SYSTEM MESSAGES
SYSTEM EXCLUSIVE
These messages can only be interpreted by an instrument made by the same producer as the transmitter device (in some
cases only by the same model). They mainly relate to the instrument’s sound generation and programming parameters.
The Chorale 1 uses these messages to control all the internal parameters and for switching the voices on and off.
REAL TIME
These messages are used for the real-time control of specific modules or functions of a connected instrument.
These messages include the Start, Stop, Pause/Continue and Clock commands. In the Chorale 1 these messages are
transmitted when the internal sequencer is used, as follows:
START
: the sequencer has started to record or play back a MIDI sequence
STOP
: the sequencer has been stopped
PAUSE
/
CONTINUE: the sequencer is in pause (this function isn't managed by Chorale 1)
CLOCK
: the sequencer speed
The Real Time messages also include the Active Sensing code, sent to keep the dialogue between two MIDI instruments
alive. When the receiver instrument does not receive any MIDI data or the Active Sensing code in a time interval of about
300 milliseconds, it considers the MIDI connection to have been deactivated, so it switches off any notes still active.
Remember that the transmission and reception of this message is optional, so not all instruments are equipped to handle it.
TRANSMISSION OF MIDI CODES
MIDI channels for the Chorale 1 are preset by default but can be modified by the user.
By default they are:
• Channel 1 for Manual II
• Channel 2 for Manual I
• Channel 4 for Bass section
To toggle the transmission of MIDI codes for each section of the keyboard first enter the MIDI mode
by pressing the
[TRANSPOSER]
button for about two seconds. It will start flashing. All the lights
will shut down except for the three Bass section stops. To enable/disable the transmission of MIDI
messages for the three sections turn on/off the respective stops in bass section (note that the section
names are written under the stops). The MIDI message that will be disabled are notes, messages,
Program Changes, Control Changes and some SysEx.
To modify the number of any of the MIDI channels for the MIDI messages transmission, first enter
the MIDI mode as described above, by pressing for approx. 2 seconds the
[TRANSPOSER]
button,
which will start flashing. Now choose one of the three sections to modify its MIDI channel number, by
pushing to the bottom one of the three stops in the Bass sections for approx. 2 seconds (the name of the
section you want to modify is printed in white under the three stops). The LED related to the selected
section will start flashing. At the same time, the stops in the MAN.I and MAN.II sections, which will
now work as a numeric keypad (with the numbers printed in white below them), will blink once
indicating the currently selected channel for MIDI messages transmission. Using the MAN.I and
MAN.II stops as a numeric keypad it is possible to select the new MIDI channel number in the range
from 01 to 15 (it is mandatory to type 2 digits). The first 2 LEDs from the
[TEMPERAMENT]
section will indicate the position of the digit that has to be typed (if the first LED is on, the first digit
has to be typed, if the second LED is on the second digit has to be typed). Once the second digit has
been typed, the LED of the first stop from MAN. I (that has “PG” printed below) will flash five times
to indicate that the new MIDI channel number has been assigned successfully. The LED related to the
section that has been modified will stop flashing. In case the number typed exceeds the valid range, the
procedure is automatically aborted and the previous MIDI channel number is kept. To exit the MIDI
channel select mode, please push again the stop related to the section currently selected.
To return to Normal mode press another time
[TRANSPOSER]
.
Note: MIDI receive is always active.
