Performing with an external MIDI device
 
Pitch Bend Change
 
This message transmits whatever motion is made by the Pitch Bend 
lever.
 
Aftertouch
 
These messages indicates how strongly the keyboard was pressed 
after playing a note. There are two types of Aftertouch message: 
Channel Aftertouch, which applies to an entire channel; and 
Polyphonic Aftertouch, which applies to individual notes.
The RS-70 cannot transmit Aftertouch messages when its keys are 
pressed. Instead, you can do this by transmitting the Aftertouch 
assigned to the D Beam, Modulation lever, a pedal, or a knob.
 
Program Change
 
This message changes the instrument sound. You can switch Tones 
and Rhythm Sets on the RS-70 using program numbers 1–128 (p. 
132).
 
Control Change
 
These are messages used for increasing performance expression. By 
assigning Modulation (CC# (Controller Number) 1), Pan (CC#10), 
Expression (CC#11), and other Control Change messages to the 
Modulation lever, pedals, and knobs, you can then use these controls 
to change Performances (p. 126).
Bank Select (CC#0, CC#32) messages are used in combination with 
Program Change messages to switch Patches and Rhythm Sets (p. 
132).
 
System messages
 
This category includes exclusive messages, messages used for 
synchronization, and messages that keep a MIDI system running 
correctly.
 
Exclusive messages
 
Exclusive messages are messages used for exchanging patches and 
other kinds of data between compatible devices from the same 
manufacturer.
If messages exchanged using MIDI were limited only to those that 
conform to the universally shared MIDI specifications, it would not 
be possible to transmit messages that are unique to a particular 
manufacturer, or that are designed specifically for a certain device. 
For this reason, MIDI allows for an exclusive format for each 
manufacturer, which can be used to exchange a variety of messages.
On the RS-70, you can use Exclusive messages to store Patch settings 
and other data to sequencers (p. 76).
 
Using the RS-70 to play an 
 
external MIDI sound module
 
By connecting the RS-70 to an external MIDI sound module with a 
MIDI cable and setting the channels, the external MIDI module can 
be used to produce sound when you play the RS-70’s keyboard. 
 
Connecting to external MIDI sound 
modules
 
Example 1:
 
Connecting to one external MIDI sound module
 
fig.r10-05.e
 
Example 2:
 
Connecting to two external MIDI sound modules
 
fig.r10-06.e
 
* Messages received at the MIDI IN connector are output from the MIDI 
THRU connector unchanged.
 
Example 3:
 
Connecting to three or more external MIDI sound 
modules

About MIDI Implementation Charts
Although a variety of messages for performances can be 
handled using MIDI, depending on the functions of the 
connected device, the messages that can be sent and received 
may differ. To see which types of MIDI message a device can 
transmit and receive, refer to the MIDI Implementation Chart 
that is included in the manual of each device. Messages which 
are marked by a circle in the charts of both devices can be 
transmitted between the two devices.
