varies the injection length over a range of 0 to 500ms. At a Build Time of 0ms, there is no extension of the
build time. In this case, the Build Env control adjusts the density of the reverberation, with maximum
density at a setting of 50%. In addition to the two build controls, there is an overall Pre Dly control that can
delay the entire reverberation process by up to 500ms.

The amount of the stereo reverberator (wet) signal relative to the original input
(dry) signal to be output. The dry signal is not affected by the HF Roll control.
The wet signal is affected by the HF Roll control and by all the other
reverberator controls. The balance between wet and dry signals is an extremely
important factor in achieving a good mix. Emphasizing the wet signal gives the
effect of more reverberation and of greater distance from the source.
The overall output level for the reverberation effect, and controls the level for
both the wet and dry signal paths.
The reverberation decay time (mid-band "RT60"), the time required before the
reverberation has died away to 60dB below its "running" level. Adjust decay
time according to the tempo and articulation of the music and to taste.
Adjusts low pass Þlters in the reverberator so that high frequencies die away
more quickly than mid and low frequencies. This shapes the reverberation for a
more natural, more acoustically accurate sound.
Adjusts bass equalizers in the reverberator so that low frequencies die away
more quickly than mid and high frequencies. This can be used to make the
reverberation less muddy.
Used to shape the overall reverberation signal's treble content, but does not
modify the decay time. Reduce the treble for a softer, more acoustic sound.
Choosing an appropriate room size is very important in getting a good
reverberation effect. For impulsive sources, such as percussion instruments or
plucked strings, increase the size setting until discrete early reßections become
audible, and then back it off slightly. For slower, softer music, use the largest
size possible. At lower settings, RoomSize leads to coloration, especially if the
DecayTime is set too high.
