CLOCK PULSE OUTPUT (arpeggio clock)
SYNC > ARPEGGIO Clock Divide
(2 to 24, default: 2)
- sets the ratio of MIDI clocks to output pulses from the clock pulse output.
If set to 1, there will be 1 pulse from the clock pulse output for every 1 MIDI clock. (i.e. 24 pulses per
quarter note)
If set to 24, there will be 1 pulse from the clock pulse output for every 24 MIDI clocks. (i.e. 1 pulse
per quarter note)
Below is a table of values you can set the divide ratio to to obtain a clock pulse at various musical time
intervals:

SYNC > ARPEGGIO Normal/Inverted clock pulse
(default: Normal)
- sets the type of clock pulse sent from the clock pulse output.
Most synths, sequencers & drum machines require this to be set to Normal, but there may be a few that
require it to be set to Inverted.
SYNC > MIDI CLOCK Continue is ignored/= start
(default: ignored)
- If set to ignored, MIDI continue messages are ignored. If set to Continue=start, MIDI continue messages
are treated as if they were MIDI start messages.
PROBLEMS USING MIDI CLOCK
When using the MIDI clock in conjunction with the PRO-4 or our retrofits please note the following. The
Kenton add-on cannot sync the arpeggio if it is not actually receiving the MIDI clock this is not as silly as it
sounds, there are a few points to watch for:-
Some MIDI mergers & patch bays actually remove MIDI clock information from the MIDI data stream or
you may have to enable it for the port you are using.
Users of CUBASE note that the default for MIDI clock is for it NOT to be sent, you will have to go into MIDI
Synchronization page and select MIDI Clock to transmit.
Users of UNITOR/EXPORT on an Atari note that the MIDI clock will only come out of port A, (that is the
Atari's own MIDI port), unless you can re-assign it.
