                        REVISION HISTORY OF DMP
                        -----------------------

Version 2.50    Bugfixes                                May 25th, 1993
                EMS support
                Autocalibration
                Utlities are gone

        - some bugs in S3M loader fixed, and no more note shifts!
        - Aria support works now better.
        + DMP can now utilize EMS memory for samples. So you can
          play really large MODs with DMP and still have lots of
          DOS memory! Option -b disables EMS usage.
        + Autocalibration adjusts DMP's sampling rate to match the
          REAL sampling rate of the sound card.
        * GRAB.EXE, VIDEOMEM.COM and batch files for ripping S3Ms
          are now history. If you want them, fetch an older version

*** ---------------------------------------------------------------------- ***

Version 2.46    Bugfixes                                May 18th, 1993
                Aria card support
                Support sites?

        + New Aria-based sound cards are now supported! You can play up
          to 44.1kHz with 16-bit stereo quality!
          If autodetection fails, use -c7 and other parameters...
        - The portamento/vibrato/arpeggio bug in 2.45 fixed.
        - Theoretically speaking, the S3M loader now converts modules
          incorrectly, but in practise they sound a lot better ( a half
          note shift upwards makes wonders.. :)

        * Do you have a BBS and would like to become official support
          site of DMP? Read the included SUPPORT.DMP text file for
          more info.

*** ---------------------------------------------------------------------- ***

Version 2.45    Full panning                            May 14th, 1993
                Monochrome support

        + DMP can now be used with monochrome screens
        + On stereo card, you can now pan any channel to any position.
          You might have to add new channels, if you get cracks. And
          remember that using panning takes about 80% more processor
          power!

*** ---------------------------------------------------------------------- ***

Version 2.44    Bugfixes                                May 12th, 1993
                PC speaker support
                DAC works better with memory managers

        - Corrupted MOD files are now played more correctly. Previously
          the last instrument was not converted into unsigned format.
        + You can now use DMP with PC speaker! Use parameters "-c6 -p42"
          to enable speaker support.
        - DAC (and speaker) work now a lot better with memory managers
          such as QEMM,MAX386 and EMM386.
        - Little bugfixes in S3M loader.

*** ---------------------------------------------------------------------- ***

Version 2.43    Bugfixes                                May 11th, 1993
                Channel panning
                Real volume bars

        - Fixed bugs in 669 and S3M loaders
        + Channels can be panned independently with keys L,M and R. If you
          get cracks in the sound, add more channels with ')'. Select channel
          with up/down arrows. Try panning drums to middle, sounds great!
          Of course, all this works only on stereo cards :-)
        - M2AMF now converts 669 modules correctly.
        + Volume bars are now calculated using the real sample data,
          press 'V' to switch between new/old mode.
        + SB Pro's filter is now off by default -> clearer sound

*** ---------------------------------------------------------------------- ***

Version 2.42    Bugfixes                                May 10th, 1993
                Filter switch for SB Pro
                M2AMF supports 669 and S3M
                Tempo settings

        + Now you can convert your S3M and 669 files into AMF format.
        + If you want to have clearer sound on SB Pro, turn off the
          filter by pressing 'F'
        + You can also change the tempo module is playing by pressing
          [,],{ or } keys. '[]' affect speed, and '{}' affect BPM tempo.
        + Pressing '(' adds and ')' removes one channel. You should clearly
          hear how this affects sound quality.
        - Some bugs fixed in module loaders

*** ---------------------------------------------------------------------- ***

Version 2.41    Bugfixes                                May 9th, 1993
                New utility
                Amplifier

        - Fixed note portamento
        - S3M loader is now a lot more compatible.
        - Some outlook bugs fixed, like help screen and that blinking
          bug after returning from DOS shell.
        * VIDEOMEM is a small utility that transforms 96kB of video
          memory into conventional memory, so you can play bigger
          modules with DMP. Works with other non-graphic software, too.
        + You can now amplify playing with command line switch -a.
          Normal value is 31, but be aware that amplifying may cause
          some nasty cracks if volume goes too high. But amplifying
          is helpful if you're playing 8+ channel MODs on 8-bit cards.

