SYS-EX (System Exclusive)
These are MIDI messages unique to the MC-307. Part of the
beginning of the data appears in the microscope. For a
complete view of the data, press the [CURSOR (right)]
button.
System Exclusive messages begin with an F0 and end with an
F7 and the data is expressed in hexadecimal (00–7F) form.
* The System Exclusive messages in the MC-307 except for
some of the parameters are compatible with those in the MC-
505 and JX-305. Of the messages contained in the MIDI
implementation, those common to the MC-505 and JX-305 can
interchange data with the MC-307.
* The MC-307 is capable of receiving bulk dumps from the MC-
505 . On the other hand, the MC-505 may fail to receive the
bulk dumps from the MC-307 due to differences in the number
of patches.
Procedure
1. Invoke the microscope screen (P. 72) and using the
[VALUE] dial, position the cursor at the System
Exclusive message you want to change.
2. Press the [CURSOR (left)] button several times.
Chapter 5 Creating Your Own Patterns and
The display changes to the System Exclusive input
screen.
3. Use the [CURSOR (left/right)] buttons to the cursor to
the position you want to change.
4. Change the value using the [VALUE] dial or the [INC/
DEC] buttons.
At this time, you can use the keyboard pads to enter a
hexadecimal number. The hexadecimal digit entered by
each pad is as follows.
1 2 3 4 5 6 7 8 9 0 A B C D E F
5. Pressing [F4 (OK)] button finalizes the edited data.
When the settings have been finalized, you will return to the
normal Microscope display.If you do not want to finalize it,
press the [EXIT] button.
* It is not possible to change the F0 that begins the message or
the F7 that ends it.
* By pressing [F2 (INS)] button you can add the data at the
cursor location.
* Instead, you can add data by positioning the cursor at F7 and
entering a value from the keyboard pad.
* By pressing [F3 (DEL)] button you can delete the data at the
cursor location.
To cancel the operation without changing the data, press
[EXIT] button.
About the checksum
When inputting a Roland Type IV exclusive message, you
must input a checksum immediately before the F7. Since the
MC-307 will calculate the checksum automatically, there is
no need for you to modify the checksum value. When you
input a new exclusive message, you can simply input an
arbitrary number immediately before F7, and the MC-307
will calculate the correct number automatically.
* If you do not want the checksum to be calculated
automatically, set the AUTO CHECKSUM setting (p.
119) to "OFF."
