Naada Viola for GeoShred Studio
Tap into true expression. Naada Viola brings the viola's dark, distinctive alto voice into GeoShred Studio as a polyphonic physically modeled instrument. Play chords, layered harmonic textures, and expressive melodic lines across the full range of the instrument, all responding continuously to pressure and gesture on the pitch surface.
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.
GeoShred Studio Required. Running Naada Viola requires prior installation of GeoShred Studio.
Naada Viola – Physically Modeled Polyphonic Viola for GeoShred Studio
THE ALTO VOICE OF THE STRING FAMILY, NOW FULLY POLYPHONIC
Naada Viola runs inside GeoShred Studio, where the viola's distinctive tonal character is accessible across GeoShred's multi-row continuous pitch surface. Press into the grid to shape dynamics and vibrato; slide between positions for expressive phrasing or sustained harmonic voicings. Naada Viola is fully polyphonic, allowing simultaneous voices for chordal writing, inner-voice harmonies, and rich ensemble textures that go well beyond what a single acoustic viola can produce. The AccelMatrix physical modeling engine powers the underlying acoustic simulation; GeoShred's integrated FX rack adds reverb, echo, and amp modeling as part of the signal chain.

What's Inside:
- GeoShred's continuous pitch surface spanning the viola's full range with portamento, glide, and expressive slide built into the layout
- Full polyphony for chords, layered harmonies, and multi-voice ensemble textures
- Adjustable instrument parameters for shaping the viola's tonal darkness and articulation response
- Integrated GeoShred FX rack including EchoMT, Reverb, AmpCab, and additional processors available in the signal chain during performance
- MPE controller, wind and breath controller, and GeoShred Control companion app support
- AccelMatrix physical modeling engine providing continuous, real-time acoustic simulation
Dark C-String Character and Alto Depth
The viola is tuned a perfect fifth below the violin (C, G, D, A), and its most distinctive quality is the dark, slightly nasal tone of the C string. That unique timbre comes from an inherent acoustic tension: the instrument needs a larger body for its pitch range but must remain small enough to hold under the chin. In GeoShred Studio, the AccelMatrix model captures that characteristic darkness and alto warmth while adding polyphonic capability, making the viola's voice available for harmonic layering, inner-voice writing, and ensemble-style performance.
GeoShred Studio and GeoShred Control
GeoShred Studio runs as a VST3, AU, or AUv3 plugin inside Logic Pro, Cubase, Reaper, and other major DAWs, or as a standalone application. Its multi-row isomorphic surface is tuned in perfect fourths, providing natural melodic continuity across the viola's range and supporting the connected, expressive phrasing that defines string performance.
GeoShred Control pairs with GeoShred Studio via USB and puts a second multi-touch surface on an iPhone or iPad for use during live performance. MPE hardware, wind and breath controllers connect directly as well.

FAQ
What is Naada Viola?
Naada Viola is a physically modeled polyphonic viola instrument that runs inside GeoShred Studio. It is powered by the AccelMatrix engine and provides expressive viola performance with full polyphonic capability on GeoShred's continuous pitch 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.
What's the difference between GeoViola and Naada Viola?
GeoViola is a GeoSWAM instrument designed for detailed monophonic solo performance, closely modeling the behavior of a traditional acoustic viola. Naada Viola is a polyphonic Naada instrument that allows chordal playing and layered textures while still providing expressive performance control within GeoShred.
Can I adjust the viola's tonal parameters?
Yes. GeoShred Studio provides access to the instrument's physical model parameters, allowing you to shape the tonal character, darkness, and response of the viola to suit your performance style.
What controllers does Naada Viola support?
Naada Viola works with GeoShred's built-in touch surface, MPE controllers, wind and breath controllers, and GeoShred Control on iPhone and iPad.
Is Naada Viola polyphonic?
Yes. Naada Viola is fully polyphonic, supporting chords, layered harmonies, and multi-voice textures simultaneously.
