Chapter 10 Managing songs This chapter explains song management operations such as saving, loading, deleting, or copying songs. About songs What is a song? Song recording time On the AW2816, musical productions you create are saved on the internal hard disk in units called "songs." A song that you saved can be loaded into internal memory at any time to reproduce the state that was saved. A maximum of 30,000 songs can be saved on the internal hard disk, if capacity allows. However, only the song that is currently loaded (the "current song") can be operated on the AW2816 at any one time. Tip! When the AW2816 is powered-on, the most recently operated song will automatically be loaded as the current song. The time that can be recorded in one song (data area of approximately 6.4 GB) will differ depending on the quantization (number of bits) and sampling frequency of the song. The following table shows the recordable time for each track when a 16-track recording is made using the default song settings. Song Maximum recording time for one track 16 bit/44.1 kHz approximately 1 hour 20 minutes 16 bit/48 kHz approximately 1 hour 13 minutes 24 bit/44.1 kHz approximately 53 minutes 24 bit/48 kHz approximately 49 minutes Songs can be saved only on the current drive. An external drive can be used to back up song data, but cannot be used to save/load the current song or record/playback audio data in the same way as the internal hard disk. Song structure The AW2816 can use a hard disk of up to 64 GB capacity. However, the capacity that can be used by an individual song is limited to 6.4 GB. Of this 6.4 GB, approximately 2 MB is reserved as the system area for storing various non-audio data, and the audio data is recorded in the remaining area (the data area). The diagram below shows the song structure on the hard disk, and the data that is recorded in each area. Please be aware that the data area of a song also contains audio data (i.e., for Undo) that is not actually used in an audio track. For example even when you erase all the audio data after once recording a track, the erased audio data will remain in the song so that Undo can be performed if needed, and this will shorten the available recording time. As necessary, you can execute the Optimize function (¡P.154) which deletes only the Undo data from the song. The table shown above does not include the recording time of the stereo track. • Song (maximum 6.4 GB per song) Internal hard disk (maximum 64 GB/30,000 songs) • System area (fixed at approximately 2 MB) - Settings for each of the TRACK screen pages - Tempo map settings - Scene memories including the current scene - Automix memory including the current automix - Patch libraries - EQ libraries - Dynamics libraries - Channel libraries - Effect libraries - SONG screen/Settings page settings - Settings for each of the REMOTE screen pages • Data area - Audio data for 16 x 8 virtual tracks - Audio data of the stereo track - Audio data for undo/redo Managing songs 10 Operation section 147
