APPENDIX 1: MISC. INFORMATION

Hard Reset

From time to time you may encounter a situation which locks up the DDP's software. Usually this is due to operator
error. Which means you asked the DDP to do something we did not anticipate in the implementation of the software,
or something else has locked up the DDP. It may be necessary to do a "Hard Reset" Perform this only when there is
no other option, either by turning off and then on, or moving to another area in the software and then back again.
To do a Hard Reset:
1. Turn the DDP off.
2. Hold down the Store button
3. Turn on the DDP.
4. When the asterisk appears in the Parameter 1 line, press Next Page button.

Change Default Startup Program

The DDP turns on in "Program Mode" and is ready to use without any other keystrokes being necessary. The DDP
"remembers" the last program number used, and stores that program number as the default startup program number.
Occasionally you may wish to manually manipulate this setting. Do so by holding down the Program button while
turning on the DDP.

Front Panel Lockout

The DDP's controls may also be locked, effectively disabling the front panel. Holding the Utility button while turning
on the DDP displays an instruction screen telling you to press the Prev Page button to toggle the locked status. When
locked, the program name line flashes between the name of the program and the text, "DDP Locked!" Unlocking the
DDP controls is accomplished the same way. Note that when in locked mode the DDP can still be controlled via MIDI
operations, as well as SysEx commands and CC information.
Type IV™ Conversion System
We have included the Type IV™ Conversion Process as the primary method of analog to digital conversion on the
DDP. When the analog inputs are selected, the TYPE IV™ icon to the right of the program number lights up and the
TYPE IV™ process takes over as the means of converting the analog signal to a digital signal. This means that you
may hit +6dB on the digital input meters for the DDP and not hear any audible distortion. This behavior is not unlike
an analog tape machine. In conjunction with TSE™ Tape Saturation Emulation, the essence of the analog signal is cap-
tured to the digital medium in a way that preserves the color and emulates the behavior of an analog tape recording.
This process results in a digital signal that is more pleasing to the ear, and offers a more musical, useable signal for
the DDP to process, resulting in master-quality sound output, whether digital or analog.
TSE™ -- Tape Saturation Emulation
Analog tape has always had a specific "sound". In fact different brands of magnetic tape have their own peculiar
sound or "color". The color is most apparent when you drive the tape hard, almost to saturation. Conversely, digital
signals have almost no "color". If you drive a digital signal to saturation, all you get is an ugly, unuseable "digital
over" sound, much like fingernails on a blackboard. As a result, the sound, while crystal clear, can have a sterile or
crisp sound. It is this crispness that has been the downfall of digital signals. Tape Saturation Emulation™ is a process
yyyyy
of giving a digital signal an analog-type sound or color, making it more pleasing to the ear. On the DDP you can
drive the input past the zero mark without risking the dreaded digital "over". Instead you get a pleasant saturation that
is modeled after the sound of analog tape being saturated with signal. the controls for TSE™ are in the EQ section,
and are global in effect. There are five different settings for TSE: Dark, Warm, None, Bright and Brighter. Each emu-
lates an analog signal's "color" and is very unique. Their names reflect their characteristics.
The controls for TSE are always active. If you do not want any coloration added to your signal, simply set the controls
to "None".
