Range (Page 2)
MIDI In (On or Off)
This determines whether or not the selected channel will respond to incoming MIDI
messages.
MIDI Out (On or Off)
In the QuadraSynth Plus Piano, this determines whether or not the selected channel
will transmit MIDI messages. However, in the S4 Plus, this parameter has no effect (it
will be shown in lowercase letters in the display).
Group (On or Off)
This determines whether or not the selected channel will respond to MIDI information
that is received on the Group Mix Channel. The Group Mix Channel is set globally for
all Mixes, and can be found in Global Edit Mode, Page 2, Quad Knob [2]. For more
information, see page 44.
Range (Page 3)
The following four parameters determine whether or not specific types of MIDI
information will be received or transmitted, and are set separately for each Channel in
the Mix. These, however, are dependent on how the individual Channels have their
Range Page 2 parameters set (described above).
Pitch-bend and Modulation Wheels (On or Off)
This determines whether or not the selected channel will transmit and receive pitch-
bend and modulation (controller 1) MIDI information.
Aftertouch (On or Off)
This determines whether or not the selected channel will transmit and receive
aftertouch MIDI information.
Sustain Pedals (On or Off)
This determines whether or not the selected channel will transmit and receive sustain
pedal (controller 64) MIDI information.
Controllers (On or Off)
This determines whether or not the selected channel will receive MIDI controller
information which the Controllers A–D and Pedals 1 & 2 are assigned to (these are
assigned to MIDI controllers in Global Mode, Page 3 and 5).
