Version 2.95 GUS fixes June 15th, 1994
New features
- Fixed tremolo effect
- Less UltraClicks
- New DMA loading method for GUS
+ Optional GUS timer based playing (-gt to disable GUS timer)
+ Checks for GUS memory allocation
- Less memory fragmentation -> more free memory in DOS shell
+ Solo track mode (press 'S' to solo/unsolo)
- Fixed panning bug with 16-bit quality mode
- Due to a small bug in the player, retrig, notecut, delaynote
and some other commands were not executed corrected.
- SB/SB Pro and SB16 now use autoinit mode if possible. This
gives better sound quality with less clicks.
- Bugs fixed in S3M loader (vol+tone and vol+vibr were reversed)
- A tiny, tiny bug in 669 loader caused erronous memory allocations..
- SB Pro (and clones) should now play left and right correctly
+ New! Quality mode for 16-bit cards. With the new quality mode
you can get much better dynamics with multi channel modules.
This method uses a 32-bit intermediate mixing buffer and clips
the data into 16-bit output format. Using too high volumes
will cause more clipping which degrades sound quality a bit.
Usage: DMP32 -q -aXXX module
where XXX is the gain (amplification value).
32 = normal volume
64 = 2 x normal volume
100 = 3.125 x normal volume
etc.
Maximum usable amplification is around 700 (which means
2100% amplification, quite loud!)

Version 2.90 Better GUS compatibility May 7th, 1994
Loader fixes
- GUS player now uses PC timer instead of GUS' own timer. This
will cure some problems users have had with DMP.
- Also new technique for GUS DMA download.
+ Better S3M loader.
+ FAR loader can now handle >64 row patterns
- Fixed the SB Pro detection bug
*** ---------------------------------------------------------------------- ***
Version 2.89 New detection routines for SB April 3rd, 1994
Optional DMA for GUS
- New detection routines for SB family. These routines use
the BLASTER environment variable (if available) to detect the
presense of Sound Blaster (Pro, 16). Note that only SB16 can
be detected without BLASTER.
+ You can now use either the old byte-by-byte transfer method or
the new DMA transfer. Parameter '-g' enables the non-DMA
method.
- Fixed a bug in AudioTrix Pro (and Windows Sound System) exit
routine that caused incorrect IRQ and DMA channel to be active
after exit.
- Fixed volume bars.

Version 2.87 First release March 13th, 1994
GUS bug fixes
* First release of 32-bit protected mode version of DMP
* Note that DMP32 doesn't automatically detect any of the SB
family!
- Samples are now downloaded into GUS using DMA
- GUS player bugs fixed (skipped notes, inaccuracy)
- With PAS the DMA transfer was not stopped after exit -> slow down
