We cannot provide tech support for the general operation of your sampler; however, we do carry the manuals for the ASR-X and ASR-X Pro.


Operating System (O.S.)
The Operating System (O.S.) tells a sampler how to work; it is always a good idea to use the latest version available, as each release fixes bugs and often adds new features. The latest O.S. versions are
2.67 for the ASR-X, and 3.04 for the ASR-X Pro.

To determine which O.S. version is installed in your ASR-X or ASR-X Pro, Press the Disk/Global Save button, and while holding it down, press the System/MIDI button. The display will briefly show which version of the Operating System is currently installed.

The ASR-X and ASR-X Pro use different methods to upgrade the Operating System. The black ASR-X uses EPROM chips (two per set); the O.S. 2.67 chips will upgrade the firmware in the ASR-X to the latest version, which tightens up the timing of the sequencer and allows for the loading of ASR-10 and EPS/EPS-16 Plus samples. The red ASR-X Pro upgrades the O.S. from floppy disk.

Here is what each newer version of the Operating System added:

ASR-X Version 1.10
Allows the ASR-X to import ASR-10 sounds from HD floppy disks.
Kit Mapper provides an easy way to get all the important sounds in a drum kit onto the pads at once.
Auto-normalization can optimize volume of samples as they are created.
Auto-zero cross finder can search waves for best loop positions (at zero crossings).
Each track has a new parameter, TrackMIDIOut, that controls the transmission of data from the track to another MIDI device.
Local Off mode lets the pads, patch select buttons, and foot switch transmit MIDI data without playing the internal sounds.
Track Mix can now record real-time changes.
A new disk file type, ALL-SEQS, allows the saving of all sequencer data to disk at once.
Patch select buttons fully implemented as voice modulators.
Disks are numbered when a file spans more than a single floppy disk.

ASR-X Version 2.00
SCSI is implemented.
Quantization templates are stored in SYSTEMSETUP files.
The first track recorded in a sequence automatically defines the sequence's length.

ASR-X Version 2.50
Quantizing can be done while recording a track.
Pattern mode allows chaining sequences together in real time.
Song mode allows chaining sequences together into a song playlist.
A new SoundFinder category, MIDI-OUT, was added for playing external sounds from the sequencer.
SCSI drives can be copied and optimized.
ASR-10 sounds load faster, and ASR-10, EPS, and EPS-16 Plus sounds can be loaded from double-density (DD) floppy disks.
The global reverb presets selection is improved.
The ASR-X will load .efe and .efa files directly.
The ASR-X will load WAV and AIF files from CD-ROM.
Scale Time parameter will time-stretch or compress sampled loops.
Support of SMDI Sample Transfer Protocol implemented.
Quick-erase feature will delete an unwanted track sound or pad sound.

ASR-X Version 2.67
New Playlist FX Load feature enables much smoother sequence-to-sequence transitions during playback.
Undo works much quicker for sequencer edits.
Handling of Transwaves streamlined.
LFO and MIDI synchronization tightened.
SMDI sample transfers work correctly with Windows 95 and 98.
SCSI saving is quicker.
AIF files load and save quicker.
EPS/ASR-10 instrument translation is greatly improved.

ASR-X Pro Version 3.04
New Playlist FX Load feature enables much smoother sequence-to-sequence transitions during playback.
Sequencer tracks will transmit System Exclusive data for any Ensoniq product.
Current sequencer Loop Playback parameter setting is retained when a song bank is loaded.
Procedure to shorten a sequence is improved.
Undo works much quicker for sequencer edits.
Response to tap tempos is improved.
LFO and MIDI synchronization tightened.
SMDI sample transfers work correctly with Windows 95 and 98.
SCSI saving is quicker.
AIF files load and save quicker.
EPS/ASR-10 instrument translation is greatly improved.

Memory
Both the ASR-X and the ASR-X Pro ship with 2 Meg of memory; the ASR-X has one 72-pin SIMM slot for adding additional sample RAM, and the ASR-X Pro has two 72-pin SIMM slots. A 16-Meg memory kit will boost the sample RAM to 18 Meg, for a total sampling time of 207 seconds (mono). A 32-Meg kit will boost the stock memory to 34 Meg (the maximum for the ASR-X), for a total sampling time of 398 seconds (mono). With the ASR-X Pro, two 32-Meg kits will expand the memory to the maximum 66 Meg, for a total sampling time of 773 seconds (mono). The ASR-X and ASR-X Pro use 72-pin, parity or non-parity, EDO or non-EDO SIMMs.

SCSI and SCSI Drives
Unfortunately, ASR-X SCSI Kits are no longer available. But if yours already has SCSI installed, you should certainly take advantage of it.

Instead of loading and saving sounds to floppy disks, it's a great idea to use an external SCSI drive with your sampler. A SCSI drive will not change the way your sampler works - it won't make better or longer samples - but it will provide enormously faster loading time for sounds, and a very convenient way to store and organize your sounds. Additionally, if you add a SCSI CD-ROM drive, you can purchase sounds on CD-ROM for much cheaper than the same sounds would cost on floppy disks (one CD-ROM holds the equivalent of hundreds of floppy disks worth of data) - though CD-ROMs in ASR-X native format are not readily available. You will have to get sounds in ASR-10 format, then have the ASR-X translate the sounds each time it loads them.

Loading Sounds from Other Samplers
The ASR-X Pro should load and translate sample disks from the Ensoniq ASR-10, EPS, and EPS-16 Plus without any trouble - though frequently patch selects and other programming do not translate perfectly. The ASR-X will translate these sounds as well, but only if you are running the correct Operating System. OS version 1.1 allowed the ASR-X to read ASR-10 HD floppy disks, but not EPS or EPS-16 Plus double-density disks. OS 2.55 or higher enables the ASR-X to read double-density EPS and EPS-16 Plus disks. Syntaur sells the latest OS EPROM chips (version 2.67) for the ASR-X.
