Set the modulation intensity
▪ While in the FX Edit page (for both the insert or master effects), use the Amt
(Amount) parameter to set the intensity of modulation. This is an offset to
the normal value received from the source.
Feeding the master effects back to the MFX1 input
Master effects are set in parallel, but you can set them in a serial chain by
sending the output of the M FX2 or M FX3 processor back to the input of the
M FX1 processor. This is useful, for example, to send a guitar amp simulator
to the reverb and create an additional insert; or to send a delay into a reverb.
▪ While in the Master Effects > FX A/B page, use the to FX1 parameters to set
the amount of the MFX2/MFX3 signal to be sent back to the MFX1 processor.
