About Audio Tracks
Methods of Recording Audio Tracks
RAMTracks — Record directly into internal memory. No additional hardware is required (16 Meg
RAM is recommended — record up to three minutes mono @44.1 kHz, 4.5 minutes mono @29.76
kHz with 16 Meg RAM). RAMTrack data is stored entirely in the SONG + ALL SEQS file type.
Internal RAM Memory
Audio Track data is stored in:
Audio Input
OR
ASR-10
DiskTracks — Record directly to a SCSI storage device (hard disk, removable media, etc.) via the
SCSI Interface (SP-3 option required for the keyboard version ASR-10). DiskTracks will work on a
standard ASR-10, although expanded RAM is recommended. Recording time is limited only by
the size of the SCSI storage device (as a general rule, 10 Meg = about one minute of stereo
recording @44.1 kHz).

For more information about using SCSI with your ASR-10, including optional connector setups,
refer to the SP-3 SCSI Manual.
Audio Track Polyphony
Each Audio Track can use up to two voices of polyphony: Source monitoring requires one voice,
and playback requires another voice. You can recover two of these voices, turn the source
monitor off (red Source-Monitor LED unlit), and/or mute Audio Track playback on the
Edit/(audio) Track, ATRK PLAYBK STATUS page.
Types of Audio Tracks
The ASR-10 can record and play back two different types of Audio Tracks: sequence audio tracks
or song audio tracks.
Sequence Audio Tracks
An ASR-10 sequence is a collection of eight independent Instrument tracks and their associated
notes and controller data. Each sequence has its own pair of Audio Tracks, containing audio
trigger events that trigger a collection of AudioSamples from RAM or SCSI.
