Note:
If for some reason the MIDI device does not send start/stop commands but
does provide timing information, you can set the SP-12 to “ready” mode prior to
receiving the MDI signal. Select the desired SP-12 segment or sequence and press
RUN/STOP. The sync light will flash, indicating that the SP-12 is awaiting sync. As
soon as the MIDI master is started and sends out MIDI tempo information to the SP-
12, the sync light will go out and the segment or sequence will start playing.
6E SMPTE SYNC (SYNC 3)
1. To select SMPTE sync, activate the SYNC module and key in 3. In this mode,
the SP-12 can slave to SMPTE time code information coming in the
CASS/SYNC/SMPTE IN jack. Tempo is set by the SP-12’s Tempo function
(Sections 1O and 3H).
2. Selecting SMPTE automatically calls up the SMPTE frames-per-second rate
display. Use the Left Arrow and Right Arrow buttons to choose the desired the
SMPTE rate. You have the following choices:
24 = the standard frame rate for film.
25 = the standard frame rate for European television and video.
30 = the standard frame rate for American television and video
(This is the default).
30df = the standard NTSC colour videotape frame rate.
When the display shows the desired SMPTE frame rate, press ENTER.
3. Enter the SMPTE time code point where you want the segment or sequence
to begin. The SMPTE time code format is HH:MM:SS:FF, where H = hours, M
= minutes, S = seconds, and F = frames (one frame is equivalent to 1/30th of
a second at the 30 frames-per- second rate). When the display shows the
SMPTE start point, press ENTER.
4. To sync to SMPTE, select the desired SP-12 segment or song and press
RUN/STOP. The sync light will flash, indicating that the SP-12 is awaiting
SMPTE (the display will confirm this). As soon as SMPTE time code enters
the SP-12 via the CASS/SYNC/SMPTE IN jack, the display will show the
current SMPTE time code reading.
If the SMPTE time code being read from tape is earlier than the SP-12’s SMPTE start
point, the SYNC light will blink until the tape catches up. When the SMPTE time code
reading matches the start point, the SYNC light will go out and the segment or song
will begin playing.
If the SMPTE time code being read from tape is later than the SP- 12’s start point,
the SP-12 will “fast-forward” through the song or segment to catch up with the tape.
The point at which playback begins depends on the start point and tempo.
