What is COSM?

01

COSM (Composite Object Sound Modeling) is proprietary Roland technology that uses DSP 
technology to model physical characteristics such as the structure of an object, materials, electric-
ity, electronic circuits, and magnetism in order to calculate the eff ect they have on the sound that
reaches the human ear as vibrations in the air.

The V-Synth GT provides two COSM units as extensions of a conventional analog synthesizer’s fi lters. 
In addition to the fi lters of a conventional synthesizer, these provide unique fi lters found only on the 
V-Synth, such as SBF (Side Band Filter) and TB fi lter. You can also apply various modeling types such as 
amp, speaker, or acoustic guitar body resonances, as well as eff ects such as compressor and distortion.

When you play a chord, the eff ect produced by a conventional eff ect processor will apply 
to the combined sound of all notes of the chord. However the V-Synth GT’s COSM eff ects 
are applied individually to each note within the chord.

produced by vacuum tubes, and the in-

This allows you to create a distinctive

between the fundamental and the over-
tones, allowing you to create unusual
overtone structures.

This lets you lower the bit-depth or
sample rate.

This is based on an analysis of the fi lter of 
the Roland TB-303.
