Effect Control Change messages

The parameters of the two internal effectors can also
be changed using Control Change messages.

The bank (user or preset) and effect number are
selected before the parameters are changed. This will
load the appropriate effect settings, so that the effects
of the Control Change settings can be auditioned.

The MIDI channel number of the message is used to
determine which effector is affected by the message:

The parameters to be changed in this way are
accessed following the table below.

Note that the parameter to be accessed must first be
selected using the Non-Registered Parameter Num-
bers as given here in this section:

ters available for the effects. These NRPNs are given below:
