•

29.97 Drop Frame—NTSC (North 
American) color television frame rate. 
This format runs at 30 Frames/sec-
ond, but has the first two frames 
dropped every minute, except at min-
utes 0, 10, 20, 30, 40 and 50.

•

29.97 Frames/second (Non-Drop)—
Used to sync to NTSC color television 
without dropping frames. SMPTE 
time does not match real-time, but 
playback pitch is unaffected.

•

30 Frames/second (Non-Drop)—
Original NTSC black and white televi-
sion standard. Often used in audio-
only situations since there are no 
dropped frames and the SMPTE time 
is equal to real time.

 

MIDI computer software cannot read 
SMPTE Time Code directly off a tape, so 
the code must be converted into a format 
that the computer can understand. This 
format is called MIDI Time Code (MTC). 
The converter then sends MTC (which 
retains SMPTE’s hour/minute/second/
frame timing information) to the com-
puter to control the playback of MIDI 
sequencers. You use MIDI Time Code to 
synchronize your computer sequence to a 
master SMPTE timing source.

Direct Time Lock (DTL) and Enhanced 
Direct Time Lock (DTLe) are alternate 
MIDI synchronization formats developed 
by Mark of the Unicorn for their Per-
former sequencer. Very old versions of 
Performer require DTL to sync to tape. 
Newer versions of Performer use 

Enhanced Direct Time Lock (DTLe), 
which provides synchronization accuracy 
equal to MIDI Time Code.

The Studio 4 will convert SMPTE time-
code (recorded at one of the five 
supported frame rates) to either MIDI 
Time Code or one of the Direct Time 
Lock formats.
