SWAM GEO BASS TROMBONE
GeoBassTrombone – Physically Modeled Bass Trombone for GeoShred Studio
CONTINUOUS GLISSANDO, WIDE-BORE RESONANCE, AND DEEP PEDAL REGISTER IN REAL TIME
GeoBassTrombone runs inside GeoShred Studio, where the bass trombone's continuous pitch capability maps naturally to GeoShred's glide-capable performance surface. Slide across the grid for true continuous glissando between any two pitches; press into the surface to shape dynamics from a delicate soft brass quality to a full fortissimo blast. The instrument's wide bore, dark resonance, and deep pedal register all respond continuously to gesture and pressure in real time. The SWAM engine models the underlying lip buzz and air column physics; GeoShred Studio's integrated FX rack delivers reverb, echo, and amp modeling throughout the performance chain.

What's Inside GeoBassTrombone:
Continuous pitch surface where GeoShred's glide capability aligns naturally with the trombone's slide-based pitch mechanism
Lip buzz dynamics, air pressure, and the instrument's tone character, from the deep pedal register to the upper slide positions, responsive to performance input in real time
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
SWAM physical modeling capturing the bass trombone's wide-bore acoustics, dark tonal weight, and the continuous glissando capability inherent to the slide mechanism
The Bass Trombone's Acoustic Identity
The bass trombone is the lowest member of the trombone family, pitched in Bb, with a wider bore than the tenor that produces a larger, more powerful, and darker sound anchoring the brass section. Its slide mechanism enables true continuous glissando between any two pitches, and one or two rotary valves extend the range into a deep pedal register that delivers brass tones of exceptional depth and weight. In GeoShred Studio, the glide-capable surface maps intuitively to the trombone's continuously sliding pitch character.
GeoShred Studio and GeoShred Control
GeoShred Studio is moForte's professional desktop instrument platform, running as a VST3, AU, or AUv3 plugin or standalone application. The continuous pitch surface's native glide capability makes it a particularly well-matched performance environment for an instrument whose defining feature is continuous pitch movement. Wind and breath controllers connect directly, and MPE hardware integrates natively as well.
GeoShred Control is a free companion app for iPhone and iPad that pairs with GeoShred Studio over USB, giving performers a second expressive surface during live play.

GeoSWAM vs. SWAM Bass Trombone
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 Bass Trombone 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.
