MIDI FUNCTIONS OVERVIEW
Introduction to MIDI Clock
MIDI
is commonly found on drum machines and basic 
keyboard workstations.  It is also commonly supported
on most sequencing softw are.
MIDI
together in musical terminology , using a counting
structure that looks like this:
   BAR : BEAT : PPQ
The
but PPQ is a new one for some.  PPQ stands for P art Per 
Quarter; PPQ is the internal subdivision of the quarter
note.
As
is deemed the master .  The master broadcasts the
MIDI Clock information, and the others will follow the
MIDI Clock data.  
In
whichever device has to work the hardest as the time 
code master .  The 788 is processing a lot of data to 
record and pla y back 8 tracks of 24 bit audio , so it 
will be the master in y our studio.  The drum machines 
and sequencers will follow the 788.
MIDI CLOCK
While 
will help keep the devices together , they typically require
a TEMPO MAP .  The tempo map tells each device what
the time signature and tempo of the song is.  This helps 
each device better anticipate the location of the bars 
and beats, and giv es them the information on how to 
count the beats.  Each device in the MIDI Clock chain 
will need their own cop y of the tempo map.

MIDI TIME CODE (MTC)
Introduction to MIDI Time Code
MIDI
found on more adv anced keyboard workstations and 
software sequencers.  MIDI Time Code works in much the 
same w ay as SMPTE time code, counting time in a video
based language that looks lik e this:
   HOURS : MINUTES : SECONDS : FRAMES
While
category may be new to y ou.  The frame counting refers
to the individual still pictures in a mo ving picture reel.  
For instance, a standard US film (NT SC format) uses 24 
frames per second.  This means that 24 still images are 
flashed ev ery second to create the mo ving image you 
perceive on the screen.

particular rate, but there are some guidelines on which 
rate y ou should probably be using:
30fps
29.97dfps - T elevision work in the US (NT SC format)
25fps - Film or Video in Europe (P AL format)
24fps - Film in the US (NTSC format)
If 
The other rates are specifically for dealing with projects
for film and video production.  If y oure working on a 
project for film or video, ask the project manager what
type of code they w ant to use.
In

workstations should chase the 788.  Probably the only 
time y ou will w ant the 788 to chase MT C is if you are 
locking multiple 788s (or similar machines) together .
MTC Offset Explained
The 
00:00:00:00.  If the project you are working on starts 
at another time location, you can have the 788 
automatically offset the internal time code locations
from the incoming MT C signal.  For example:
If
hour, you can instruct the 788 to use an offset of one 
hour (01:00:00:00).  This w ay, when the incoming MT C
is registering 01:00:00:00, the 788 will chase a time
location of 00:00:00:00.

can send MIDI note messages to an external MIDI sound 
module to create tones, as well.  (It is common pr actice 
to use a snare side stick or wood block sound from a

In
work, the 788 must be set to

Keep in mind that if y ou tell the 788 to chase incoming

when y ou want to mak e the 788 pla y by itself again,
change the SYNC SRC setting back to INT (internal) so
the machine can pla y independently again.
MIDI Machine Control is a simple command set to control
transport commands (ie PLA Y, ST OP, REC, L OCATE etc.)  It 
is important to realiz e that MMC is only transport control,
and has no timing reference for synchronization.  (MT C
