-
- SoftOSS is a software based wave table emulation which works with
- any 16 bit stereo sound card. Due to its nature a fast CPU is
- required (P133 is minimum). Although SoftOSS does _not_ use MMX
- instructions it has proven out that recent processors (which appear
- to have MMX) perform significantly better with SoftOSS than earlier
- ones. For example a P166MMX beats a PPro200. SoftOSS should not be used
- on 486 or 386 machines.
-
- The amount of CPU load caused by SoftOSS can be controlled by
- selecting the CONFIG_SOFTOSS_RATE and CONFIG_SOFTOSS_VOICES
- parameters properly (they will be prompted by make config). It's
- recommended to set CONFIG_SOFTOSS_VOICES to 32. If you have a
- P166MMX or faster (PPro200 is not faster) you can set
- CONFIG_SOFTOSS_RATE to 44100 (kHz). However with slower systems it
- recommended to use sampling rates around 22050 or even 16000 kHz.
- Selecting too high values for these parameters may hang your
- system when playing MIDI files with hight degree of polyphony
- (number of concurrently playing notes). It's also possible to
- decrease CONFIG_SOFTOSS_VOICES. This makes it possible to use
- higher sampling rates. However using fewer voices decreases
- playback quality more than decreasing the sampling rate.
-
- SoftOSS keeps the samples loaded on the system's RAM so much RAM is
- required. SoftOSS should never be used on machines with less than 16 MB
- of RAM since this is potentially dangerous (you may accidentally run out
- of memory which probably crashes the machine).
-
- SoftOSS implements the wave table API originally designed for GUS. For
- this reason all applications designed for GUS should work (at least
- after minor modifications). For example gmod/xgmod and playmidi -g are
- known to work.
-
- To work SoftOSS will require GUS compatible
- patch files to be installed on the system (in /dos/ultrasnd/midi). You
- can use the public domain MIDIA patchset available from several ftp
- sites.

- *********************************************************************
- IMPORTANT NOTICE! The original patch set distributed with the Gravis
- Ultrasound card is not in public domain (even though it's available from
- some FTP sites). You should contact Voice Crystal (www.voicecrystal.com)
- if you like to use these patches with SoftOSS included in OSS/Free.
