influencer Starsky Carr praised the keyboard for its “loads of fun and loads of inspirational tools.” Musicians and producers are excited about the potential for these new generative capabilities to enhance their workflow and inspire creativity. However, the shift to an all-plastic build has drawn some criticism, with concerns about whether the mk2 can withstand the rigors of live performance and long-term use.
Comparative Analysis: KeyStep vs. KeyStep mk2
Similarities
Despite the changes, the KeyStep mk2 retains many of the features that made the original model a favorite among musicians:
- 32 mini keys with aftertouch
- Compact design for easy portability
- Wide range of connectivity options
These similarities ensure that existing KeyStep users will feel comfortable transitioning to the mk2, while new users will find a familiar yet enhanced experience.
Differences
The most significant differences between the two models lie in the generative capabilities and the build quality. The introduction of Mutate and Spice in the mk2 offers a fresh approach to music creation, allowing for more spontaneous and dynamic compositions. However, the all-plastic construction may deter some users who prioritize durability and resilience in their gear.
Implications for Music Production
The release of the KeyStep mk2 comes at a time when the music production landscape is rapidly evolving. With the rise of DAWless setups and the increasing popularity of modular synthesis, the mk2 is poised to meet the demands of modern musicians. Its innovative features encourage experimentation and creativity, aligning with the current trend of seeking unique sounds and compositions.
Moreover, the integration of generative capabilities into a keyboard controller represents a shift in how musicians approach composition. As tools become more intuitive and capable of generating ideas, the role of the musician may evolve from a traditional composer to a curator of sound, guiding the creative process rather than dictating it.
Conclusion
The Arturia KeyStep mk2 is a significant advancement in the realm of keyboard controllers, offering a blend of familiar features and innovative capabilities. While concerns about its build quality may linger, the potential for creative exploration through its Mutate and Spice functions cannot be overlooked. As musicians continue to seek tools that inspire and facilitate their creative processes, the KeyStep mk2 stands out as a compelling option for both seasoned professionals and newcomers to the world of synthesis.