*** ---------------------------------------------------------------------- ***

Version 2.40    Bugfixes                                May 7th, 1993
                Scream Tracker 3.0 support
                Composer 669 support
                New outlook

        - Some bugs with DMA fixed (again :-) )
        + Now you can play S3M modules. Three batch files included
          for easy extraction of modules from Future Crew's demos.
          *NOTE! Not all S3M commands are implemented.
        + You can also play 669 format modules, if they fit into memory :)
        - A small bug in STM loader fixed.
        + Little changes in outlook.. You may have to use 50 line mode
          if you want to see all the instruments in some modules

*** ---------------------------------------------------------------------- ***

Version 2.34    Bugfixes                                April 20th, 1993
                Mailing list

        - Bugs with DMA fixed.
        + DMP now returns an errorlevel of 1 if exited via ESC and
          0 on normal exit (only if looping is disabled).
        * If you want to get new DMP automatically and have Internet
          access, you can join DMP mailing list. Just send a message
          to listserv@oliver.sun.ac.za with following message body

Version 2.33    Bugfixes                                April 14th, 1993

        - A bug in Retrig command (only in 2.32) was fixed
        - Now the 8-channel FastTracker MODs play OK, previously
          there were problems with channels 7 and 8.
        - False Windows detection corrected (occured if you had an
          environment string "WINDIR")
        * And remember: DSMI IS AVAILABLE!

*** ---------------------------------------------------------------------- ***

Version 2.32    Bugfixes                                April 9th, 1993
                New features

        - A bug with Tremor command fixed
        + Now you can disable ProTracker extended tempos for those
          old modules (switch '-e')
        - Some problems with 8-bit DMA in Pro Audio Spectrum 16 fixed

*** ---------------------------------------------------------------------- ***

Version 2.31    Bugfixes                                March 16th, 1993
                New features
                * DSMI IS AVAILABLE *

        - Some bugs with false PAS detections are now fixed
        + You can shell to DOS with Covox, up to 64kHz!!
        * DSMI is finally available! Read the README file for
          additional info...

*** ---------------------------------------------------------------------- ***

Version 2.30    Bugfixes                                March 6th, 1993
                Covox support is back!
                Faster

        - DMP 2.20 failed to load any 15 instrument MODs. Now fixed.
        + Support for Covox. Use parameters '-c6' and '-p' to enable
          Covox (DAC) support at any port address. See revision entry
          for 1.41 for additional info... Covox supports rates up to
          44kHz.
          NOTE: Covox support doesn't work well if you have a memory
          manager like EMM386 or QEMM386 installed.
        + On a 386SX (or other non-cached 386) DMP should be about 10%
          faster :)
        * Thanks for Pieter Immelman for helping out with UNIX
          mail-listserver for DSMI/DMP

*** ---------------------------------------------------------------------- ***

Version 2.20    Bugfixes                                March 4th, 1993
                New features

        - Some internal bugs fixed...
        + Support for 6 and 8 channel FastTracker MODs
        + You can now use an envrionment variable DMP to specify often
          used command line arguments, for example:
          SET DMP=-s30 -m -o
        + Volume can be changed with + and -
        - UMB support is gone :-( Use PMP (Protected Module Player) to
          play REALLY large modules
        * Changed the method for detecting Pro Audio Spectrum cards.
          Please test on PAS and PAS+

*** ---------------------------------------------------------------------- ***

Version 2.11    MOD loader bugfix                       February 22nd, 1993

        - Some MODs used highly NON-STANDARD period values, so the
          change I made in version 2.02 caused erranous loading. Now
          the loader should handle any MOD.

*** ---------------------------------------------------------------------- ***

Version 2.10    ProTracker tempo support                February 21st, 1993

        + Support for ProTracker's extended tempos has been added.
          Both regular and ProTracker-tempo (in BPM) are now shown on
          screen.
        - Some minor bugfixes.

