Operation

Playing Audio

Press the PLAY key and audio at the current location on the timeline is played back. The HD-P2’s play- back engine is based on a 24 hour day and will play audio from time 00:00:00.00 to 23:59:59.59. If time- code mode is not enabled, the HD-P2 will stop when it reaches the end of day (during play or while fast forwarding). It also stops if you are rewinding and hit the beginning of the day. See the Timecode section for specific information on its behaviors and settings.

To locate to the beginning of recorded audio, hold STOP and press REW. Hold STOP and press FFWD to go to the end of all recorded audio. The LOCATE Ô/ keys, by default, locate to previous or next markers and file start points. For example, after recording is stopped you can press the LOCATE Ôkey to go to the beginning of the recorded file (assuming no markers were dropped) and then hit play to review it.

HD-P2 Playback Considerations

The HD-P2 playback engine maintains an internal, dynamic edit decision list (EDL) to determine what

files are played and when. In default auto-append mode (no pre-record) each file abuts the previous file.

Figure 6 – Auto-Append Recording

When auto-append is off (or when chasing timecode) you can locate the timeline to any point in the 24 hour day and start recording, even if there is audio already recorded at that time.

The HD-P2 always records non-destructively, which means previously recorded files are not modified, requiring the playback engine to know which file to play back when it reaches that point on the timeline.

The rules for the internal EDL are quite simple: files are ordered by timestamp and creation time. If two files span the same period on the timeline, the most recently recorded file will be played back.

For example these files show the time of day that they were recorded. The place along the timeline indicates where in time (samples from zero) they were recorded.

Figure 7 - Logical Audio Timeline

When played back the most recently recorded (time of day 9:02) file is given precedence and played instead

of the portions of the first two files recorded at 9:00 and 9:01.

If the 9:02 file is moved to the trash, then the underly- ing portions of the other two files will play back once again.

Unless the files need to be located at a specific time on

the timeline it may be easier to keep the auto-append option on to avoid confusion. When in doubt you can visit the Project Files menu and audition individual files in their entirety.

Media Space and Recording

While recording, the media space icon and text in the lower right of the screen change to reflect how much space is left. Should the media approach becoming too full, a low level warning is displayed. If recording continues, the HD-P2 will eventually run out of space, automatically stop recording, close the file, and dis- play an out of space message.

NOTE

The FAT file system only supports file sizes up to 2 GB. The HD-P2 will recognize if a file is reaching this limit, close the file, and start a new file without interrupting the recording. The files themselves will abut within your DAW seamlessly.
