Arturia’s KeyStep 37 mk2: Hybrid Control Meets Playful Workflow in Hannes Bieger’s Studio

The video opens with Hannes Bieger introducing his Berlin studio—a space where analog and digital tools are woven together into a flexible, hybrid environment. He underscores how the KeyStep 37 mk2 fits seamlessly into this setup, acting as a bridge between classic hardware synths and modern software instruments. Bieger’s workflow is all about finding the right tool for the moment, and the KeyStep 37 mk2’s portability and compact design make it a natural fit for both the main desk and ad hoc setups around the room.

What stands out is how the KeyStep 37 mk2 isn’t just another small keyboard; it’s a deliberate choice for hybrid integration. Bieger points out that, while he owns vintage synths like the ARP 2600 and rare tube-based instruments, the real differentiator these days is not just sound quality but how well a device slots into a broader workflow. Arturia’s controller is shown as a device that can travel—physically and functionally—between different parts of the studio, making it a versatile tool for both analog and digital domains.

Bieger singles out the KeyStep 37 mk2’s arpeggiator as a creative powerhouse, especially compared to the often limited arpeggiators found on many synths. The mutate and spice features are highlighted as tools that go beyond basic note cycling, enabling generative patterns and unexpected musical twists. This isn’t just about repeating notes—it’s about evolving sequences that can inspire new directions in a track.

Equally important is the ribbon controller, which Bieger describes as an invitation to experiment with sound shaping in real time. He demonstrates how the pitch bend and modulation ribbons can be mapped to different parameters, such as pitching only one oscillator in a chord for subtle harmonic shifts. This hands-on control encourages a more playful and tactile approach, letting producers shape sound in ways that might not even be possible on the synths themselves.

The workflow demonstration kicks off with Bieger using the KeyStep 37 mk2 to craft a bassline, leveraging the arpeggiator as the central creative engine. He layers this over a groove from his modular setup, illustrating how the controller can serve as the heartbeat of a track’s rhythmic and melodic foundation. The process is iterative and generative, with the KeyStep driving both inspiration and structure.

As the session unfolds, Bieger moves to pad sounds, again using the KeyStep’s ribbons for nuanced modulation. The ability to assign pitch bend and modulation to different oscillators within a chord allows for expressive, evolving textures. This section makes it clear that the KeyStep 37 mk2 isn’t just a sketchpad—it’s a tool for building up full arrangements, supporting workflows from initial idea to finished jam.

Bieger’s reflections shift from technique to the emotional and psychological impact of the KeyStep 37 mk2. He describes entering a meditative flow state when working with the controller, where creative ideas seem to emerge effortlessly. This sense of inspiration is tied directly to the tactile, responsive nature of the KeyStep’s controls, which encourage experimentation and risk-taking.

He likens creativity to a bank account: you withdraw ideas during production, but you need to refill it through experimentation and new workflows. The KeyStep 37 mk2, in his view, is a catalyst for this process—inviting users to push boundaries and discover new sonic molecules. Bieger also praises Arturia’s ongoing commitment to improvement and quality, drawing a parallel between the company’s iterative approach and his own drive to evolve as an artist.