*** ---------------------------------------------------------------------- ***

Version 2.02    Bugfixes                                February 15th, 1993

        - Bug in the MOD loader caused erranous volumes when instrument
          changed.
        - When using a 16-bit soundcard, DMP could cause machine lock-up
          if a 386-program was run in DOS shell. Now it won't.
        - Help screen showed wrong information about '-u' switch

*** ---------------------------------------------------------------------- ***

Version 2.01    UMB support defaults to DISABLED        February 9th, 1993
                Bugfix

        - Because of the many reports of memory problems with UMB
          options, it now is disabled by default.
          Use '-u' to ENABLE it, previously that switch DISABLED it!
        - Pausing module with 'P' caused computer to lock up with
          a SB Pro. Now it's fixed.

*** ---------------------------------------------------------------------- ***

Version 2.0     DMPMT and DMP combined into one .EXE    February 7th, 1993

        * DMPMT no longer exist as a separate executable as it's
          functionality has been embedded into DMP.EXE. DMP now
          automatically detects DesqView and Windows and changes
          to DMPMT mode if either is detected. You can also force
          DMPMT mode with '-t' parameter which also accepts
          buffer size like '-t30000'.

*** ---------------------------------------------------------------------- ***

Version 1.95    UMB support                             February 6th, 1993

        + DMP fully utilizes all available upper memory. Now you have
          more memory available in DOS shell and you can also load
          bigger modules.

*** ---------------------------------------------------------------------- ***

Version 1.91á   MOD loader bug fix                      February 5th, 1993

        - A bug in the module loader, caused infinite loops if trying
          to load a corrupted module. Now DMP prompts wheather or not
          to play the module.

*** ---------------------------------------------------------------------- ***

Version 1.90á   Support for SB16, PAS+ and PAS16        February 3rd, 1993
                Many bugs fixed
                386 support

        + 386 instruction set is now fully utilized. Which means that DMP
          won't run on a 286 anymore.
        + DMP is now the only module player capable of playing modules
          with 16-bit accuracy. On a SB16 or PAS16 DMP uses a new mixing
          routine that calculates at 16 bits. This gives you a lot clearer
          sound. Also a new mode, Quality mode, is introduced for 8-bit
          cards.
        + DMP is now a lot faster...
        - Numerous bugs were fixed. Can't remember what bugs, though. :-)
        - Support for DACs is removed, because of non-functionality.
        - No more blue backgrounds after exiting (this wasn't a bug, but
          some people didn't like it...)
        ! Special thanks to Pirkka Palosaari for lending his SB16 ASP.

*** ---------------------------------------------------------------------- ***

Version 1.41    DAC support                             December 2nd, 1992

        + Added support for general DACs. Try port value 378 (LPT1)
          If you want to have fun, use port values 3C9,3C0,3C2,61
          (BTW, it took about two hours to add support for DACs... :-)

*** ---------------------------------------------------------------------- ***

Version 1.4     8-channel support                       December 2nd, 1992

        + StarTrekker 8-channel MODs are now supported. If you have
          information about other 8+ channel formats, please send it to me.
        + Some internal changes to ease the way to Covox support in upcoming
          versions...

*** ---------------------------------------------------------------------- ***

Version 1.35    New features                            November 26th, 1992
                Bug fixes

        - Improved compatibility with MODs.
        + Now you can go backwards and forwards in the module.
        + New commandline option to supress modules looping. Great for
          BATs.

*** ---------------------------------------------------------------------- ***

Version 1.34    Bug fixes                               November 23rd, 1992

        - Fixed a bug in arpeggio command
        - There was a serious bug with SB Pro when playing at >20KHz
          (only in version 1.32 & 1.33). Now fixed.

*** ---------------------------------------------------------------------- ***

Version 1.33    Bug fixes                               November 16th, 1992

        - Fixed the fine tune. Old versions played worse than versions
          without fine tune! Remember to reconvert AMF modules with invalid
          fine tunes.
        - Also fixed a bug in portamento command.

*** ---------------------------------------------------------------------- ***

Version 1.32    Faster!                                 November 15th, 1992
                New feature

        + DMP is now faster than ever... just believe me!
        + I've added "the-most-wanted-feature": pattern jump!!!
          Just press B to break to next pattern...
        - I might have fixed some bugs too, don't know for sure though....

