The landscape of modern digital music production is in a state of perpetual evolution, bridging the gap between raw, organic acoustic performances and the boundless flexibility of the Digital Audio Workstation (DAW). Celemony—the esteemed audio technology innovator globally renowned for pioneering pitch-correction and audio manipulation software through Melodyne—is continuing to shake up the virtual instrument and sample market with its latest ecosystem, Tonalic.
Launched earlier this year, Tonalic was designed to break the mold of traditional static sample libraries. Instead of offering rigid, lifeless multi-samples, the platform captures the nuanced, living performances of legendary session players, virtuosos, and rhythm-section architects—ranging from contributors associated with the Foo Fighters and Evanescence to Dizzee Rascal—and turns them into DAW-ready creative palettes.
Now, Celemony is significantly bolstering this expanding sonic catalog with the introduction of acclaimed Berlin-based upright bassist Paul Kleber. A fixture of the German capital’s vibrant underground, jazz, and pop scenes since the mid-1990s, Kleber brings decades of cross-genre mastery to the Tonalic fold. Recorded live at Berlin’s prestigious LowSing Studio, Kleber’s new content drop not only injects his signature low-end warmth and harmonic dexterity into the platform but also dramatically upgrades Tonalic’s capabilities regarding bowed (arco) upright bass textures.
This major content expansion comes at an opportune time for producers seeking organic rhythm sections without the logistical hurdles of booking live studio sessions. With over 30 world-class musicians now integrated into the Tonalic framework, boasting a repository of more than 7,000 unique performances, the addition of Paul Kleber cements the platform’s reputation as an indispensable tool for forward-thinking producers, film scorers, and beatmakers across the globe.
Detailed Chronology: The Evolution of Tonalic and the Path to Paul Kleber
To truly understand the weight of Paul Kleber’s integration into the Tonalic ecosystem, it is vital to trace the trajectory of Celemony’s ambitions beyond its flagship software, Melodyne. For decades, Celemony was synonymous with precise audio surgery—fixing out-of-tune vocals, reshaping timing, and analyzing polyphonic audio with uncanny algorithmic intelligence. However, the conceptual leap from correcting audio to generating inspiring, ready-to-use musical building blocks culminated in the launch of Tonalic.
The Genesis of Tonalic
Introduced at the beginning of the year, Tonalic was conceived to answer a glaring gap in modern music production workflows. While loop packs and static sample libraries have existed for decades, they often lock producers into rigid tempos, keys, or stale arrangements that resist customization. Conversely, live-recorded multitracks require extensive editing, mixing, and arrangement skills to sit right in a mix.
Tonalic bridged this divide by leveraging advanced audio analysis and flexible software architecture. The platform enlists elite instrumentalists—drummers, bassists, guitarists, and percussionists—to lay down authentic grooves, improvisations, and foundational tracks in professional recording environments. These performances are then meticulously processed, sliced, and mapped so that producers can drag, drop, and manipulate them inside any major DAW with absolute structural and sonic fluidity.
Bringing Berlin’s Low-End Maestro Onboard
As the platform scaled throughout the year, accumulating a roster of over 30 artists and thousands of distinct musical phrases, the curatorial team behind Tonalic sought to expand its acoustic string and upright bass offerings. Specifically, the developers recognized a need to broaden the palette of bowed upright bass—a texture that previously relied on a single, limited set of options within the software.
Enter Paul Kleber. A mainstay of the Berlin music scene for nearly three decades, Kleber’s resume reads like a masterclass in musical versatility. Having provided the foundational low end for acclaimed acts such as Jazzanova Live, the Moka Efti Orchestra, Emilíana Torrini, Fink, Dee Dee Bridgewater, and Nina Hagen, Kleber was uniquely positioned to bridge the gap between traditional jazz upright playing and modern electronic, pop, and funk sensibilities.
The collaboration was officially captured during a series of intensive recording sessions at LowSing Studio in Berlin. Rather than focusing solely on traditional jazz walking basslines, Kleber and the Tonalic production team curated a dynamic collection of performances that highlight both his breathtaking arco (bowed) articulation and his punchy, warm pizzicato (plucked) tone. The resulting expansion pack officially drops this autumn, marking one of Tonalic’s most significant genre-spanning updates to date.
Supporting Context & Metrics: Inside the Tonalic Ecosystem
The integration of Paul Kleber is more than just a routine content update; it highlights a broader shift in how producers source organic instrumentation in the modern DAW environment. To contextualize the scale of this release, it is helpful to examine the operational metrics and design philosophy driving the Tonalic platform.

The Art of the Upright Bass in Digital Production
Synthesizing or programming a convincing upright bass has historically been one of the steepest challenges for electronic and pop producers. Standard sample libraries often sound sterile, lacking the physical resonance, fingerboard squeaks, wood body thumps, and micro-timing variations that give a real upright bass its human pulse.
Furthermore, capturing a truly expressive bowed (arco) upright bass requires pristine microphone placement, high-end preamps, and an exceptional player capable of maintaining flawless pitch and consistent bow pressure across varying registers. By enlisting Kleber—an artist celebrated equally for his delicate, soaring bowed textures and his deeply grounded, driving plucked grooves—Celemony has provided producers with a plug-and-play solution that retains all the warmth and emotional resonance of a world-class studio tracking session.
Official Statements and Industry Perspectives
The announcement of Paul Kleber’s addition to Tonalic has generated considerable buzz among producers, composers, and artists alike. The unique crossover appeal of Kleber’s musical background has been a central talking point for industry insiders evaluating the update.
Paul Kleber on Versatility and the Berlin Club Scene
Reflecting on his career and his philosophy toward session work, Kleber emphasizes that his love for diverse sonic landscapes directly informs his playing style. Far from confining himself to straight-ahead jazz, Kleber’s career has been defined by a restless curiosity that bridges acoustic instrumentation with electronic music culture.
"People book me for studio sessions for several styles, because they know I love several kinds of music," Kleber shares. "I’m not specialised in only jazz. I love to play jazz but pop and funk and electronic music as well."
This eclectic ethos was forged not just in traditional concert halls and jazz clubs, but in the crucible of Berlin’s legendary electronic music underground. Kleber elaborates on his late-night explorations:
"We had several sessions with DJs in a famous club in Berlin called ‘Club der Visionäre.’ There were guys like Ricardo Villalobos, and we jammed the whole night."
This deep-seated familiarity with electronic grooves and hypnotic, repetitive club rhythms allows Kleber’s upright basslines to translate effortlessly into modern DAW environments, where groove, pocket, and hypnotic low-end weight are paramount.
Producer Perspectives on Tone and Articulation
The industry reception has reinforced Celemony’s decision to tap Kleber for the expansion. Musician, producer, and composer Ryan Harlin highlighted the unique sonic advantages that Kleber brings to the software architecture:
"Paul Kleber is not just sought out for his bowing," notes Harlin. "The tone that he gets from plucked upright bass makes this content expansion that much better."
By balancing the smooth, sustained emotional gravity of his bowed performances with the woody punch and rhythmic clarity of his plucked mastery, Kleber’s sets provide producers with an unprecedented degree of dynamic control. Whether scoring an atmospheric cinematic cue, laying down the foundation for an indie-pop track, or adding organic warmth to a deep house groove, the material adapts seamlessly to the user’s creative vision.
Future Outlook: The Intersection of Human Craft and Software Innovation
As the boundaries between live musicianship and software-based production continue to blur, platforms like Tonalic represent a fascinating glimpse into the future of music creation.
