The FX Page
When sustaining notes while switching between 2 Programs, FX resources from the first
Program may be "stolen" in order to load effects from the second Program. Because of this,
you may hear a change in the sound of the first Program when switching to the second
Program. If both Programs each use 14 FX Units or less, then in most cases FX resources will
not be stolen from the first Program, and you should not hear a change in the sound of the
first Program.
Insert
Choose an effects Chain that will be applied to the current program. If you only need to use
one Chain at a time on one MIDI channel, Insert effects may be all you need. If you plan
to use multiple programs on different MIDI channels, it is best to use both Insert and Aux
effects (see Aux below). Aux effects have the advantage of being available to all programs on
each MIDI channel at the same time.
Aux 1, Aux 2
Choose an effects Chain for each of the two auxiliary audio buses. An aux bus is an audio
channel with a shared effects Chain that can be used by programs on any of the 16 MIDI
channels. The aux effect is useful when you want to use the same type of effect for multiple
channels (typically used for Reverb or Delay). You apply an aux effect to the program on a
MIDI channel by "sending" the audio from that channel to an aux bus.
Every channel is connected to the aux buses, but the aux buses don't receive the signal until
you turn up the aux "send" level for that channel, which controls a channel's input level to
the aux bus. On each MIDI channel you can control the aux send level for that channel's
program, in turn controlling how loudly you can hear the aux effect applied to that channel's
program. The aux send level is set by the Aux 1 and Aux 2 Send parameters on the FX page.
Many Chains also have an additional Aux send, Wet/Dry, or Amount parameter that will
appear on the PARAMS page. For Reverb and Delay Chains, send parameters are often
assigned by default to Slider 9 or Slider 8 respectively.
Output
The Output parameter specifies the rear panel analog output pair to which the selected aux
bus is routed. Setting the Output to A routes the signal of the selected bus to output pair A.
Setting the Output to B routes the signal of the selected bus to output pair B. This is useful
if you want to control the processed Aux signal with an external mixer or process the signal
with additional external effects.
