GeoPizzBass for GeoShred Studio

Acoustic bass that comes alive under your fingers. GeoShred Studio's pitch surface transforms your pressure and gesture into plucked double bass expression: string tension, pluck depth, and body resonance all respond continuously in real time. Shape every nuance of attack directly from the grid, from a cushioned ballad pluck to a forward, punchy jazz tone.

Works with MPE controllers, wind and breath controllers, and GeoShred Control, a free iPhone and iPad companion app that delivers a multi-touch expressive surface for live performance.

GeoPizzBass – Physically Modeled Pizzicato Double Bass for GeoShred Studio

PLUCK DEPTH, STRING TENSION, AND BODY RESONANCE IN REAL TIME
Inside GeoShred Studio, GeoPizzBass puts the plucked double bass on a continuous pitch surface where finger position and pressure determine tone, attack, and resonance in real time. The multi-row layout follows the double bass's natural tuning in perfect fourths (E, A, D, G), making walking lines, melodic runs, and harmonic bass movement feel physically intuitive. Audio Modeling's SWAM engine models the complete physical behavior of string, bridge, and body as an ongoing acoustic event. The difference between a cushioned ballad tone and an aggressive bebop attack comes directly from pressure and gesture on the surface. GeoShred Studio's integrated FX rack delivers reverb, echo, and amp modeling throughout the performance chain.

What's Inside GeoPizzBass:

Continuous pitch surface tuned in perfect fourths, matching the double bass's interval layout for natural melodic and harmonic movement
Pressure and position drive pluck depth, string tension response, and body resonance variation in real time
GeoShred's integrated FX rack including EchoMT, Reverb, AmpCab, and more available throughout performance
MPE controller, wind and breath controller, and GeoShred Control companion app support
SWAM physical modeling focused exclusively on pizzicato technique, from a whispered ballad tone to a full, forward jazz pluck

The Plucked Bass's Acoustic Identity

The double bass is the largest member of the bowed string family, but in jazz from the swing era forward it is predominantly played pizzicato, the bow set aside entirely, strings plucked directly by the right hand. Unlike a plucked electric bass or guitar, the upright bass's long string length, high tension, and large acoustic body create a tone with a pronounced fundamental, fast initial transient, and warm decaying resonance that gives a jazz rhythm section its sense of forward motion. GeoPizzBass models that complete acoustic event as a continuous simulation, so the difference in touch between a bassist playing loose and fat versus tight and punchy translates directly into the model's output.

GeoShred Studio and GeoShred Control

GeoShred Studio is moForte's professional desktop instrument platform, running as a VST3, AU, or AUv3 plugin inside your DAW or as a standalone application. Its multi-row isomorphic surface tuned in perfect fourths maps intuitively to bass playing. Melodic movement, chromatic runs, and large interval jumps that would be awkward on a piano layout feel natural on the grid. Pressure response and real-time gesture mapping are native to the platform from the ground up.

GeoShred Control pairs over USB with GeoShred Studio, delivering a multi-touch iOS surface during live performance. Wind controllers, breath controllers, and MPE hardware connect directly as well.

GeoSWAM vs. SWAM Double Bass

GeoSWAM instruments run inside GeoShred Studio and are built around GeoShred's expressive performance surface, including its multi-row grid, continuous pitch layout, pressure response, gesture control, and integrated FX rack. The instrument's core parameters are curated and mapped for immediate, real-time musical control within the GeoShred environment.

SWAM Double Bass is Audio Modeling's standalone instrument and plug-in, which can operate independently or inside a DAW. It provides deeper access to advanced model parameters and detailed customization within its own interface.

Both use the same underlying SWAM physical modeling technology and are capable of highly expressive performance. The difference lies in interface design, parameter depth, and workflow architecture.

They are separate products developed independently, and there are no upgrade or crossgrade paths between the two product lines.

FAQ

What is GeoPizzBass?
GeoPizzBass is a physically modeled plucked double bass powered by SWAM technology from Audio Modeling, running inside GeoShred Studio. It delivers pluck depth, string tension, and body resonance in real time with continuous pitch control, pressure-responsive dynamics, and real-time expression across GeoShred's performance surface.
What's the difference between GeoSWAM and Naada instruments?
GeoShred offers two families of physically modeled instruments: GeoSWAM and Naada. While both deliver deeply expressive performance through GeoShred's touch surface and MPE support, they come from different modeling technologies and are designed with different musical goals in mind.

GeoSWAM instruments are developed in collaboration with Audio Modeling and are closely related to their acclaimed SWAM instruments. These models focus primarily on Western orchestral and acoustic instruments such as brass, woodwinds, and strings. GeoSWAM instruments are designed for highly detailed expressive solo performance and operate as monophonic instruments, just like their real-world counterparts.

Naada instruments are developed by AccelMatrix and emphasize a broader palette of global instruments, including instruments such as Bansuri, Sitar, Veena, and many others alongside selected Western instruments. In contrast to GeoSWAM, Naada instruments are polyphonic, making them ideal for chords, layered textures, and rich ensemble-style performance.

In short:
GeoSWAM: monophonic, orchestral focus, highly detailed solo performance
Naada: polyphonic, broader global instrument palette, ideal for chords and layered textures.

Both instrument families share the same expressive GeoShred performance environment, giving players an intuitive and powerful way to perform physically modeled instruments.
Do GeoSWAM and Naada instruments use the same parameters?
No. Because the two families use different modeling technologies, each instrument includes its own parameter set tailored to its physical model. These parameters control aspects of the instrument's behavior and performance response.
What controllers work with GeoPizzBass?
GeoPizzBass works with MPE controllers, wind and breath controllers, the free GeoShred Control iOS companion app, and standard MIDI controllers.
Is GeoPizzBass monophonic?
Yes. Like all GeoSWAM instruments, GeoPizzBass is monophonic, mirroring the behavior of its acoustic counterpart. For polyphonic performance, GeoShred Studio offers the Naada instrument family, which supports chords, layered textures, and ensemble-style playing.
