When using MIDI clock in conjunction with the
USB SOLO
, please note the following.
First, ensure that the
USB SOLO
is actually receiving MIDI clock. This is not as silly as it sounds -
there are a number of reasons why it may not be receiving MIDI clock messages in the first place. If
you are having problems, go into the MIDI analyser mode described on page 13 and see if the
USB
SOLO
is actually receiving the MIDI clock messages. If the
USB SOLO
is not receiving clock
messages, here are a few points to watch for:-
Some MIDI mergers & patch bays actually remove MIDI clock information from the 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
the MIDI synchronisation page and select MIDI clock to transmit.
If you have more than one MIDI port attached to your computer, note that MIDI clock does not
necessarily come out of all MIDI ports – it may only come out of a pre-assigned or selected one.
There is more information about MIDI clock problems on our website in the “Information and FAQs”
section.
Clock Stop / Start signal is available at the Aux 2 output if selected as the controller source. Para #42.
Clock with a rate of between 1 and 48 clocks per quarter note is available with positive or negative
going pulses at the Aux 3 output if selected as the controller source. See parameter #44.
The clock rate is selectable using parameter #40. Note that no output will happen unless one of the
following conditions are met:
1) A MIDI start command is received. (Unfortunately not all sequencers send start commands)
2) A MIDI continue is received, immediately preceded by a song position pointer zero message.
3) A MIDI continue is received and “continue = start” is set on.
Sync 24 is available at the DIN socket (5 pin 180 degree DIN connector)
Pin 1 - Stop = 0 volts / 1Start = +5 volts (or continue if selected)
Pin 3 - 5 volt positive going pulses; 24 clocks (pulses) per quarter note, the same as MIDI
Pin 2 - Ground (zero volts)
Pins 4 & 5 are not used.
Sync 24 is always available subject to a MIDI clock signal being present – it is
not
affected by the clock
divide parameter #41, however it
is
affected by the continue = start parameter #40.
