Chapter 4 Mixer & Audio Controls
determines the amount of output signal coming directly from
the source. That means you can control the ratio between the
source signal (Dry) and the output of the Digital Effects.
Normally, the Dry control is set at the maximum level to hear
both the source and the effect. However, the Dry control can
sometimes be set at the minimum to listen only to the effects.
A level of 0 for the Dry control will result in a totally affected
(Wet) signal, providing that the Reverb, Chorus or Variation
levels are greater than 0.
Reverb, Chorus and Variation Effects
The Audiotrix 3D-XG is equipped with 3 powerful DSPs that
allow the choice of Reverb, Chorus and/or Variation effects.
These effects can be selected using the drop-down boxes and
the intensity of each effect can be controlled by using the
corresponding sliders, entering the intensity values in the edit
boxes or using the up & down arrows.
Locking the Digital Effects
The Lock check box allows the audio (Mic, Wave, CD audio,
Line-in) and the variation effect to be locked. This is
important because whenever the Audiotrix 3D-XG receives
subsequent SysEx commands, these will not effect the audio
or the variation effect. Once locked, the Digital Effects
Control cannot be changed until the Lock box is de-selected.
The purpose of the lock command is to force the audio portion
of the sound card to remain active. Generally, when a MIDI
file begins to play, a GM On or XG On command is sent
which mutes the audio part of the sound card to provide an
additional 2 notes of polyphony (30+2=32) to the MIDI part.
If the Digital Effects control is not locked, the audio output of
the sound card will be muted as soon as the MIDI file begins
to play.
To reactivate the audio output, click on the Reset button of the
Audiotrix 3D-XG Mixer when the MIDI file has finished
