This strategic adoption marks a pivotal advancement, addressing long-standing technical limitations, enhancing motion quality, and significantly accelerating development cycles, all while upholding Creative Conners’ commitment to modular, approachable design.
Creative Conners: Revolutionizing Stagecraft for a Diverse Audience
At the forefront of stage automation, Creative Conners has carved out a unique niche by providing robust, versatile motion systems that empower a wide spectrum of users, from professional touring shows and permanent installations to regional theaters and educational institutions. Their philosophy centers on democratizing access to complex stage animations, making them safe, visually compelling, and manageable for both seasoned professionals and enthusiastic amateurs. The company’s vertically integrated approach, encompassing the design and manufacture of machinery, standardized control hardware, and intuitive software like Spike Mark, allows for seamless configuration and deployment across an unusually broad customer base. This means the same foundational technology that orchestrates the awe-inspiring spectacles of Cirque du Soleil or the dynamic concert environments for bands like Dave Matthews can also be found animating school productions of "Les Misérables."
The entertainment industry’s reliance on automation has grown exponentially over the past few decades. Gone are the days when scenery changes were solely manual and performer aerials were rudimentary. Today’s audiences expect fluid transitions, dynamic environments, and flawless execution that often relies on complex, multi-axis motion. Creative Conners identified an unmet need, particularly within the regional theater market, which historically lacked access to the sophisticated automation tools available to larger, higher-budget productions. Their "Stagehand" control box emerged as the cornerstone of this accessibility, serving as a standardized, adaptable controller that interfaces with variable-frequency drives (VFDs), encoders, and critical safety systems. This unit executes precise cues — defining movement paths, speeds, wait times, and coordination with other stage actions — all triggered locally. The Stagehand, therefore, sits at the nexus of hardware, software, and user interaction, making the selection of its embedded motion controller IC absolutely critical to the system’s overall performance, flexibility, and longevity.
The Evolving Demands on Motion Control: Facing Legacy Limitations
For many years, Creative Conners relied on legacy motion control chips from Texas Instruments to power their Stagehand systems. While these devices served their purpose for a time, the accelerating demands of modern stage productions began to expose their inherent limitations. As Christian Basse, Senior Controls Engineer at Creative Conners, articulated, one of the most significant constraints was the inability to achieve independent control over acceleration and deceleration profiles. "On the old IC, we were locked to symmetric accel/decel. Whatever you loaded for the acceleration you had to use for decelerate," Basse explained.
This symmetric constraint directly clashed with both the aesthetic and safety imperatives of stage motion. The visual artistry of a production often requires a rapid, energetic entry of an element onto the stage, followed by a controlled, graceful, and deliberate stop. As Basse highlighted, "We want to hurry up, get onto stage, get moving… but then we want a nice, smooth, deliberate-looking stop." Such nuanced motion is paramount for maintaining audience immersion and ensuring the perceived quality of the production. Beyond aesthetics, the inability to dynamically adjust acceleration parameters was particularly problematic for performer flying effects. These highly sensitive operations require motion characteristics to change on the fly, adapting to real-time conditions and ensuring the performer’s safety and comfort. The legacy IC simply couldn’t provide the granular control needed for these advanced scenarios.
Further exacerbating these technical limitations was the growing issue of availability. The older motion controller was not only aging but also becoming increasingly difficult to source. The global supply-chain disruptions, particularly those triggered by the pandemic, magnified these procurement challenges, threatening Creative Conners’ ability to manufacture and deliver their systems consistently. It became abundantly clear that a new, reliably procured solution that seamlessly integrated with their modular design philosophy was not just an improvement, but an urgent necessity for the company’s continued innovation and market leadership.
A Strategic Partnership: Embracing PMD Technology
Recognizing the imperative for an upgrade, Creative Conners embarked on a comprehensive evaluation of available motion control solutions. After a thorough assessment of various options, the team strategically selected Performance Motion Devices’ (PMD) Magellan MC58113 motion control IC. This decision was not made lightly, given the IC’s central role in the Stagehand platform. The MC58113, paired with a microprocessor and a local HMI display, now forms the sophisticated core of the new Stagehand control PCB, signaling a significant leap forward in Creative Conners’ technological capabilities. PMD, a company renowned for its high-performance motion control solutions across diverse industries, brought a reputation for precision, reliability, and robust engineering to the partnership.

