9.Click OK. The DSP Configurator program is connected live to the device and the configuration and presets are pushed or pulled as selected.

•If Pull is selected, the program overwrites the currently open file with the configuration from the device. Proceed to step 7.

•If Push is selected, the program overwrites the device configuration with the currently open file. Proceed to step 7.

NOTE: In either case, the program and device configuration now reflects

DSP Configurator changes in real-time.

If the file has been previously saved and has not changed, step 7 is skipped.

10.If changes have been made to the DSP parameters (including mix-point, gain or processor blocks) since the last file save, DSP Configurator prompts to save the file. Click Yes or No, as necessary,

a.Click Yes to save the currently open configuration to an existing file or to create a new one, then proceed to step 8.

b.Click No to push the currently open configuration to the DMP 44 LC. After the configuration is complete, DSP Configurator remains connected to the DMP 44 LC in Live mode.

11.Either enter a new file name, or select an existing file from the list then click Save. The DSP Configurator program uploads the current file to the DMP 44 LC. The file overwrites the configuration of the device, and DSP Configurator is now connected live. Further changes to the configuration will be reflected immediately in the device operation.

Presets

Presets are used to recall a group of frequently used settings. Presets created by

DSP Configurator may contain all elements (gain blocks, processor blocks, and mix-points) or a portion of the elements available within the program. In Emulate mode, up to 16 presets can be created, then uploaded as a set and stored to the device or stored to disk as a configuration file. In Live mode, presets can be created one at a time from the current state. They can then be saved to a chosen preset number in the device, with the option to name, rename or save to disk.

When recalled, a preset only overwrites elements contained in the preset. Presets are useful when settings for a particular room or only certain elements of a configuration need to be changed regularly.

An additional preset contains current state information if reading from the device in Live mode, or the state of DSP Configurator if in Emulate mode (titled current emulation). Current emulation can be a configuration not yet saved as a preset (work in progress), the last preset or combination of presets recalled within DSP Configurator, or the current state of the device as a result of switching from Live to Emulate mode.

Presets may be created in Live or Emulate modes. In Emulate mode, the preset or presets are created, saved to a file, then pushed to the DMP 44 LC when connecting in Live mode.

When a Pull data synchronization is performed, preset data remains in the DMP 44 LC, with only the list of preset names pulled from the device. Presets in this state are marked with an asterisk until that preset is recalled (which pulls the preset data from the device), or until a backup is performed. Presets pulled from the device cannot be saved to disk until they have been recalled, at which time the preset data is pulled into DSP Configurator. Presets with no asterisk can be saved to disk.
