2. The HI-CUT knob controls a low-pass filter which attenuates the high frequencies of the signal as it passes
through the delay. This filter models the extremely limited high-frequency response of analog delay
circuits—a limitation which, ironically, creates much of their “warmth” and pleasing character. The range
of this knob is 4KHz to 8KHz, but that value represents an upper limit. The actual operating frequency of
the filter is also determined by the delay time. Analog delays have less high-frequency response at longer
delay times, so DubStation’s low-pass filter’s frequency also decrease as the delay time increases.
The
LO-CUT knob controls a high-pass filter which attenuates the low frequencies of the signal as it
passes through the delay. The range of this control is 100Hz to 1.5KHz. This filter emulates the poor bass
response of older delays, and is particularly useful for creating the thin-sounding echoes often heard in
Jamaican dub music. Try setting the knob to about 12 o’clock when using DubStation on your next dub
remix.
3. The TIME knob and the MULT switch together control the amount of time that the signal is delayed. If the
MULT switch is in its x1 position, the TIME knob varies the delay time from a minimum of 4 msec to a
maximum of 1000 msec (or one second). The x2 position of the
MULT switch multiplies the delay time by
two, giving the TIME knob a range of 8 – 2000 msec.
You’ll notice that the delayed signal has less high-frequency content than the original signal. At long delay
times, the high frequencies are reduced dramatically. This is an accurate recreation of the frequency-
response characteristics of delays built with analog bucket-brigade delay circuits, and a fundamental
aspect of their sonic personality.
4. If you turn on the SYNC switch DubStation uses the current tempo reported by your VST host to calculate
its delay time. When this switch is on, the time knob sets the delay length in metrical units, that is,
fractions of a beat. The range of values is 1/32
nd to 1/1 (a whole measure), with dotted and triplet times
available. Watch the status display at the bottom of DubStation’s window as you rotate the knob to choose
a delay interval—or just do it by ear. Triplet values are denoted with a “T” after the beat fraction, and
dotted values are denoted with a period. For example, “1/8 .” indicates a delay time with a dotted eighth
note feel. DubStation will track tempo changes, saving you from having to adjust its delay time by hand
when you change the tempo of your song.
The
MULT switch doubles the delay interval when the sync switch is on. DubStation displays “x 2” in its
status display after the beat fraction if the MULT switch is on. For example, “1/16 x 2” indicates an
eighth-note delay interval, since there are two sixteenths in an eighth.
Note that DubStation’s maximum delay time of two seconds still applies when the sync switch is engaged.
If you attempt to use a combination of tempo and beat fraction that exceeds this limit, DubStation will still
only delay the signal by two seconds.
Also note that your VST host must conform to the VST 2.0 specification for DubStation’s tempo
