What Is Cosm - Roland V-Synth GT Quick Start Manual

01

What is COSM?

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.

Overdrive/Distortion
This simulates the sound of overdrive
produced by vacuum tubes, and the in-
tense distortion sounds of a guitar amp.
Amp Simulator
This simulates a guitar amp to add natural-
sounds to prevent distortion.
Lo-Fi Processor
This lets you lower the bit-depth or
sample rate.
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.
Wave Shaping
This allows you to create a distinctive
distortion that is even more intense than
Overdrive or Distortion.
Speaker Simulator
This simulates a speaker. It does not
between the fundamental and the over-
tones, allowing you to create unusual
overtone structures.
TB Filter
This is based on an analysis of the fi lter of
the Roland TB-303.
