MOTU MIDI Express XT [71/94] Using other devices as a controller

MIDI MACHINE CONTROL

USING OTHER DEVICES AS A CONTROLLER

We recommend trying to set up MMC as described in “A

recommended setup for MMC” on page 65. However, you

may have an MMC device, such as an MMC-equipped

reel-to-reel tape deck, that does not have the ability to be a

time code slave and therefore needs to be the time code

master. In this case, you need to set up your Express

interface so that it knows that this device will be the master

instead of the computer.

If the device transmits LTC, you can simply connect it to

your Express interface’s SMPTE input and set your Express

interface’s master sync mode to LTC QuikLock.

If the device only transmits MIDI Time Code (MTC),

make the connection shown below in Figure 8-3 and set

your Express interface’s master sync mode to MTC.

Figure 8-3: If you have an MMC device that can only transmit time code (and

cannot be a time code slave), then you can make it the time code master by

routing MTC to your Express interface (MTC In) as shown here. It is better to use

LTC, though, or better yet: your Express interface as the time code master. Both

are a more stable time base than MTC.
