OPTIONS
Once a musical instrument generates sound vibrations, it
reaches the human ear through various mediating objects,
each of which significantly affects the sound. The material
and configuration of the instrument, the electric/electronic/
magnetic amplifying system, the air and the reverberation of
the room all affect the final sound. Sound modeling, the
latest DSP technology, "virtually" reconstructs these objects. Roland's breakthrough Composite Object Sound
Modeling (COSM)uses the advantages of multiple modeling methods and succeeds in accuratel y emulating
existing sounds, as well as producing sounds that have never before been created.
