• Following an MMC-controlled recording, <strong>Logic</strong> <strong>Pro</strong> automatically creates an empty MIDI<br />

region on the tape track. This is to let you know that a recording has taken place on<br />

the tape machine. This applies to all MMC recordings, including those controlled by<br />

the Autopunch function. If you activate several tape tracks (by Shift-clicking), the<br />

corresponding number of regions are created. If a MIDI region with an identical start<br />

point already exists on a tape track, no new MIDI region is created on that track. This<br />

avoids overlapping regions.<br />

• A double stop command sets the project back to the beginning.<br />

The MMC Record buttons also offer you a simple way to arm tracks on your tape machine<br />

with <strong>Logic</strong> <strong>Pro</strong> (see MMC Record Buttons Objects).<br />

You should finish all MMC-controlled recordings with Stop or Space. Some tape machines<br />

react differently to a series of MMC Record commands. Sometimes, this can result in<br />

<strong>Logic</strong> <strong>Pro</strong> showing a track as recording, when the tape is actually playing back (or even<br />

worse, the opposite situation). As such, you should always finish a recording with Stop<br />

or Space, just to be on the safe side.<br />

Synchronization <strong>Pro</strong>blems and Solutions<br />

Given the number of different synchronization types that are available, and different<br />

implementations by various manufacturers, you may occasionally encounter timing issues<br />

when running <strong>Logic</strong> <strong>Pro</strong> synchronously with other devices or applications. This section<br />

will help you to overcome some common synchronization problems.<br />

Faulty Digital Synchronization<br />

If <strong>Logic</strong> <strong>Pro</strong> is synchronized to external Word Clock (Audio Sync Mode: External or Free),<br />

you must ensure that a valid digital signal is always available. If you encounter error<br />

messages such as “Sample Rate xxx kHz recognized” it may be that the DAT recorder (or<br />

whatever clock source you have connected to your audio hardware’s digital input) does<br />

not transmit Word Clock in stop or pause mode (or has switched itself off).<br />

Faulty Synchronization to an External Tape Machine<br />

Create a new project, make a new recording, and see if that does the trick. Why? If an old<br />

recording on tape was not properly synchronized to time code, you won’t be able to use<br />

it. One basic rule: the playback situation must be identical to the recording situation.<br />

If everything is working fine with the new recording, this means the present setup is OK.<br />

Next, check whether anything has changed in your global setup. Has the frame rate<br />

changed? Has the tape speed changed? If you have changed a 30 fps setting, try variations<br />

such as 30 drop or 29.97.<br />
