Soflware Notes
Sample playback “skipping” occurs when playing back RAMTRACK audiosamples or regular wavesamples which
are greater than 2M samples at 3OKHz. This problem can occur on any unit which has
SM
or
10M
or ram. All other
memory configurations work fine. The skipping usually starts at 43 seconds into the sample. The result is that the system will
play random chunks of its sound ram (including the Operating System space which sounds like bursts of noise). Fixed.
GENERAL / SYSTEM
ASR could have intermittent problems during song record or playback if the display is on the sequencer locate page.
This was a low-level error related to the display updating the current position in the song (error did not occur unless you were
on the locate page). This was a nasty problem that could be responsible for random crashes that occur during or after
sequence record or playback. For example, the “Gift of Gab” demo always crashed with an error 129 or 135. Any song file
could exhibit a problem. It all depends on the content of the song file. Fixed.
ENHANCEMENT ADDED:
The saving of SONG AND ALL SEQS is faster. Intelligence has been added to the SAVE SONG AND ALL SEQS
command to optimize the project file save time. Depending on the circumstances prior to the save, the time spent shuffling
data should be reduced by as much as 40%.
ASR-10 Version 3.00 Release Notes
The ASR-10 Version 3.00 Operating System (DISK only) has been tested and is ready for release to production. All ASR-IO
models (keyboard, rack, and keyboard with SCSI) will be getting this O.S. (p/n 8530000112) as a running change. The
EPROM update kit, which is included in the SP-3 and DI-10 service kits, will also pick up this change. For customer service
updates, the O.S. Disk requires version 1.50 ROMs. Any customer who is receiving this as a free upgrade should also receive
the new manual “Version 3 Operating System” (p/n 93 11006301). This manual now contains the operating instructions for
the SCSI interface and the DI- 10.
Note regarding Operating System size.
To support the
new
features added by this release, the Operating System has grown. You will see that the O.S. is 160 blocks
larger than our previous release, Ver 2.5 1. This means that with the Version 3.00 O.S.:
l On
bootup,
the FREE SYSTEM BLOCKS field will display a smaller number than Version 2.51.
l Banks that were within 160 blocks of the end of memory with Version 2.5 1 will no longer completely fit with
Version 3.00.
l Instruments that were within 160 blocks of the end of memory with Version 2.5 1 will no longer completely fit with
Version 3.00.
l Project files that were within 160 blocks of the end of memory with Version 2.5 1 will no longer completely frt with
Version 3.00.
l Rewriting the new O.S. to a disk that containing Version 2.51 will result in NOT ENOUGH DISK SPACE if the disk
did not have 160 blocks free.
The ASR-10 has gone though some major changes since it’s initial release. RamTrack and DiskTrack Recording (Version
2.0) DAT Backup (Version 2.5), and Importing Instruments from
AKAI
and Roland Libraries (Version 3.0). As we continue
to support the ASR- 10 by adding features, the Operating System must grow to
accomodate
the new software. This is the
tradeoff that must be paid. Note, however, that the Version 3.00 Operating System is compatable with the current Ver 1.50
ROMs. So a ROM upgrade is not required (assuming the unit is already running Operating System 1.50 or higher.)
New Feature: Auto Configure of
DiskTracks
The ASR-10 can now remember the Audio Track Configuration parameters when the unit is configured for DiskTrack
Recording. These parameters can be saved with Global Parameters. On the subsequent booting of the ASR-10, the unit will
prompt you to “CONFIGURE SCSI ATRKS?“. Hitting ENTER at this point will automatically configure the ASR-10 for
DiskTrack recording with your saved parameters.
See the Version 3 Operating System manual for details.
New Feature: Auto Prepare of Song Files
The ASR-IO will now automatically prepare the audio tracks for the song whenever a song file is loaded. On completion of
the song file load, the display will briefly show “PREPARING AUDIO TRACKS”. Note that song files that do not use audio
tracks will still briefly show this message while the song file is being scanned for audio track data. See the Version 3
Operating System manual for details.
