MIDI MACHINE CONTROL

The Alesis LRC (or compatibles)

For details about using an Alesis LRC (Little

Remote Control) or LRC-compatible controller,

see chapter 13, “Alesis LRC” (page 93).

Other MMC transport controllers

MMC transport controllers, such as the JL Cooper

CuePoint™, accomplish what they do with both

MIDI Machine Control data and time code, either

in the form of MIDI Time Code (MTC) or SMPTE

time code (LTC).

As a result, you need to establish bidirectional

MIDI communication between the Digital

Timepiece and the MMC controller (for MMC —

and MTC, if you are using it instead of LTC). This

can be accomplished by connecting the MMC

controller directly to the Digital Timepiece or by

connecting both the Digital Timepiece and the

MMC controller to your multiport MIDI interface

(such as the MIDI Timepiece AV) and routing data

internally between them.

If your MMC controller uses LTC instead of MTC,

you’ll need to route SMPTE to or from the Digital

Timepiece as required by the MMC controller.

For further information about connecting an

MMC controller, see “MMC control surfaces” on

page 30.

Using computer software as an MMC controller

Most likely, you’ll want to set up your computer

software to be an MMC transport master, so you

can control the Digital Timepiece (and everything

slaved to it) from your computer.

This can be accomplished with a MMC-compatible

sequencer, MMC applet, or any other software that

transmits MMC transport control commands.

Generally speaking, once you’ve successfully

established overall MIDI communication between

your software and the Digital Timepiece, all you

have to do is tell your MMC software what the

MMC Device ID is of the Digital Timepiece. From

the factory, the default MMC device ID for the

Digital Timepiece is 1 (in a 1-128 numbering

scheme). If you need to change the Digital

Timepiece’s ID for some reason (most of the time

you shouldn’t need to), you can change it by setting

the “MMC ID” option in ClockWorks’ Sync/MMC

window.

Setting up Performer or Digital Performer as an

MMC controller

For details about using Performer or Digital

Performer as a MMC transport master over the

Digital Timepiece, see chapter 9, “Digital

Timepiece & Performer” (page 67).

MMC CONTROL OF RECORD FUNCTIONS

In addition to transport control, the Digital

Timepiece also supports a wide variety of MMC

record functions. Some are global and others are

device speciﬁc:

Global MMC record functions

The Digital Timepiece supports the following

global MMC record functions:

■ Global record mode (Safe, Rehearse or Record)

■ Record punch-in and punch-out, either manual

or automatic

Global record functions should be sent by your

MMC controller (or software) to the Digital

Timepiece itself, which then passes them on to all

slaved devices. In other words, program your

MMC controller (or software) so that it sends the

global record functions mentioned above to MMC

device ID 1 (or 0 if it uses a 0-127 numbering

scheme), which is the factory default device ID of

the Digital Timepiece (or to another ID that you

have perhaps assigned to the Digital Timepiece

with ClockWorks).
