MIDI CONNECTIONS
The DDP has a full complement of MIDI functionality. The MIDI connectors on the Rear Panel are configured in
the traditional way: with an “In” jack and an “Out/Thru” jack. The DDP can be used in common MIDI systems at
any point in the MIDI chain. MIDI setup functions are accessed with the
Utilities
button and are generally the
same as the functionality you are used to with most other MIDI devices. Program numbers and setups may be
changed and bypassed via the standard MIDI commands. In addition, presets may be saved off of the DDP and
reloaded via the MIDI functions. Full SysEx and Continuous Controller functions are also a part of the DDP’s
architecture. A full explanation of the MIDI, SysEx and CC functions are discussed in Section 5.
THE CURVE WINDOW
After you have chosen a program, you will want to change some of the parameters to meet your specific needs.
One of the most useful tools available on the DDP for setting up a proper compression curve is the curve win-
dow. In the curve window you can see the combined effects of all compression-related parameters expressed in a
graphical format. The figure below shows the different parts of the curve window you will see as you edit the
gate, compressor, and limiter functions of the DDP.
When working with the sidechain EQ, or the in-line EQ, the curve window changes to show a graphical represen-
tation of the 3 parametric bands in a frequency grid. Your adjustments to the three bands are shown in real time.
Additionally, the de-esser has its own graphical way of displaying its parameters, as seen above. The frequency is
shown on the bottom, or X axis, and the amount is shown on the side, or Y axis. Again, changes to the parame-
ters are updated in real time.
