DSP/EFFECTS PROCESSOR
---------------------
The DSP/Effects Processor features the powerful Yamaha YSS225 programmable
dedicated digital signal processor chip.  Multiple simultaneous effects can
be added to the music with real-time dynamic control over the level of each
effect selected.

Specifications
    - Yamaha YSS225 Effects Processing DSP chip
    - Will generate effects over standard Ad Lib OPL3 FM sound
    - 64 Kbytes of 120 nanosecond Static RAM
    - Up to .75 second delay time area
    - Dedicated Windows 3.1 device driver

Software Features
     - Simultaneous Reverb (Hall, Room, Vocal and Plate) and Chorus to which
       you can add one of a choice of 6 effects: Flange, Delay, Stereo Delay,
       Pitch Shifting, 3-band parametric equalizer, 3D Audio and Wide Stereo
       effect.
     - Real-time control over generated effects through the Audiotrix Pro
       Effects Processor Manager.


EFFECTS/VOICE PROCESSOR
-----------------------
The Effects/Karaoke Processor is an Audiotrix Pro DSP/Effects Processor with
the added capability of processing the microphone input.  Effects may be
added independently to the microphone and to the music.

Specifications
    - Yamaha YSS225 Effects Processing DSP chip
    - Will generate effects over standard Ad Lib OPL3 FM sound
    - 64 Kbytes of 120 nanosecond Static RAM
    - Up to .75 second delay time area
    - 18-bit serial analog-to-digital converter
    - Dedicated Windows 3.1 device driver

Software Features
    - Simultaneous Reverb (Hall, Room, Vocal and Plate) and Chorus for
      both music and microphone input with the added option of sending
      not only the OPL4 but also the microphone input through one of 6
      effects: Flange, Delay, Stereo Delay, Pitch Shifting, 3-band
      parametric equalizer, 3D Audio and Wide Stereo effect.
    - Karaoke Engine (Voice Harmony Processing Software)
    - Real-time control over generated effects through the Audiotrix Pro
      Effects Processor Manager.


SAMPLE RAM/512K EXPANSION MODULE
--------------------------------
The Sample RAM expansion module permits replacement of any of the onboard
General MIDI instruments with an instrument located in RAM.

Specifications
    - 2" x 3" expansion module with 512 Kbytes of 120 nanosecond static RAM
    - No jumpers. The additional memory becomes automatically addressable
      by the OPL4 with no other special hardware configuration.
    - Windows 3.1 OPL4 Device Driver with supports for RAM-based sample
      playback

Software Features
    - RAM samples accessed by standard MIDI bank-change commands
    - Support MIDI Sample Dump Standard
    - Sample Dump Standard conversion utilities
    - Sample maker/Loop Editor/librarian to make your own instruments
    - Software Developers Kit for writing applications such as Games, Demos
      and MOD players that require RAM-based wavetable support.
