Quad>Hall
3-40
The Quad>Hall algorithm, is a 4-voice pitch shifter in series with the Concert Hall
reverb. As in the multi-voice algorithms, each voice has its own delay, level,
feedback, cross-feedback and panning controls. The maximum delay time for
each voice is 1.250 seconds.
In this algorithm, the reverb effect is fixed in position following the pitch shifters,
with a final Mix control allowing control over the amount of reverb in the
processed sound. Quad>Hall is designed for creating pitch effects, and is an
obvious choice for creating sequences of notes or chords, melody fragments, or
small amounts of pitch shift for doubling (or quintupling) effects.
The PCM 81 Concert Hall provides very clean reverberation. It is designed to
remain behind the direct sound — adding ambience, but leaving the source
unchanged. This effect has a relatively low initial echo density which builds up
gradually over time.
