FX Control buses can be used with vocoder, compressor, and
gate-type effects.
For details on the effects that be used with FX Control buses,
see "FX Control Buses" on page 733.
As an example, here's how you can use the FX Control bus
following an insert effect.
Example: Gated Reverb
When using a gate effect with reverberant sound, using the
reverberant sound to control the gate may not produce the
desired results because the reverb extends the duration of the
sound. Normally, you will use the un-reverberated sound to
control the gate, as shown in the diagram below.
In this example, we send the sound from the OSC etc. to
IFX1 and process it through an equalizer. IFX1 is sent via
Chain to IFX2 and also sent via "Ctrl Bus" (FX Control
Bus) to FX Control 1. The Envelope Source of IFX3: Stereo
Gate is set to FX Control 1. This allows the gat to be
triggered by a signal other than its input (the reverberant
sound).
REC Bus
NAUTILUS provides two stereo recording (REC) buses:
REC 1/2 and REC 3/4.
Using the REC busses, you can isolate one or more sounds
for recording or sampling–even if the sounds are also being
mixed into the main outputs. For example, you can play a

recording the drums.
Individual Programs, Combi Timbres, Sequencer Tracks
(both MIDI and Audio), audio inputs, and Insert Effects can
all be routed to the REC busses, in addition to their main
output/IFX bus settings.
If you don't need to use the REC bus for a particular sound,
turn it Off.
Setting the REC bus to 1, 2, 3, or 4 lets you record up to four
mono signals simultaneously. Setting it to 1/2 or 3/4 lets you
record stereo signals, including the effects of the "Pan
(CC#08)" setting.
Send1, Send2
These parameters enable you to set the send level of the
signals routed to Master Effects MFX1 and MFX2. The
signal is sent in stereo to master effects MFX1 and MFX2.
This is valid when Bus Select is L/R or Off.
If you are not using any Insert Effects, use Send1 and Send2
of the IFX– Routing page in PROGRAM, COMBINATION,
SEQUENCER, and Song play modes to set the Master
Effect send level (Use the Sampling– Audio Input page in
each mode to set the send level for the audio inputs.).
Send1 responds to CC#93 and Send2 responds to
CC#91.
