Dual Tap-Reader
As part of the reverb algorithm, the Dual Tap-Reader Os- used to simulate early reflections. The two taps can be up

The samples gathered are then scaled, summed, filtered, sampling rate. However, the reverb system is typically run
and sent to a submix register or one or more output chan- with Half-Speed Oscillators, making possible 160 ms or
nels. Note that the filtering takes place after scaling and more between taps. As many Dual Tap-Readers as de-
summing since there is only one filter in the Dual Tap- sired can be used with a single Tape Loop Oscillator pro-
Reader. The taps supplied by the Dual Tap-Reader can be viding the input (Figure 13).
