Ping-Pong Delay
5.6.4
The echoes of this easy-to-use
Ping-Pong Delay
alternate between left and right channels in stereo. The Ping-Pong
Delay uses the same algorithm as the Stereo Delay (p. 66), except the ECHO PAN parameter is replaced by SPREAD.
SPREAD
– Controls stereo width by setting the pan position of the delay outputs from hard pan (100%) to
mono (0%) to swapped hard pan (-100%).
RATIO
– Allows altering the time difference between the two echoes of the ping-pong.
Sweep Delay
5.6.5
The
Sweep Delay
uses the same algorithm as the Stereo Delay (above, p. 67), but adds an LFO-driven stereo
bandpass filter after the outputs of the delay.
START FREQ, STOP FREQ
– These controls set the range of the filter sweeps.
RESONANCE
– Sets the resonance of the filter. Some might describe this as an “intensity” control.
SWEEP TYPE
– Sets the waveform of the LFO that controls the sweeps. See section
information on LFO waveform shapes and phase.
SWEEP RATE
– Sets the speed of the sweeps.
SWEEP TEMPO
– Locks the SWEEP RATE parameter in rhythmic relation to the global tempo.
SWEEP PHASE
– Adjusts the phase differential between left and right sweep LFO waveforms.
Reverse Delay
5.6.6
The
Reverse Delay
simulates the impossibility of a performance from the future being heard backwards in the
present. It does so by using a delay line to first
record
for a set time period and then to play that recording
backwards.
While the first recording plays, the next snippet is being recorded so that reverse playback appears to
continue seamlessly. If you can think of your performance as a train, this is like individually reversing each car in
place instead of flipping the whole thing from front-to-back.
To hear
only
the backwards sound, make sure
MIX
is set to “100%.”
The Reverse Delay uses the same layout as the Mono Delay (
, above) except as noted below:
TIME
– Sets the length of time that the delay line will “record” before reverse playback begins. When
TIME
is
shown in parenthesis, it is being set automatically by the
TEMPO
parameter (see below). Set
TEMPO
to “NONE”
for manual control.
FEEDBK
– Sets the amount of feedback to add additional repeats to the reversed snippets.
ECHO PAN
– Controls the placement of the wet (reverse playback) signal in the stereo field. Note that this is
different than the MIX page BALANCE control, which affects both wet and dry.
