=====================================
THE AUDIOTRIX PRO DSP/VOICE PROCESSOR
=====================================
The Audiotrix Pro DSP/Voice Processor is a powerful daughterboard
that is capable of producing multiple simultaneous digital effects
with real-time dynamic control over the level of each effect
selected. These effects can be applied independently on the OPL4
music and to the voice/or microphone. The effects can be implemented
in DOS and Windows, and may be turned on/off very easily.



==================================

=======================================
INSTALLATION OF THE DSP/VOICE PROCESSOR
=======================================
This section outlines the changes made during the installation
process.

These files will be copied onto your hard disk in the following
subdirectories:

    \TRXPRO\EFFECTS\*.GLO
    \TRXPRO\EFFECTS\EFFECTS.EXE
    \TRXPRO\EFFECTS\EFFECTS.HLP
    \TRXPRO\EFFECTS\EFFECTS.INI
    \TRXPRO\EFFECTS\BWCC.DLL
    \TRXPRO\EFFECTS\YSS225.CFG
    \TRXPRO\EFFECTS\YSS225.DRV
    \WINDOWS\SYSTEM\YSS225.CFG
    \WINDOWS\SYSTEM\YSS225.DRV

The following line will be added to the \WINDOWS\CONTROL.INI file:

    [drivers.desc]
    yss225.drv=Audiotrix Pro Effects Processor

The following lines will also be added to the \WINDOWS\SYSTEM.INI file:

    [drivers]
    Aux1=yss225.drv

    [yss225.drv]
    Port=xxx
    Aux1Gain=0
    Aux2Gain=0

The installation procedure will also add the effects processor
interface with the "-i" parameter in your startup group.  This
initializes the effects driver and reloads the values saved
with the "Save Settings" command in the effects processor
interface.

Your old SYSTEM.INI and CONTROL.INI files will be renamed SYSTEM.FX
and CONTROL.FX should you want to return to them sometime in the
future.



===============================
