ALESIS HD24 Details
The HD24 provides 24 tracks of high-resolution 24-bit recording at standard sample rates of 44.1kHz, 48 kHz, or at 88.2kHz and 96kHz with a forthcoming 96 kHz I/O option. External word clock input is provided for slaving to external clock sources.
The Alesis HD24 provides the ability to cut, copy, paste,
insert and move tracks and segments of audio with undo function . These functions
can be controlled from the HD 24 front panel, or optional remote control. Recognizing
that a broad range of affordable computer-based editing solutions are already
in the market, Alesis provides multiple ways to export audio for additional
processing and graphic editing. Rear panel Ethernet connection makes HD24 files
accessible to computers in industry-standard WAV and AIFF format. Additionally,
the HD24's 24-bit ADAT optical I/O allow simultaneous transfer of 24-track
material in real time to computer audio cards and other products using ADAT
optical format.
The ADAT HD24 24 can be controlled via supplied LRC remote control, and MIDI
machine control . Control of transport, track arming and editing functions will
be possible via optional full-function remote control. The Alesis HD
24 supports
MIDI commands and sys-ex bulk dumps via MIDI In/Out connectors and has Midi Timecode
out. Includes (2) hot swappable drive caddies- one with removable 40 gig IDE
drive
Understanding the Importance of the DM24 Linear Recording
All other hard disk recording systems use a 'random' access file system to store the audio so you can arrange the regions wherever you and the computer want it which is known to cause software errors that corrupts the exact timing relationship between tracks.
The DM24 hard disk is formatted with a proprietary system that makes it work just like tape. All of the space on the hard disk is allotted to audio ahead of time. If you have inserted a 60-minute disk, it will record 60 minutes of audio on 24 tracks, but it also will only record 60 minutes of audio if you're only using four tracks — just like a piece of tape. If you make an edit to the song, it works just like cutting the tape with a razor blade; that segment is skipped over during playback.
The tracks can't slip in time like they can with a normal hard disk recording system. Hard disk stability has now come of age can now actually replace tape!
The first hard disk recorders worthy of the name ADAT....
Introducing the world’s first 24-track, 24-bit/96kHz hard disk recorders designed to fit comfortably into any standard ADAT environment — and match ADAT’s legendary performance and affordability.
With their patent-pending method of writing to the hard drive, HD24 and HD24XR are the first hard disk recorders built from the ground up exclusively for the purpose of recording music instead of data — resulting in remarkable stability and performance. And yet, thanks to their use of standard, low-cost IDE computer drives, the recording media costs no more than traditional ADAT tape on a per track basis.
Two hot-swappable media bays provide convenient access to the recording drives, and allow the user to backup data in just minutes. You can edit tracks internally or easily transfer to computer via built-in Ethernet. They’re the only HD recorders on the market with standard ADAT Optical and ADAT Sync, enabling them to work efficiently with existing systems. And they offer the same exceptional user-friendly interface ADAT users have come to expect.
Alesis reinvents digital recording. Again.

ADAT-HD24 Firmware v1.18
This is version 1.18 of the ADAT-HD24 Firmware. This release adds additional support for manufacuring. This release also fixes a bug where pressing [STOP] in between punch points from a master sync device while auto-recording would cause the next PLAY command to re-enter auto-recording mode on the slave HD24s, rather than play mode.
It also fixes a second bug where record-enabling a track (where previously no tracks were recordenabled) after [RECORD] was pressed from the master sync device while in autorecord mode would cause the slave HD24s to not actually record audio even though its record LEDs are steady Specific information for this release can be reviewed in the Release Notes.
