Specifications

or triggering the gate repeatedly for a sound whose level
is relatively constant.
a PreD (Reverb pre-delay time): 0 - 200
Determines the time lag between the direct sound and the
gate reverb sound.
@ Dens (Reverb density): 0 - 10
@ Tone (Gate reverb tone): 0 - 10
Page 31
a Sens (Gate sensitivity): 1 - 100
Determines the sensitivity of the gate trigger to the input
signal. Higher values allow lower level input signals to
trigger the gate. This parameter has no effect unless the
CTL (Control source) parameter below is set to "Sig LR"
or "SigR".
@ CTL (Control source):
SigLR (Input signal of both L and R channels)
SigR (Input signal of
R channel only)
Int. (TRIGGER key or input from CONTROL
IN
jack)
MIDI (MIDI control change message greater than 64)
Note (MIDI note on message)
Determines the control source for the gate trigger.
Use "Sig
LR" source when you want the audio source itself to trigger
the gate. For most purposes, this
setting should be enough.
The other settings are for more specialized applications,
such
as when you want to manually control the gate (by
pressing the TRIGGER key or by pressing a footswitch
connected to the CONTROL IN jack), or for using a
sequencer to automatically trigger the gate via
MIDI (either
with a control change message or note on data).
INPUT
OUTPUT
In a common studio recording application, a slightly
sloppy bass track could be locked in more
tightly to kick
drum by gating
the bass and using the drum sound to
trigger the gate (or, if you wish, by manually pressing the
TRIGGER key in time with the drum). Alternately, if the
kick
drum is part of a sequencer track, the MIDI note
corresponding to the drum could
be made to gate the bass
and lock the two together.
For the above application in which the kick drum
input triggers the gate for the bass, make the
following settings:
I. Route the bass signal to the left channel input, and
the kick drum sound to the right.
2. Set the Reverb Time (RevT; Page I) to 0.0.
3. Set Tone (Page 2) to 10, to make sure the
frequency response of the bass signalflat.
4. Set the Control Source parameter (CTL; Page 3) to
"SigR", so that the right channel is separated
from the
lefr and routed to control the gate.
Another interesting use of the gate effect and the trigger
feature of the
9120 is to use a CD or other audio sound
source
as a kind of "sampled" sound, played from a MIDI
keyboard. First, connect a MIDI keyboard to the 9120
and set the MIDI channels appropriately. Also, connect
the audio outputs of the
CD player to the left and right
channel inputs of the
9120. Set the Reverb Time and
Tone parameters as desired. Finally, set the Control
Source Parameter
(CTL; Page 3) to "Note". Now, when
you play the
CD, the sound will be gated each time you
press
a key on the MIDI keyboard.
E/R (Early Reflection)
This reverb effect emphasizes the distinct early
reflections over the reverberant wash. It is useful for
creating a spacious ambience without sacrificing the
clarity and definition of the original sound. Early
Reflection is
good for simulating outdoor echo effects,
such
as the sound reflections off surrounding buildings,
or the ambience of an open amphitheater or large
auditorium. It is also effective in adding subtle room
"Space" around dry signals (such as digital samples),
enhancing brass parts,
and creating special effects
as reverse reverb.
such
@ Size (EIR room size): 0 - 100
Possible applications of these include triggering the gate
at
a point not possible with the automatic "Sig" setting,
Determines the apparent size of the room or plate by
adjusting the duration of the early reflection sound.
