Naada Guan for GeoShred Studio

Naada Guan – Physically Modeled Chinese Double-Reed for GeoShred Studio

EXTREME PITCH FLEXIBILITY AND IN-MOUTH REED DYNAMICS ON A CONTINUOUS SURFACE
Naada Guan runs inside GeoShred Studio, placing the guanzi's exceptionally flexible pitch vocabulary on a multi-row continuous pitch surface. Slide across the grid to bend and glide with a freedom that approaches a bowed string instrument; press into the surface to shape the reed's dynamic response, growl intensity, and tonal weight in real time. The AccelMatrix Naada physical modeling engine generates each note as a continuous acoustic event, and because the instrument is polyphonic, you can sustain harmonic foundations while tracing melodic lines above them, or voice full chords across the surface. GeoShred's integrated FX rack adds EchoMT, Reverb, and AmpCab processing directly in the signal chain.

What's Inside Naada Guan:

• GeoShred's continuous pitch surface with fretless glide, extreme pitch bending, and sliding control suited to the guan's exceptionally flexible melodic vocabulary
• Polyphonic performance: sustain harmonic foundations under melodic lines, voice chords, or layer independent phrases simultaneously
• Direct access to guan model parameters including reed dynamics, embouchure flexibility, and tonal shaping
• Integrated FX rack with EchoMT, Reverb, and AmpCab available as part of the performance signal chain
• Full controller support: MPE controllers, wind and breath controllers, GeoShred Control companion app
• AccelMatrix Naada physical modeling engine generating each note as a continuous acoustic simulation

Two Thousand Years of Silk Road Expression

The guan (guanzi) is one of the oldest Chinese wind instruments, with a documented history of over 2,000 years stretching back along the Silk Road to Central Asia. Its short cylindrical body, typically made from jujube wood, houses a large double reed that the player places entirely inside the mouth, giving direct embouchure control over the reed's vibration with extraordinary flexibility. This in-mouth technique enables extreme pitch bending, sliding, and growling that approaches the expressive freedom of a bowed string instrument. The model captures the guan's distinctively reedy, nasal timbre and its continuous, gesture-driven pitch vocabulary.

GeoShred Studio and GeoShred Control

GeoShred Studio operates as a VST3, AU, or AUv3 plugin inside major DAWs, or as a standalone application. Its isomorphic surface is tuned in perfect fourths, providing a layout where melodic intervals repeat consistently across rows. Pressure and gesture are mapped continuously to instrument parameters, making the surface especially well matched to the guan's extreme pitch flexibility and its in-mouth reed dynamics.

GeoShred Control is a free companion app for iPhone and iPad that connects via USB, adding a second multi-touch expressive surface for live performance. MPE hardware controllers and wind or breath controllers connect directly to GeoShred Studio as well.

FAQ

What is Naada Guan?
Naada Guan is a physically modeled Chinese double-reed woodwind (guanzi) powered by the AccelMatrix Naada engine, running inside GeoShred Studio. It captures the guan's extreme pitch flexibility, nasal vocal-like timbre, and the in-mouth reed control technique that defines the instrument's expressive character.

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 Naada Guan?
Naada Guan works with MPE controllers, wind and breath controllers, the free GeoShred Control iOS companion app, and standard MIDI controllers.

Is Naada Guan polyphonic?
Yes. Unlike GeoSWAM instruments which are monophonic, all Naada instruments support polyphonic performance, allowing chords, layered textures, and ensemble-style playing.
