In some cases, odd sounds may occur when operating the button or a knob, but this does not indicate a malfunction.
COSM Guitar Section (COSM GUITAR)
This analyzes the principal components of an electric guitar,
and precisely simulates the function of each of the
components.
The number and type of pickups, the number of strings, the
tuning of each string, and each element that plays a part in
creating the tone of a guitar is digitally added to the
vibration produced by the strings of your guitar.
In addition, the VGA-7 detects each strings pitch and
enveloping the shape of the sound. These characteristics
are then digitally applied to the current patchs waveform,
causing it to sound with all of the nuances of your guitar
performance.
