data will b© too large for the MIDI filer’s buffer. No more than 25% of memory should be full
when saving to a DX-7IIFD or its buffer will be filled as well. The MMT-8 will automatically
receive MIDI system exclusive sequence data from any of these devices without having to
select a specific page. If the system exclusive data starts to come in, the display will read:
RECEIVING DATAFROM
MIDI......
This display will remain until the data has been completely loaded, afterwhich the MMT-8
will return to song 99. Note that any time the MMT-8 receives sequence data from MIDI,
any data previously in memory will be lost.
SYNCING THE MMT-8 TO TAPE
It is possible to sync the MMT-8 to a tape recorder with the help of the TAPE SYNC mode.
In this mode, the MMT-8 reads a master clock pulse from a track of a tape recorder, which
keeps all of the s^uencers/drum machines perfectly in time with the recorded information
on the tape machine. This method has the advantage of eliminating the need to print drum
machine or synthesizer parts on tape, since you can use the master clock recorded on tape
(or "sync track") to trigger the drum machine and synthesizers via the sequencer.
RECORDING THE SYNC TONE
Before recording any audio information on the tape machine, you must lay a "Sync Tone"
down on one track of the tape machine. This is usually done on an outside track (track 1 or
8 on an eight track machine; track 1 or 16 on a sixteen track machine; etc.) to keep the
crosstalk to a minimum.
1) Connect the TAPE OUT jack of the MMT-8 to the Input of the desired track of the tape
machine.
2) Press PLAY on the MMT-8, then adjust the level of the track so that it reads
approximately "OVU".
3) You must select a tempo for the song on the MMT-8 at this time as it cannot be changed
later.
4) Begin recording on the tape machine.
5) Press PLAY on the MMT-8. Allow the MMT-8 to play through its entire song before
stopping the recording. When the song has ended, stop the recording and rewind the
tape machine. You are now ready to trigger the MMT-8 from the sync tone that you just
recorded.
NOTES;
A) There is no TAPE SYNC OUT switch as this is always active.
B) Keep the Sync signal at about OVU in order to avoid dropouts. If the MMT-8 does not
see the sync tone for 1/2 second, it will assume that the sync tone has ended and will go
into STOP mode.
C) If possible, do not use any noise reduction, EQ, or signal processing on the sync tone.
D) Avoid recording high energy, high-frequency tracks next to the sync track.
TO CLOCK THE MMT-8 FROM TAPE SYNC
1) Connect the output of the track of the tape machine that has the sync tone to the TAPE
IN jack of the MMT-8.
