Akai DPS12 Frequently Asked Questions

Operating System Versions

 Operating System Versions

1.0 First public release. Not many DPS12's were shipped with this.
1.0a Most of the first batch of DPS12's were shipped with this version. There are some drive handling problems with this version, so if you have this or earlier versions of the OS, you should consider upgrading as essential, before you lose something important!
1.1 First upgrade available from Akai. Added extra bus, master out level, some improved locate functions, improved drive handling, improved align function, a few shortcuts to the control panel, and some other miscellaneous bugfixes.
2.0 Added CD-R/CD-RW support, both backup and audio CD creation, timestretch and stretch-insert edit commands, improved backup handling (support for multiple backups on one disk), four new reverb algorithms (only with FX board included)
2.10 Added SysEx support (for the forthcoming MESA), bugfix for punch-out glitches, bugfix for adjusting edit points in bar.beat.clock mode.
2.11 Bugfix release. Fixes for minor bugs that in some circumstances could cause a "system lock", and a bug when reloading multiple disk backups to a disk with not enough free space is fixed.

 Future Versions

I don't have any further infomation about future DPS12 plans. I would hope to get some new features and this may well happen, although Akai's effort will probably mostly be focussed on the DPS16 for a while. This could be a good thing though, as new features for the DPS16 could well filter down into the DPS12, as much of the two machines' core operating system is very similar.

 How do I find out what version I have?

The version number is displayed onscreen when the DPS12 powers up. In addition, with V2.0 and above, pressing the "INFORM" key on the DISK page when the cursor is on SCSI ID:6 (or whichever ID your DPS is set to), the version number is also displayed.

 Can I read project data backed up with early OS versions after I upgrade?

Yes, you should be able to. Certainly there are no problems with DAT backups - I can successfully read 1.0a DAT backups with V2.0. However, some people have reported difficulties in reading backups made to both SCSI devices and DAT. Without further information it's impossible to say whether this is a bug in the OS or whether those particular backups were corupted for some other reason.
