Note that since adjustments to the REV TIME parameter do not take effect immedi-
ately, there is a small delay between adjusting the reverb time by using, for example, a
fader and the new reverb time being applied.
The parameter ranges are as follows.
Parameter
1
REV TIME
0.3–
INITIAL DELAY
0.1–500.0 ms
LOW-EQ
–18.0 dB to +18.0 dB
HIGH-EQ
–18.0 dB to +18.0 dB
1. Actual maximum reverb time depends on the impulse-response data.
The following waveforms show the reverb produced by a snare drum with reverb times
of 500 milliseconds and 2.0 seconds. Initial delay is 0.1 milliseconds; reverb balance is
100%. The third waveform shows how reflections can be delayed by using the Initial
Delay parameter. Here the reverb time is 2.0 seconds; initial delay is 200 ms (exagger-
ated for illustration clarity); and the reverb balance is 50%.
