Naada Erhu for GeoShred Studio

Naada Erhu – Physically Modeled Chinese Erhu for GeoShred Studio

TWO STRINGS, A CAPTIVE BOW, AND A NASAL CRY THAT CUTS TO THE BONE
Naada Erhu reproduces the erhu's distinctive push-pull bowing mechanic and nasal, weeping tone inside GeoShred Studio. On the multi-row continuous pitch surface, every gesture maps to the instrument's expressive behavior: pressure drives bow intensity, lateral movement controls vibrato and pitch bend, and the AccelMatrix Naada engine renders each voice as a real-time physical simulation. The instrument is polyphonic, so you can layer multiple erhu voices into ensemble textures, harmonize melodic lines, or sustain chords. GeoShred's built-in FX rack adds EchoMT, Reverb, and AmpCab to the output signal.

What's Inside Naada Erhu:

• GeoShred's continuous pitch surface with smooth glide, vibrato control, and pitch bend across the erhu's expressive range
• Polyphonic performance: harmonize lines, sustain chords, or build multi-voice erhu ensemble textures
• Erhu-specific model parameters for bow dynamics, vibrato character, and tonal resonance
• Integrated FX rack including EchoMT, Reverb, and AmpCab in the signal chain
• Compatible with MPE controllers, wind and breath controllers, and the GeoShred Control companion app
• AccelMatrix Naada physical modeling engine driving the acoustic simulation in real time

The Bow Between the Strings

What makes the erhu structurally unique among bowed instruments is that the bow hair passes between its two strings, not across the outside. The player pushes toward one string and pulls toward the other, never lifting the bow free. Combined with a small resonating chamber covered in python skin, this produces a nasal, intensely vocal timbre with a weeping quality that has made the erhu one of the most emotionally recognizable instruments in Chinese music. The model captures this confined resonance and the continuous vibrato produced by the player's rocking left hand.

GeoShred Studio and GeoShred Control

GeoShred Studio works as a VST3, AU, or AUv3 plugin within DAWs including Logic Pro, Cubase, and Reaper, and runs independently as a standalone application. The isomorphic playing surface is laid out in perfect fourths, with continuous pressure and gesture response built into every point on the grid. Pitch bends, vibrato, and dynamic shaping happen as natural extensions of how you touch the surface.

GeoShred Control turns an iPhone or iPad into a wireless-free multi-touch controller that connects to GeoShred Studio over USB. MPE hardware and wind or breath controllers plug in directly for additional expressive input.

FAQ

What is Naada Erhu?
Naada Erhu is a physically modeled Chinese two-string bowed instrument powered by the AccelMatrix Naada engine, running inside GeoShred Studio. It captures the erhu's plaintive, nasal tone and its distinctive captive-bow playing mechanic.

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

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