COSM List
COSM Parameters
COSM provides 15 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.
Overdrive / Distortion OD/DS (p. 111)
Wave Shape W-SHAPE (p. 111)
Amp Simulator AMP (p. 112)
Speaker Simulator SPEAKER (p. 112)
Resonator RESONATOR (p. 112)

2nd order SideBandFilter SBF2 (p. 113)
Comb Filter COMB (p. 113)
Dual Filter DUAL (p. 113)
TVF TVF (p. 114)
Dynamic TVF DYN-TVF (p. 114)
Polyphonic Compressor COMP (p. 114)
Polyphonic Limiter LIMITER (p. 115)
Frequency Shifter F-SHIFT (p. 115)
Lo-Fi Processor LO-FI (p. 115)
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.
