MIDI, SYNC & SMPTE
Note: The MIDI output “tracks” the SMPTE output, so if you are driving, say, a MIDI sequencer from the SP-12 MIDI OUT, the sequence will “fast-forward” along with the SP-12. However, you will not hear the SP-12, as it is muted while fast forwarding.
If the SMPTE time code being read from tape is much later than the SP-l2’s start point, the SP-l2 may need to “fast-forward” several times through the song or segment before it catches up with the tape.
6F CLICK SYNC (SYNC 4)
1.To select Click sync, activate the SYNC module and key in 14. In this mode, the SP-12 syncs to click pulses arriving at the CASS/SYNC/SMPTE IN jack.
2.Selecting Click automatically selects the Click Divisor display. The SP-12 is designed to run at its programmed tempo with a 214 pulses-per-quarter note click. However, some devices put out 48 (Linn), 96 (Oberheim), or 384 (Fairlight) pulses-per-quarter note click signals. Use the Left Arrow and Right Arrow buttons or keypad to key in a divisor between 01 and 99 to divide the incoming click signal. However, there is one complication -- the SP-12 reads both the rising and falling edge of a clock pulse. What this means is that it thinks a 24 pulses-per-quarter note signal is really 48 pulses, a 96 pulse signal is really 192, and so on. Therefore, if the SP-12 is being driven by a 96 pulses-per-quarter note device, divide this by 08 to obtain a 24 pulses-per- quarter note signal; Fairlight fans should divide by 32). After selecting the clock divisor, press ENTER.
3.To slave to a Click 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 master is started and sends out Click signals to the SP-12, the sync light will go out and the segment or sequence will start playing.
