Description

Step into the realm of limitless sonic exploration with the XILS-Lab PolyKB III, a remarkable tribute to the iconic RSF PolyKobol 2. This analog-modeled polyphonic synthesizer redefines creativity with its groundbreaking morphing oscillators, offering a vast array of analog waveforms that can be dynamically modulated for truly unique soundscapes. The PolyKB III isn't just a recreation; it's an evolution. It introduces two lush multimode filters, enhanced by XILS's exclusive 0df technology, to deliver an exquisite warmth and resonance that captures the essence of classic analog synths.

The PolyKB III's innovative design includes a Per Voice modulation engine with a Voice XY modifier, allowing each note to expressively morph across multiple parameters. This, coupled with the Space XY module, places your sound in a 3D stereo space, enabling stereo scenes that defy traditional limitations. The synth’s giant Step Modulator offers up to 128 steps, allowing detailed rhythmic patterns and trance gates that breathe life into your compositions.

Whether you're crafting a subtle ambient texture or a bold, dynamic lead, the PolyKB III provides a suite of tools to shape your sound with precision and depth. With its True Unison feature, you can create dense, breathtaking audio landscapes that stand out in any mix. Dive into the PolyKB III and unleash a new era of musical creativity.

Critic Reviews

XILS-lab PolyKB III review | MusicRadar

musicradar.com

XILS-Lab's PolyKB III is a standout virtual synth that masterfully emulates the rare RSF PolyKobol 2. Praised for its unique sound, the synth boasts three morphing oscillators and a powerful step sequencer, making it an excellent choice for electronic producers. However, the step sequencer is noted for being fiddly, and the lack of voice position modulation in the XY pads can be a letdown. Despite these quirks, the synth's sound quality, particularly its oscillators and filters, is described as dazzlingly 'real' with an analogue vibe, making it a must-try for enthusiasts.

The XILS-Lab PolyKB III is a sound designer's dream, offering a rich palette for crafting unique analog textures inspired by rare synth classics. With features like morphing oscillators, multimode filters, and a deep polysequencer, it excels in creating lush, evolving soundscapes. However, it can be visually overwhelming with its small, realistic interface, and the sequencer requires patience to master. While not instantly gratifying, its organic, lively tones make it a standout for those willing to dive deep. At a reasonable price, it's a worthwhile addition to any studio, particularly for those craving innovation.
