SimSynth copyright(c) 1995 by David Billen.

This is the README file for SimSynth. For a general introduction,
see the INTRO.WRI file. For technical reference, see the help
file which is accessible from within the program. If you do not
know how to program a synthesizer, and would like to learn, see the
HOWTO.WRI file...


===== WHAT IS SIMSYNTH?
SimSynth is a sound synthesizer. It allows you to create new sounds.
SimSynth does for sound what a paint program does for graphics.
SimSynth generates RIFF wave format files, (.WAV files), which can
be played from a Windows compatible wave device, or converted
for use in DOS applications.


===== HOW TO INSTALL
Simply copy the contents of the installation disk to a sub-directory.
Your system configuration does not need to be modified!


===== SYSTEM REQUIREMENTS
Minimum:
  - Microsoft Windows version 3.1 or above
  - 80386 (or better) processor
  - 4+ megabytes of RAM
  - Math co-processor
  - Sound card

Recommended:
  - 80486 50mhz (or better) processor
  - 8 megabytes of RAM
  - Stereo sound card


===== CHANGES FROM VERSION 1.2 TO VERSION 1.3
- You can now specify a .SYN file as a command line argument to
  SimSynth. This means that you can also associate the extent .SYN
  with SIMSYNTH.EXE from the File Manager.

- LFO as noise, with a negative frequency, no longer causes a crash.

- +1 and +2 in the OSC section no longer have the inaccurate labels: 
  +1 octave and +2 octave. As the documentation states these are not
  octaves, but the first and second harmonic for a sine wave.

- Buffer is now "dynamic" as opposed to "static". This means that
  SimSynth only allocates the amount of memory it needs for each
  preset when you press MAKE, rather than grabbing and holding about
  three and a half meg, as in previous versions.

- Because of the dynamic buffer allocation, it was possible to increase
  the envelope times. This will not affect existing presets.
  This allows you to configure a preset that is much longer in
  duration than was possible with previous versions. However, you must
  have enough RAM, (roughly 176k per second). If not, MAKE fails.

- The frequency of noise with "detune" is now modulated by the LFO and ENV
  parameters. This may affect existing presets if they use detuned noise
  with ENV or LFO modulation, even though the modulation was not working.
  Turn the modulations to zero to correct the preset.
