Aftertouch (channel pressure only
✩
)
Aftertouch is a function that lets you modify the currently sounding notes by
applying pressure to the keyboard after playing a note.
There are two types of aftertouch: channel pressure and polyphonic key pressure.
Channel pressure applies an effect uniformly to all note numbers of a MIDI channel.
Polyphonic key pressure applies an effect only to the key (note number) to which
pressure was applied.
All Sound Off
This message completely silences all currently sounding notes. The corresponding
channel will be forced into silence.
All Notes Off
✩
This message generates a note-off for all notes that are currently on. In the
corresponding channel, all notes that are on will be turned off. However, if Hold 1
or Sostenuto are on, the notes will continue sounding until these messages are
turned off.
Reset All Controllers
✩
This message returns controllers to their default values. The following controllers on
the corresponding channel will be reset to their default values.
Active Sensing
This message allows the receiving device to detect a broken or disconnected MIDI
cable. The SC-D70 transmits an Active Sensing message from MIDI IN at regular
intervals.
Once an Active Sensing message is received at MIDI IN, the receiving unit will begin
monitoring Active Sensing. If 420 milliseconds elapse without an Active Sensing or
other message being received, the receiving unit will decide that the cable has been
disconnected. It will then stop all sounding notes, perform the same processing as
when a Reset All Controllers message is received, and cease monitoring Active
Sensing.
Controller Default value
Pitch bend change 0 (center)
Polyphonic key pressure 0 (minimum)
Channel pressure 0 (minimum)
Modulation 0(minimum)
Expression 127 (maximum)
Hold 0 (off)
Portamento 0 (off)
Soft 0 (off)
Sostenuto 0 (off)
RPN a state in which no number is specified
NRPN a state in which no number is specified
With the factory settings,
receiving aftertouch
messages will not cause the
SC-D70 to apply any effect
to the sound. To make
aftertouch produce an
effect, you must set
aftertouch-related
parameters.
The value of parameters
that were set using RPN or
NRPN will not change
even if Reset All
Controllers is received.
