Editing Master Compressor (CMP) Parameters

Compressor is an effect commonly used to limit and compress the dynamics (softness/loudness) of an audio
signal. For signals that vary widely in dynamics, such as vocals and guitar parts, it "squeezes" the dynamic
range, effectively making soft sounds louder and loud sounds softer. When used with gain to boost the overall
level, this creates a more powerful, more consistently high-level sound.
This instrument features the Master Compressor applied to the entire sound of this instrument. Although the
preset Master Compressor settings are provided, you can create and save your original Master Compressor by
adjusting the related parameters.
Master Compressor cannot be applied to audio playback or the metronome sound.
