MIDI MACHINE CONTROL

SETTING MMC DEVICE ID’S

Each MMC device requires a unique MMC device ID,

including your Express interface itself. The factory default

ID of your Express interface is 19. If needed, you can

change it as shown in Figure 5-8 on page 41.

SETTING UP OTHER MMC DEVICES

If you have an MMC-compatible device, you can slave it to

your Express interface. But ﬁrst, you need to make your

Express interface send MTC (or LTC for some devices). To

send MTC, use the Routings tab in ClockWorks to make

connections from the MTC Out port in the left-hand

column to the desired destinations in the right-hand

column as demonstrated in Figure 7-1 on page 56.

For most MMC devices that support being an MMC slave,

routing time code (either MTC as just discussed or LTC)

to them is all you need to do. For some devices, you may

also need to get your Express interface to send MMC

transport commands to the device. Once again, you do

this in the Routings tab: connect the MMC Out port in the

left-hand column to the destinations in the right-hand

column as demonstrated in Figure 7-1 on page 56. Then

you are ready to control your MMC device — via your

Express interface — from the computer (or a hardware

MMC controller).

PREPARING SOFTWARE FOR MMC

Regardless of what you decide to use as your MMC

transport control master (an MMC controller device or

computer software), you need to set up the software so

that it will slave to MIDI Time Code (MTC) generated by

your Express interface. This will ensure that your software

chases and locks with all other MMC devices. Check to

make your software is set up to the proper frame rate, and

that it is in “external sync” or “slave” mode, waiting for

MTC.

USING SOFTWARE AS AN MMC CONTROLLER

Most likely, you’ll want to establish your computer

software as the MMC transport control master, so you can

control all MMC devices from your computer, allowing

you to play, stop, and cue all connected devices directly

from your software’s main transport controls.
