Note: You can choose to bounce, rather than copy and convert your audio files from 24
to 16 bit. The advantage of this approach is that the POW-r dithering algorithms can be
used to improve the quality of the downsampled audio data.
Sample Editor
All functions of the Sample Editor can be used on 24 bit audio files. You can even
exchange sound material in either direction (between 16 and 24 bit files) when using
DTDM, via the Copy and Paste commands.
Note: Premiere plug-ins are not supported in Mac OS X. AudioSuite plug-ins are
supported at 16 and 24 Bit depth, if using DAE.
Simultaneous Operation of TDM and Other Hardware
Please note the following if you wish to use a TDM system and other audio hardware
simultaneously:
Generate Audio Mixer
The easiest way to generate the desired Audio Mixers, would be to run the Logic Setup
Assistant again. This is done by choosing Logic > Preferences > Start Logic Setup
Assistant.
If you have set up your TDM hardware correctly, you can also generate a TDM Mixer in
the Environment automatically.
To do so, follow these steps:
m Open a completely new song with standard defaults (a default song) by pressing
Option-Command-N ( you can also choose the File > New menu option while holding
Option).
Dependent on the connected hardware, this song will include Audio Objects that
correspond to the currently active audio hardware, in the Audio layer of the
Environment.
Note: If DAE and DTDM, or DAE and Core Audio are activated, only TDM Audio Objects
will be generated.
Control Playback
To control playback in the Audio window or in the Sample Editor, select the desired
hardware unit and channel, via Channel and Device (at the left side of the window).
