MMC
MMC (MIDI Machine Control) is a specification that allows MIDI messages to be used to control devices such as tape recorders, VTR's, and digital recording systems.
Thirty-seven MMC commands are available, including Stop and Play.
MMC Mode MASTER,
SLAVE
MMC Output OFF, ON
MTC
MTC Sync Output OFF, ON
MTC Frame Rate 24, 25, 29N,
29D, 30
MTC Offset Time Hour 0–23 (hours)
MTC Offset Time Minute 0–59 (minutes)
MTC Offset Time Second 0–59 (seconds)
MTC Offset Time Frame 0–29 (frames)
MTC Error Level 0–10
MIDI Clock and MTC
MIDI Clock and MTC (MIDI Time Code) are both messages used for synchronization. Select either of them depending on the application.
MIDI Clock transmits and synchronizes operations to a song recorder's performance tempo, whereas MTC synchronizes operations between
devices based on an absolute time. Since Roland VS Series workstations are hard disk recorders, they cannot send MIDI Clock. Therefore,
using a MTC is convenient for synchronization of the hard disk recorder and the JUNO-G. However, VS Series devices also feature
specialized tracks for recording MIDI Clock, so with the JUNO-G's MIDI Clock recorded in this manner, we have another synchronizing
technique in which the VS device appears to be sending MIDI Clock (although it is actually playing back tracks to which MIDI Clock has
been recorded). However, since the tempo must be recorded to the VS sync track beforehand, MTC is only convenient in synchronizing with
songs that do not contain great amounts of tempo data.
Settings Common to All Modes (System Function)
Explanation
Specifies whether Program Change messages will be transmitted (ON) or not (OFF).
Specifies whether Bank Select messages will be transmitted (ON) or not (OFF).
Specifies whether Active Sensing messages will be transmitted (ON) or not (OFF).
Specify whether changes you make in the settings of a patch, performance will be transmitted as system exclusive mes-
sages (ON), or will not be transmitted (OFF).
Thru function re-transmits all messages received at the MIDI IN connector to the MIDI OUT connector without modi-
fying them in any way.
Explanation
Specifies whether Program Change messages will be received (ON) or not (OFF).
Specifies whether Bank Select messages will be received (ON) or not (OFF).
Specifies whether System Exclusive messages will be received (ON) or not (OFF).
Specifies whether General MIDI System On messages will be received (ON) or not (OFF).
Specifies whether General MIDI 2 System On messages will be received (ON) or not (OFF).
Specifies whether GS Reset messages will be received (ON) or not (OFF).
Explanation
When synchronizing the JUNO-G with a hard disk recorder, such as one from the Roland VS series, specify which
synchronization signal the JUNO-G's song recorder will use for operation.
MASTER: The JUNO-G will be the master. Use this setting when you want other devices to follow the operation
of the JUNO-G.
SLAVE: The JUNO-G will be the slave. Use this setting when you want the JUNO-G to receive MMC (MIDI Ma-
chine Control) from an external device and operate accordingly.
Turn this "ON" if you want to synchronize with a hard disk recorder, such as one from the Roland VS series.
When set "ON," MMC (MIDI Machine Control) related commands (Play, Stop and Locate) will be transmitted.
Set this parameter "ON" when you want MTC (MIDI Time Code) to be transmitted to an external MIDI device. If
not, set it "OFF."
MTC frame rate
Make sure that the same mode is set in both master and slave devices.
24: 24 frames per second
25: 25 frames per second
29N: 29 frames per second, non-drop format
29D: 29 frames per second, drop format
30: 30 frames per second, non-drop format
* When synchronizing with a hard disk recorder such as the Roland VS series, any frame rate is all right—as long as the setting
matches that of the JUNO-G. However, when synchronizing operation with video devices such as video decks, the video de-
vice's frame rate is fixed, so the JUNO-G's setting must correspond to that frame rate.
Coordinates the playback timing of the JUNO-G and the external device in an hour units.
Coordinates the playback timing of the JUNO-G and the external device in a minute units.
Coordinates the playback timing of the JUNO-G and the external device in a second units.
Coordinates the playback timing of the JUNO-G and the external device in a frame units.
Determines how often the reception status is checked when MTC is being received from an external device. Stop syn-
chronization if a problem becomes apparent with the check.
The checking interval will be longer for larger values.
In strict terms, the lower the numerical value set, the more accurate the check is. However, playback may be
stopped overly frequently if too rigorous a check is made, and this soon becomes inconvenient. By raising the Er-
ror Level setting, then even if problems with the reception of MTC do occur, synchronization can then continue
as long as such problems remain at a level that does not cause undue problems.
