FXAlgs #4-11: Classic ¥ TQ ¥ Diffuse ¥ Omni reverbs
Algorithm Reference-10
Classic Verb and Classic Place:
Classic reverbs are 2-PAU algorithms with early reflections. The late portion consists of an input diffuser; ambience
generator with low shelving filters, lowpass filters, and LFO moving delays; and predelay.
The early reflection portion consists of one delay per channel sent to its own output channel controlled by E Dly L
and E Dly R, and one delay per channel sent to its opposite output channel controlled be E Dly LX and E Dly RX.
Each of these delays also use a Diffuser. Diffusion lengths are separately controlled by E DifDly L, E DifDly R, E
DifDly LX, and E DifDly RX while diffusion amounts are all adjusted with E DiffAmt.
The late reverb and early reflection portions are independently mixed together with the Late Lvl and EarRef Lvl
controls. The wet signal is passed through a final high-shelving filter before being mixed with the dry signal.
