MDT UserÕs Manual51 Lesson 5: Using Automation
New Possibilities
You have probably thought of numerous applications for MDT that have
not been mentioned in the Tutorial. We hope that you have learned enough
about whatÕs possible with MDT that you feel free to experiment and create
ways to use it that are far beyond anything we expected.
Here is something to play with as a starting point that could produce
unique results in a sound design application.

CHAPTER 4MDT Reference
This chapter explains the detailed operation of every aspect of MDTÕs user
interface. The items are organized in alphabetical order to make them easy
to locate. 
Attack Slider
The Attack slider controls the amount of time it takes for MDT to react to an
incoming peak. The range of the control is from 0 milliseconds to 50 milli-
seconds. The current attack time is displayed in the window to the left of
the slider. 
Clicking on the arrows decrements/increments the...

The Settings menu is also automated. Care must be taken, however, not to
automate ÒSave Setting As...Ó or ÒDelete Setting...Ó because these dialogs
will be posted when automation plays back. Moving points in the I/O
Graph cannot be automated, although changing sets of points can be
recalled with the Settings Menu automation.
Bypass Button
Clicking on the Bypass button bypasses the settings of MDT. This is useful
for comparing the original soundÞle to the processed...

Clip Sentry Buf Len (mS) slider
A very short length will introduce distortion by making rapid gain reduc-
tions. This distortion will be minimal if Clip Sentry does not reduce the gain
too often or too much. A long length will introduce more delay in the pro-
cessed data and even produce audible drop-outs before transients on some
sounds.
Clip Sentry Release (mS) slider
If a large gain reduction occurs, a very short release will be less audible, but
may sound unnatural. A short...

+1,-1 values. After the yellow subsides, it latches to red. You may reset it to
black by clicking on it.
Control Surface Support
TDM pagetables have been implemented allowing MDT to be controlled by
external control surfaces, including the JL Cooper CS-10, Peavey PC 1600,
Digidesign ProControl and Mackie HUI.
Delay Window
The Delay Window shows the amount of time in seconds that MDT will
delay a trackÕs sound output. This delay is introduced due to MDTÕs Òlook

¥5 Band: The signal is divided into 5 equal bands, 2 octaves in width. The
frequency response of this mode is 0 Hz to the Nyquist, ±0.0 dB with
±0.3 dB passband ripple.
¥3 Band AP: The signal is divided into 3 equal bands with a special Þlter
design optimized for the ßattest pass band near unity gain. The fre-
quency response of this mode is 0 Hz to the Nyquist, ±0.0 dB with ±0.0 to
0.7 dB passband ripple.

Flat Button
Pressing the Flat Button equalizes the apparent input level of the bands dis-
played in multiband modes. MDT adjusts the offset of each band to equal
the apparent level of the quietest band. As long as you hold down the ÒFlatÓ
button, the spectral band levels are averaged, and input offset level adjust-
ments are continuously updated. Consequently, the average coloration over
the period the ÒFlatÓ button is held down will be neutral.

In/Out Display
The In/Out Display shows the position of the cursor when it is located
inside the In/Out Grid. The units displayed are in dB below full scale. The
In/Out Display shows the location of thresholds and terminators when
they are being dragged.
When dragging a threshold, the In/Out Display also shows the compres-
sion or expansion ratios of the curve segments on either side of the thresh-
old. Ratios expressed as N to 1 are compression ratios. Ratios expressed as 1
to N are...

All the possible points where the I/O Curve can exist are represented by the
In/Out Grid. It is divided by a diagonal line that represents the points on
the Grid that have input levels equal to output levels (e.g. -48:-48). Placing
the I/O Curve on this diagonal will cause MDT to output the signal at the
same level as it was input. 
The points on the Grid which have output levels lower than their input lev-
els (e.g. -48:-72) are located below the diagonal. Placing the...
