MIDI SYNC OPERATION
Using an external MIDI converter such a the YAMAHA YMC-10, it is possible to synchronize MIDI equipment such as
sequence recorders, digital rhythm programmers, MIDI computers and similar equipment to playback of material
recorded on the MT3X.
A simple MIDI sync system example is given below. In
this example, the YMC-10 MIDI Converter converts the
MIDI clock signal output from the RX8 Digital Rhythm
Programmer to an FSK (Frequency Shift-keyed) audio
signal that can be recorded on tape. And, in reverse,
the YMC-10 re-converts the FSK sync signal from the
tape back to a MIDI clock signal that can control the
RX8. Before any material is recorded on the tape, the
MT3X SYNC switch is turned ON, the rhythm pattern
programmed into the RX8 is played back, and the re­
sultant sync signal from the YMC-10 is recorded onto
track 4 using normal recording procedure. Now, if the
RX8 is set to “EXTERNAL SYNC” (allowing it to be
controlled by external MIDI signals) and the tape is
played back, the RX8 will start, run, and stop in re­
sponse to the sync track. Once this has been done, it is
possible to overdub and even ping-pong the remaining
three tracks on the tape, using the RX8 rhythm as a
reference. Since the sync track is controlling only the
speed and start/stop timing of the RX8, the rhythm pat­
tern can be edited and re-programmed as required
without losing synchronization.
The same basic principles apply to synchronization of a
MIDI sequence recorder, MIDI computer or other
equipment. If a large number of external sources are
synchronized to tape, a small supplementary mixer
may be required to combine the source signals into a
stereo signal which can be returned to input channels 5
and 6 of the MT3X mixer.
