Specifying how knob data is
transmitted (EDIT TX/RX)
This specifies the type of MIDI message that will be used to
communicate with external devices when the front panel
knobs are moved. With the factory settings this is set to
"MODE1."
When transmitting/receiving the MIDI messages of the
knobs in MODE2, only control change data that can be
received by the three devices MC-307, MC-505, and JX-305
will be transmitted.
When transmitting/receiving data between these devices, it
is best to use MODE2.
Procedure
1. Press the [SYSTEM] button, then the [F1 (SYS)] button.
The selection screen for system settings appears.
2. Press the [CURSOR (up)] button to access the screen for
items 1–4.

DEC] buttons.
* If you would like to know the control number assignments for
each knob/slider in MODE1 and MODE2...
refer to RPS Pattern List (p. 176).
Range: MODE1, MODE2
- MODE1: Knob/slider data will be transmitted and
received as control changes and as system exclusive
data.
- MODE2: Knob/slider data will be transmitted and
received as control changes.
The amount of data will be smaller than for MODE1.
* The REVERB section, DELAY section and M-FX section will
also be transmitted as system exclusive messages, regardless of
the mode.
* With MODE1, some control changes will be automatically
converted to a system exclusive message for transmission.
Also, when such a converted exclusive message is received, it
Chapter 7 Environment Configuration and
will automatically be converted to a control change inside the
MC-307.
* If you want the MC-307 to receive MIDI messages that were
transmitted from the knobs/sliders to an external device (and
then re-transmitted back to the MC-307), you must select the
same EDIT TXRX with which the data was originally
transmitted. If this setting is different, MIDI messages will
not be received correctly.