Transformative Capabilities of the PMD MC58113
The integration of the Magellan MC58113 brought a host of transformative improvements to Creative Conners’ stage automation systems, directly addressing the previously identified limitations and unlocking new possibilities:
-
Asymmetric Acceleration and Deceleration: This was the single most impactful improvement. The MC58113’s ability to support independent acceleration and deceleration profiles revolutionized the quality and versatility of motion. This feature allows Creative Conners engineers to program rapid initial movements followed by gentle, controlled stops, fulfilling the aesthetic requirements of theatrical performance and enhancing safety by mitigating sudden jolts. This level of control is crucial for delicate scenic elements and, most importantly, for the smooth and safe handling of human performers in aerial sequences. The precise control over the motion trajectory significantly enhances the visual experience, making movements appear more natural and fluid, a hallmark of high-end productions.
-
Absolute Encoder Support: The MC58113’s support for absolute encoders represents a critical safety and operational enhancement. Unlike incremental encoders, which lose positional data upon power loss, absolute encoders maintain an exact position even when the machine and controls are powered off. As Christian Basse emphasized, "If it’s going to move without the machine and the controls being powered, you’re not going to lose the position." This capability is vital in emergency or rescue scenarios, such as manually lowering a performer using mechanical brakes during a power outage. When power is restored, the system instantly knows its precise location, eliminating the need for re-homing procedures and significantly enhancing operational safety and efficiency. While not universally required, absolute encoders are indispensable for permanently installed infrastructure hoists and for the most demanding, high-end productions pushing the boundaries of stage automation. This feature ensures that Creative Conners can confidently serve clients with the most stringent safety and reliability requirements.
-
Restored Bidirectional Speed Signal: The legacy TI controllers had eliminated the ability to generate a ±10-V speed signal, a functionality crucial for hydraulic valves that interpret negative voltage as reverse motion and positive voltage as forward motion. The MC58113, however, restored this capability through the use of an external digital-to-analog converter (DAC). Basse noted, "Moving to the PMD controller gave us the ability to throw in an external DAC and do a bidirectional signal again." This seemingly specific technical feature is vital for Creative Conners, ensuring they do not have to turn away specialized applications that rely on hydraulic systems, thus broadening their market reach and maintaining their comprehensive service offering.
-
Advanced Diagnostics and Fine-Tuning: The MC58113 comes equipped with built-in tracing and monitoring tools, providing Creative Conners engineers with invaluable insights into motion behavior over time. This capability is instrumental for diagnosing issues, optimizing performance, and ensuring the system consistently meets exacting standards. Furthermore, the controller’s highly tunable position filters enable the system to maintain precise target adherence. Basse reiterated the company’s core value: "We really care about the quality of motion… not just that it looks nice but that it’s where it’s supposed to be when it’s supposed to be." In tightly choreographed productions, positional accuracy is just as critical as the smoothness of the motion, and PMD’s IC provides the tools to achieve both.
Accelerated Development and Engineering Efficiency
Beyond the direct improvements in motion control capabilities, one unexpected yet highly significant benefit for Creative Conners was the availability of PMD’s C-Motion C/C++ software library. Instead of investing valuable engineering resources in writing low-level serial communication code and intricate message-packing routines from scratch, the Creative Conners team could leverage PMD’s robust, command-driven API. Sending a command became as simple as a call to a C-Motion function. "That saved so much time and has been invaluable to us," Basse stated. This dramatically accelerated firmware development, allowing Creative Conners’ relatively small engineering team to pivot their focus from foundational "plumbing" to higher-level functionality, innovative user experiences, and the strategic differentiation of their products. This efficiency gain is crucial for a company that prides itself on continuous innovation and responsiveness to market needs.
