Roli Strobe2 is a powerful and versatile software synthesizer developed by FXpansion, now owned by ROLI. This virtual instrument is designed to deliver authentic analog-modeled sounds with a focus on fast and intuitive sound design. At its core, Strobe2 features a single “super-oscillator” that combines multiple waveforms, a noise generator, and hard sync capabilities. The synth’s architecture is inspired by classic monophonic synthesizers like the Roland SH-101, Oberheim OB-1, and Sequential Circuits Pro-One, but it expands upon these foundations with modern features and polyphonic capabilities. Strobe2 boasts an extensive modulation system called TransMod, which allows for deep sound sculpting and complex parameter interactions. The plugin comes with a comprehensive library of over 900 presets, providing a wide range of sounds from vintage-inspired tones to cutting-edge sound design textures. Its user interface is designed to be both visually appealing and functional, with real-time animated modulation displays and a scalable vector graphics engine for crisp visuals at any resolution.
Pros:
• Intuitive and fast sound design workflow
• High-quality analog-modeled sound engine
• Extensive modulation capabilities with the TransMod system
• Large, diverse preset library with over 900 sounds
• MPE (MIDI Polyphonic Expression) support for expressive performance
• Built-in effects suite with modulation options
Cons:
• Single oscillator design may limit some advanced sound design techniques
• Learning curve for fully utilizing the TransMod system
Strobe2’s feature set is comprehensive and well-thought-out, catering to both beginners and advanced sound designers. The synth’s super-oscillator is the heart of its sound generation, offering a unique approach to synthesis. Users can blend multiple waveforms, including sawtooth, square, and triangle, with individual level controls. The oscillator section also includes a noise generator and a sub-oscillator with its own waveshaping capabilities.
One of Strobe2’s standout features is its oscillator stacking and detuning function. This allows users to create rich, layered sounds by stacking up to four additional copies of the main oscillator. The detuning can be subtle for slight thickening or extreme for chord-like effects. The hard sync function adds another dimension to the oscillator’s tonal possibilities, allowing for classic sync sweeps and aggressive timbres.
The filter section in Strobe2 is equally impressive, featuring a multimode filter with 22 different responses. This includes various lowpass, highpass, bandpass, and notch configurations, as well as more exotic types like formant and comb filters. The filter also includes a gain-compensated overdrive circuit for adding warmth and grit to the sound.
Strobe2’s modulation capabilities are where it truly shines. The TransMod system allows for complex modulation routings with up to 16 slots. This system enables users to modulate almost any parameter within the synth, including effect parameters. The modulation sources include LFOs, envelopes, and more exotic options like Euclidean sequencers and curve generators.
The synth includes a powerful arpeggiator with advanced features like pattern editing and rhythmic variations. This, combined with the built-in step sequencer, allows for creating complex, evolving patterns and rhythms.
Strobe2 also comes with a comprehensive effects suite, featuring over 25 different processors. These effects can be loaded into six slots and include standard options like reverb, delay, and chorus, as well as more unique offerings like frequency shifters and granular processors. The ability to modulate effect parameters using the TransMod system adds another layer of sound design potential.
The plugin supports MPE, making it compatible with expressive controllers like ROLI’s own Seaboard. This allows for nuanced, multidimensional control over sounds, enhancing the synth’s performance capabilities. Other notable features include microtuning support, allowing users to import custom scales in the Scala format, and a preset morphing function that enables smooth transitions between different sounds. The synth also includes a randomization feature for generating new sounds and a lock function to preserve specific parameters while changing presets.
When compared to other virtual analog synthesizers, Strobe2 stands out for its unique super-oscillator concept and extensive modulation capabilities. While synths like u-he’s Diva or Arturia’s V Collection offerings may provide more authentic emulations of specific vintage hardware, Strobe2 takes a more hybrid approach, combining classic analog-style synthesis with modern digital features. In terms of workflow and ease of use, Strobe2 is more streamlined than complex modular-style synths like Native Instruments’ Reaktor or VCV Rack. However, it offers more depth and flexibility than simpler virtual analog synths like TAL-U-NO-LX or Synth1. Strobe2’s TransMod system is comparable to the modulation matrices found in synths like Xfer Records’ Serum or LennarDigital’s Sylenth1, but it offers a more visual and intuitive approach. The synth’s MPE support puts it in the company of modern, expressive instruments like ROLI’s own Equator2 or UVI’s Falcon, though these tend to offer more extensive sampling capabilities.
This plugin is best for:
• Sound designers looking for a fast, intuitive workflow
• Musicians seeking authentic analog-style sounds with modern flexibility
• Producers who want a versatile synth capable of a wide range of tones
• Performers using MPE-compatible controllers for expressive playing
• Electronic music producers needing both classic and cutting-edge synth sounds
Strobe2 is a powerful and versatile synthesizer that successfully bridges the gap between classic analog sound and modern digital flexibility. Its unique super-oscillator design, combined with the extensive TransMod modulation system, allows for a wide range of sonic possibilities, from vintage-inspired tones to complex, evolving textures. The synth’s intuitive interface and fast workflow make it accessible to beginners, while its depth and modulation capabilities provide ample room for advanced sound designers to explore. The inclusion of MPE support and a comprehensive effects suite further enhances its versatility, making it suitable for both studio production and live performance. While the single oscillator design may be limiting for some advanced techniques, the stacking and detuning features largely mitigate this limitation. Overall, Strobe2 offers a compelling package for musicians and producers seeking a powerful, analog-modeled synthesizer with modern features and an emphasis on fast, intuitive sound design.
