Midi settings

Most of the UI controls can be mapped to a midi controller.
The UI supports midi learn from any midi device

• Press AltGr + M on a given screen of the application to map a control to a midi controller

• Click on the control to map and click on “Enable for mapping”
• Use the controller button that must be associated to the UI control
• Press Escape to quit the mapping mode

• Press AltGr + k on a given screen of the application to map a control to a keyboard key

Click on the control to map and click on “Enable for mapping”

Press a key on the keyboard to assign it to the UI control

Press Escape to quit the mapping mode

Load mapping	Loads a saved mapping file
Save mapping	Saves all mappings in a mapping file
Show mapping window	Displays the mapping table for midi device and keyboard
Midi device	Select a midi device in the list
Incoming midi message	Display the incoming midi message values

OSC Settings

NESS can be controlled with the OSC protocol with the TouchOSC application and the available here .

NESS also supports the ADM OSC protocol for the control of the sources

NESS receives osc messages on the port 4000

When the TouchOSC app is connected to NESS The message « TouchOSC connected » is displayed in green

OSC Settings
Network interface	Displays the IP address of the selected network interface

Nota : this requires Java runtime engine to be installed

OSC Settings
Incoming OSC message	Displays the OSC messages on the port 4000 received by the software
Sender	NESS can also send OSC messages to up to 4 other devices
IP address	IP address of the mobile device on which TouchOSC is installed or IP address of the application to control
Port	UDP port on which NESS sends OSC messages

Spatialization Settings

Rollof (dB/ double distance): sets the level decrease law for the acoustic model of the DBAP. 6 dB is a usual value to simulate the acoustic propagation in an outdoor space. A lower value can be used to simulate the sound propagation in an indoor place. A higher value can enhance the distance effect, less speakers will play the sound at the same time, which can enhance the precision of the spatialization for small 360° setups

Atmospheric Absorption : activates or deactivates the high frequency attenuation depending on the distance.

Delay smoothing : smoothing coefficient for the delays. For sources with quick movements, this can create unwanted doppler effect (frequency transposition). The delays are interpolated and smoothed to avoid high pitch transitions. By increasing the value, the transitions are smoothed, but the delays will be less corelated to the source position, which can results in a slightly less precise localization.