*** ---------------------------------------------------------------------- ***

Version 1.31    Bug fixes                               November 2nd, 1992

        - Fixed a bug in AMF converter/loader. DELETE YOUR OLD AMF FILES!!!
        - Some incompatibles in MOD loader fixed.

*** ---------------------------------------------------------------------- ***

Version 1.3     Enhancements                            October 21st, 1992
                Bug fix
                New file format AMF

        + Support for more octaves (0-4) in MODs, because some PC MOD-editors
          (notably ModEd) support these octaves.
        + Now DMP also loads StarTrecker modules
        + DMP now supports AMF modules and includes a program to convert
          STM or MOD formats into AMF.
        * You can reach me through the Internet! Address is:
          c142092@cc.tut.fi
        - Fixed a memory trashing bug

*** ---------------------------------------------------------------------- ***

Version 1.24    Bug fixes                               October 14th, 1992

        - There was a killer bug that prevented SB Pro mode from functioning
          correctly. Now SB Pro owners can find a big improvement in sound
          quality!

*** ---------------------------------------------------------------------- ***

Version 1.23    New features                            October 4th, 1992

        + The playing order of modules can now be scrambled with commandline
          option '/O'.

*** ---------------------------------------------------------------------- ***

Version 1.22    Bug fix                                 October 3rd, 1992

        - Now DMP shows the real sample rate which may differ from
          what user required, but only a little :-)

*** ---------------------------------------------------------------------- ***

Version 1.21    Bug fix                                 September 29th, 1992

        - A bug in tempo command made some modules play REAL SLOW!
          I hope I have now fixed it.
        + I forgot to change the version number in 1.2 :-)

*** ---------------------------------------------------------------------- ***

Version 1.2     New player for DesqView                 September 28th, 1992

        + A player especially designed for DesqView is now included.
          Its name is DMPMT (DMP for MultiTaskers)
        - There was a bug in the DMA routine.. Only in the 1.12 version. Fixed

*** ---------------------------------------------------------------------- ***

Version 1.12    Internal Changes                        September 28th, 1992
                Bugfixes

        + All sound output handling goes through SDI now,
          (SDI = Sound Device Interface) which allows me to add support
          for new sound cards easily by writing a new SDI!!
        - There was a killer bug in the buffer calculation routine, but
          it only occured under very specific conditions. Finally fixed!

*** ---------------------------------------------------------------------- ***

Version 1.11    Bug fixes                               September 27th, 1992

        - Pressing F10 changed volume to 57 not 64 as I intended. Fixed.

*** ---------------------------------------------------------------------- ***

Version 1.1     New features                            September 26th, 1992
                Bugfixes

        + Function keys F1 - F10 change the overall volume.
        + SB Pro mixer's status is restored before exiting.
        + New command line option "/C" allows SB Pro users to play modules
          in SB (mono) mode.
        - Retrig command with value of 0 caused a division error. Fixed.
        - Now volumes greater than 64 are converted to 64.

                Bugfixes

        - STMs and MODs are now played exactly the same, so
          original Scream Tracker modules play a little bit too
          fast.
        + Instrument list!
        + Better DesqView compatibility (DMP asks DV for screen address)

*** ---------------------------------------------------------------------- ***

Version 1.06    Bugfixes                                August 31st, 1992

        - MOD files are now played at the right speed and frequency

                Bugfixes

        - when a fatal disk error occured, the error message
          was shown off-screen. Now it shows on the screen.
        + Following module commands are now supported:
                Set sample offset       (0x9)
                Fine volume             (0xEA,0xEB)
                Fine portamento         (0xE1,0xE2)

Version 1.01    Bugfixes                                August 17th, 1992

        - corrected the bug in the file search routine, DMP will not try
          to load a non-existent module anymore!
        - a bug in the volume table caused cracks in voice. Corrected.
        + DMA-buffer's size reduced to 1024 (2048 before) so that
          notes on-screen would better match the playing voice.
