12 – MMC and MIDI functions–Control Change messages
TASCAM 788 Digital PortaStudio 107
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:
NRPN values for multi-channel and stereo dynamics processors
26 Aux Pan 1 through 64 through 127 = L63 through C through R63
27 Cue Level 0 through 100 through 127 = –

through 0 through +6 dB
28 Cue Pan 1 through 64 through 127 = L63 through C through R63
80 EQ SW 0, 1 = OFF, ON
81 Effect Post 0, 1, 2 = OFF, PRE, POST
82 Aux Post 0, 1, 2 = OFF, PRE, POST

a.The 788 makes extensive use of Non-Registered Parameter
Numbers (NRPNs) in order to address the large range of parame-
ters available for the effects. These NRPNs are given below:

number) *1
