1 Reverb Time 0.3~30.0s 0-69 Table#4 This determines the time or length of the Reverb effect.
2 Diffusion 0~10 0-10 This determines the density and complexity of the reflections that make up the
Reverb effect. Lower values result in a clearer, simpler Reverb sound, while
higher values result in a thicker, richer sound.
3 Initial Delay 0~63 0-63 Table#5 This determines the time delay between the direct sound and the first of the many
reflections that make up the Reverb sound.
4 HPF Cutoff Thru~8.0kHz 0-52 Table#3 The High Pass Filter allows you to filter out low frequency sounds from the
Reverb sound, “passing” only the high frequencies above the cutoff point.
This parameter determines the frequency cutoff point for the filter.
Higher values effectively take the bass sounds out of the Reverb effect.
5 LPF Cutoff 1.0k~Thru 34-60 Table#3 The Low Pass Filter allows you to filter out high frequency sounds from the
Reverb sound, “passing” only the low frequencies below the cutoff point.
This parameter determines the frequency cutoff point for the filter.
Lower values effectively take the treble sounds out of the Reverb effect.

HINT : LPF Cutoff Judicious use of the Low Pass Filter helps to create a more natural Reverb sound, since many actual performance environments have a relatively “dead”
sound in which the high frequency reflections are absorbed. On the other hand, you may wish to create a more “live” reverb sound by setting the
High Pass Filter Cutoff above to emphasize the high frequencies.
