COSM Parameters
 
COSM provides 16 types. This section explains the features of each 
COSM, and the functions of the parameters.
 
Explanations for each COSM Type are given on the following 
pages.

Parameters marked by “#1”–“#4” can be selected as a destination 
parameter for matrix control (Destination). These correspond as 
follows.
#1: Destination CSM1/2-PRM1
#2: Destination CSM1/2-PRM2
#3: Destination CSM1/2-LFO-PRM1
#4: Destination CSM1/2-LFO-PRM2
 
Overdrive / Distortion
 
Overdrive produces a natural-sounding distortion 
similar to that produced by a vacuum tube amplifier. 
Distortion produces a more intense distortion than the 
overdrive effect.
 
Wave Shape
 
You can use a variety of waveforms to create and 
distort the sound.
