Audio recording
Overview: About the OASYS’ hard disk recorder
• There are sixteen audio tracks. They allow 16-bit
linear PCM recording with a maximum time of 80
minutes.
• Automation data (volume, pan, EQ, send 1/2) can
be recorded for each track.
• Up to sixteen tracks can be played back
simultaneously, and up to four tracks can be
recorded simultaneously.
• The Stereo Pair function lets you assign two tracks
as a pair for recording, control, and editing.
• You can choose from a broad range of internal
buses as the recording source; Audio Input 1–4,
S/P DIF, L/R, REC Bus 1–4, or Indiv 1–8. You can
also route the signal very flexibly, for example by
inserting effects into external audio sources and
recording the result.
• When you realtime-record, an audio event and
region data are created and assigned to the track.
The region data contains a link to the WAVE file
(audio data) that’s recorded on the hard disk. You
can edit in a variety of ways, for example by
changing the location of the audio event, or by
editing/replacing the region data or WAVE file.
• Auto or manual punch-in/out are provided.
• The Rehearsal function lets you practice a punch-
in/out without actually recording.
• You can use the control surface mixer to adjust the
pan and volume etc. of the audio tracks, and record
these operations as automation events so that the
pan and volume changes will be reproduced
during playback.
Audio events and regions in an audio
track
When you record on an audio track, the actual audio
data is recorded directly on the internal hard disk as a
WAVE file. At this time, a “region” is also created; this
contains information specifying what portion of that
WAVE file is to be actually played back. In addition, an
“audio event” which assigns that region is created; this
specifies the location in the song at which the audio
will play.
When playback reaches a point in the song where an
audio event is located, the WAVE file on the hard disk
will be played as specified by the audio event and the
region. In other words, the audio will not play if either
the audio event, the region, or the WAVE file are
missing.
Please note that audio events and regions can be
deleted by audio event editing or region editing,
and can also be easily lost if you turn off the power
before saving to the hard disk. If only the WAVE file
is left on the hard disk, this will occupy hard disk
capacity for no purpose; we recommend that you
execute “Delete Unused WAV Files” (See PG p.523)
to free up any such wasted space.
How audio data is stored on the disk
When you save Songs to disk, they’re stored in an
.SNG file. This .SNG file contains all of the data from
Sequencer mode, including all of the Songs in memory,
except for the related audio files.
