Audio Cycle Recording
You can make audio recordings even when “Cycle” is switched on. A new track is
created for every cycle repeat. All newly-created tracks are played by the same Audio
Object. This prevents the different “takes” from being played simultaneously.
If you stop recording just after a full cycle has ended, no new Region is created for the
cycle that has just begun. The audio material is not lost, but is recorded after the last
Region in the audio file.
The whole recording (all cycle repeats) is stored as a single audio file. This audio file is
split into Regions, each as long as the Cycle length. The Region of the preceding cycle
is automatically muted when playback of the ensuing cycle/Region begins.
Audio cycle recording also works when you’re simultaneously recording two channels
(stereo tracks in split stereo mode, for example).
After recording, please note …
After you’ve made your first audio recording in a song, you should not make any
further adjustments to the tempo of the song. Decide on a tempo, and any changes in
tempo, well before the first audio recording, and stick to it. Audio recordings have a
fixed playback rate, and can only be matched to new tempos if you’re prepared to go
through a great deal of hassle.
The time compression/expansion algorithms available in Logic only permit you to
match audio to new tempos when the tempo differences involved are relatively small;
if you try and use them to significantly change the tempo of your recordings, audio
quality may be significantly compromised.
Note: You can, of course, change your audio recordings into Apple Loop format files.
This file type makes transpositions and time stretching tasks much easier (see “Apple
Loops” on page 72).
If you’ve made your audio recordings in real time, playing them over the top of an
existing MIDI arrangement, it is not particularly recommended that you move the
Anchor of any of your Regions. You can make slight adjustments to the timing of your
Regions using the Delay parameter.
Auto Input Monitoring
Input monitoring allows you to determine what signal is heard on record-enabled
tracks. If Auto Input Monitoring is switched on, you will only hear the input signal
during the actual recording—before and afterwards, you’ll hear the previously
recorded audio on the track, while the sequencer is running. This helps you judge drop-
in and drop-out points for punch recording. If Auto Input Monitoring is switched off,
you will always hear the input signal. Auto Input Monitoring, when switched on, also
allows you to hear the input source when Logic is stopped, making it easy to set levels.
