Rigid Audio Ultron is a wavetable-based rhythm sequencer designed for Kontakt 6.7.1 or higher. This innovative virtual instrument combines an 8-step sequencer with wavetable synthesis, offering users a unique approach to sound design and rhythm creation. Ultron features a dual-preset layout, allowing for real-time blending and morphing between two sets of 16 presets each. The instrument’s core is built around Kontakt’s wavetable oscillator engine, providing users with a range of sound-shaping possibilities. Ultron’s interface is divided into several sections, including the main sequencer area, wavetable controls, modulation options, and an effects page. The plugin is designed to cater to both live performance and studio production, offering full host automation and MIDI continuous controller support. With its focus on electronic and bass-heavy sounds, Ultron aims to provide producers and performers with a tool for creating “earth-shattering” basslines and electronic grooves.
Pros:
• Intuitive 8-step rhythm sequencer with per-step control over velocity, noise, wavetable position, and pitch
• Dual-preset layout with morphing capabilities for versatile sound design
• Custom wavetable import via drag-and-drop functionality
• Comprehensive effects section with XY pad for parameter morphing
• Affordable pricing, especially during introductory offer periods
Cons:
• Requires full version of Kontakt 6.7.1 or higher, limiting accessibility for some users
• Limited to 8 steps in the sequencer, which may be restrictive for more complex rhythms
• Lack of comprehensive documentation or manual, potentially hindering full exploration of features
Ultron’s feature set is both diverse and focused, catering to electronic music producers and sound designers. The heart of the instrument is its 8-step rhythm sequencer, which allows for precise control over various parameters for each step. Users can adjust velocity, noise amount, wavetable offset, and semi-tuning, providing a high degree of rhythmic and tonal variation within a single sequence.
The wavetable synthesis engine offers four different shape modes, including pulsewidth modulation and lo-fi (bitcrushing) options. This flexibility in wavetable manipulation allows for a wide range of timbral possibilities, from smooth and clean to gritty and distorted sounds. The ability to import custom wavetables via drag-and-drop further expands the sonic palette, enabling users to incorporate their own unique sound sources into the instrument.
Ultron’s modulation capabilities are enhanced by two dedicated modulation tables for the pitch modulation envelope. This feature allows for complex pitch variations and evolving textures within the sequenced patterns. Additionally, the instrument includes a multimode filter with drive, adding another layer of sound-shaping potential to the output.
The LFO for pitch modulation and volume envelope manipulation provides further options for creating dynamic and evolving sounds. These modulation sources can be used to add movement and interest to otherwise static sequences, making Ultron capable of producing highly animated and expressive electronic textures.
One of Ultron’s standout features is its effects section, which includes a high-quality reverb unit, Native Instruments’ Replika delay, and a unique “flair” effect that adds tuned delays to the signal path. The XY touch pad for parameter morphing in the effects section allows for intuitive and performative control over multiple effect parameters simultaneously, making it well-suited for live performance and real-time sound manipulation.
The dual-preset layout, featuring two sets of 16 presets that can be blended and morphed in real-time, is a powerful tool for sound design and performance. This feature allows users to create complex, evolving sounds by seamlessly transitioning between different preset combinations, opening up possibilities for dramatic sound changes during a performance or within a production.
Ultron’s full host automation and MIDI continuous controller support make it a versatile tool in both studio and live settings. Users can map parameters to hardware controllers or automate them within their DAW, providing a high degree of integration with existing workflows and setups.
When compared to similar plugins, Ultron occupies a unique space in the market. While there are many wavetable synthesizers and step sequencers available, Ultron’s combination of these elements in a Kontakt instrument format sets it apart. Unlike more complex wavetable synthesizers such as Xfer Serum or Native Instruments Massive X, Ultron offers a more streamlined and focused approach to wavetable-based sound design. Its emphasis on rhythm sequencing and preset morphing makes it more akin to groove-oriented instruments like Native Instruments Maschine or Arturia Spark, but with a distinct wavetable flavor. Compared to other Kontakt-based instruments, Ultron offers a more synthesizer-like experience, bridging the gap between sample-based and synthesis-driven sound design. Its ability to import custom wavetables gives it an edge over many fixed-content Kontakt libraries, allowing for greater sonic flexibility and personalization.
This plugin is best for:
• Electronic music producers seeking unique, rhythmic basslines and leads
• Sound designers looking for a quick way to create evolving, wavetable-based textures
• Live performers who need real-time control over complex, morphing sounds
• Producers working within the Kontakt ecosystem who want to expand their sonic palette
Despite its strengths, Ultron does have some limitations. The requirement for the full version of Kontakt may be a barrier for some potential users, and the 8-step sequencer might feel restrictive for those accustomed to longer or more complex patterns. Additionally, the lack of comprehensive documentation could make it challenging for users to fully explore and utilize all of Ultron’s features.
Rigid Audio Ultron is a compelling addition to the world of electronic music production tools. Its combination of wavetable synthesis and rhythm sequencing in a Kontakt instrument format offers a unique approach to sound design and performance. The plugin’s strengths lie in its intuitive sequencing capabilities, flexible wavetable manipulation, and powerful effects section. The dual-preset layout with morphing capabilities provides ample opportunity for creating complex, evolving sounds, while the custom wavetable import feature ensures that users can continually expand the instrument’s sonic possibilities. While it may not replace more comprehensive wavetable synthesizers or drum machines, Ultron carves out its own niche as a specialized tool for creating unique, wavetable-based rhythmic textures and basslines.
