Figure 9.2: Setting MIDI Format
From the Format pop-up menu, choose
the MIDI sync format your software uses.
This pop-up menu duplicates the MIDI
Format pop-up menu found in the
SMPTE Reader window (discussed in
Chapter 10). The Studio 4 converts
SMPTE timecode into the MIDI format
set in this pop-up menu. The choices are:
the MIDI sync format your software uses.

•
No Sync: The Studio 4 ignores the
SMPTE input signal. Also, it doesn't
show timecode when striping.

MTC: The Macintosh uses MIDI

DTL: The Macintosh uses Direct

•
DTLe: The Macintosh uses
Enhanced Direct Time Lock to read
the value of the SMPTE signal.
Enhanced Direct Time Lock to read

DTL NOTE: There is one important point
you need to consider when using either
Direct Time Lock or Enhanced Direct Time
Lock: DTL and MIDI Beat Clock use iden-
tical messages. Consequently, any MIDI
Beat Clock messages received by the
Studio 4 merge with DTL messages gener-
ated by the Studio 4, making both messages
unreadable. Therefore, when you sync your
sequencer to DTL, you must not allow any
devices to send MIDI Beat Clock to the
Macintosh. Either stop the device from
sending MIDI Beat Clock, mute the MIDI
Beat Clock messages in the RCM window
or use MIDI Time Code instead of DTL.

Full Message Display
If you choose MTC as the MIDI format,
then every time the Studio 4 achieves
sync, it generates a “Full Message”.
During a normal syncing situation, you
will get only one full message (when the
Studio 4 initially locks to tape). If the tape
is of poor quality or the SMPTE signal
isn't strong enough, additional full mes-
sages are sent. Each full message
increments the counter and provides a
good way to check the quality of your tape
or incoming SMPTE signal. The SMPTE
Reader window doesn't display Full Mes-
sages when you use DTL or DTLe as the
MIDI synchronization format.
