by using a Song Select message to switch songs. (Song
Select messages can be received if MIDI Clock: Global
1–1a is set to External MIDI.)
• MIDI Clock messages from the external device can be
used to make the KRONOS playback a song (set MIDI
Clock to External MIDI, and run the KRONOS's
sequencer). ("Synchronizing the playback of KARMA or
sequencer") You can change the overall settings
(programs, levels, effects) by using song select messages
to switch songs.
Synchronizing the playback of KARMA or
sequencer
The choice of whether the KRONOS will be the master (the
controlling device) or the slave (the controlled device) is
made by MIDI Clock (Global 1–1a).
Note: When MIDI Clock is set to Auto, the KRONOS will
normally operate in the same way as for the Internal setting.
When an external MIDI clock is received from the MIDI IN
connector, the KRONOS will automatically operate as for
the External MIDI setting.
Using the KRONOS as master and the external
MIDI device as slave
Connect the KRONOS's MIDI OUT connector to the MIDI
IN connector of the external MIDI device.
• When you set MIDI Clock to Internal, the KRONOS
will be the master device, and will transmit MIDI timing
clock messages.
KARMA function: The tempo can be controlled from
the KRONOS. At the same time, the performance
generated by KARMA will be transmitted via MIDI. (In
Combination, and Sequencer modes, data will be
transmitted by timbres/MIDI tracks whose Status is
BTH, EXT, or EX2.) An external tone generator
connected to MIDI OUT will sound, and the tempo of an
external sequencer can be controlled.
Sequencer: The musical data can be played back and
controlled on the KRONOS.
Simultaneously, the sequencer playback will be
transmitted via MIDI from MIDI tracks whose Status is
BTH, EXT, or EX2. An external tone generator
connected to MIDI OUT will sound, and the tempo of an
external sequencer can be controlled.
Using the external MIDI device as master and the
KRONOS as slave
Connect the KRONOS's MIDI IN connector to the MIDI
OUT connector of the external MIDI device.
• When you set MIDI Clock to External MIDI, the
KRONOS will be the slave device.
KARMA: The tempo will follow the MIDI clock. If you
play the external sequencer, the KARMA will
synchronize to the external clock.
Even if MIDI Clock is External MIDI and the KRONOS
is being controlled from the external device, the
performance of KARMA will still be transmitted via
MIDI. (In Combination and Sequencer modes, KARMA
will be transmitted from timbres/MIDI tracks whose
Status is BTH, EXT, or EX2.)

Sequencer: It will not be possible to control the playback
from the KRONOS; instead, playback will be controlled
by the external device. If you wish to play the external
sequencer in sync with the KRONOS's sequencer, you
must first set the same time signature and starting
measure locations on both devices.
Even if MIDI Clock is set to External MIDI and the
KRONOS is being controlled from an external device,
musical data will be transmitted by tracks whose Status
is BTH, EXT, or EX2.
Recording MIDI from an external
sequencer
You can record the MIDI output of an external sequencer
into the KRONOS using either synchronized or un-
synchronized MIDI clocks. Each method has its benefits and
caveats, as described below.
In either case, you will need to set up the KRONOS
sequencer for multitrack recording.For more information,
see "Multi (multitrack recording)" on page 94 of the
Operation Guide.
Synchronized clocks
Generally, the best method is to synchronize the KRONOS
to the external sequencer. To do this:
1. Set the Global MIDI Clock to External MIDI.
This lets the external sequencer control both the tempo and
the point at which recording starts.
2. Set the KRONOS time signature to match that of the
external sequencer.
3. Start recording on the KRONOS.
4. Start the external sequencer.
With MIDI Clock set to External MIDI, the KRONOS will
start recording automatically as soon as the external
sequencer starts playback.
Since the two devices are synchronized during the recording
process, measure divisions etc. will be preserved accurately.
Synchronization is also critical if you need to record in
multiple passes, as opposed to all tracks at once.
The one drawback of this method is that any changes to
tempo or time signature will not be recorded. If any of these
are used, you will have to re-create them within the
KRONOS sequencer after recording.
Un-synchronized clocks
If you need to record tempo changes in real-time, instead of
re-creating them later, you can also record without
synchronizing the clocks. To do this:
1. Set the Global MIDI Clock to Internal.
2. Start recording on the KRONOS.
3. Start the external sequencer.
This records incoming MIDI data exactly as it is received,
preserving any tempo changes.
The drawback of this method is that data regarding measure
divisions and rhythmic values will not be preserved. So, this
method is not suitable if you intend to edit the data later.
