This topic describes how to use the crystal surface in Open Sound Controller (OSC) mode.

What is Controller Mode?

If crystal is ordered as a surface only, then it can communicate with an external OSC device such as a DAW. Typical applications include workstation control or integration with Lawo's mc² consoles.

Please note:

  • The external device must support the Open Sound Control (OSC) protocol.
  • The crystal frame can be fitted with either a Fader or Main module.
  • Each crystal frame must connect independently to the IP network; a CAN bus daisy-chain (for a second frame) is not permitted.
  • The OSC syntax is fixed. An OSC mapping table is being prepared and will be added in the future.

Integration with mc2 Consoles

In controller mode, up to 4 crystal modules (Fader or Main) can control each virtual mixer slice (in the A__UHD Core). So, for example, if there are 8 virtual mixer slices, then these can support up to 32 crystal frames/modules.

For more information about how to configure crystal with a mc² system, please contact your local Lawo sales representative.

Configuration Steps

On the crystal side, each frame must be configured to operate in OSC control mode. This is done by opening a Web UI connection to the crystal frame and adjusting the parameters in the "System → Control" tab.

The Web UI can be reached by entering the current IP address. The default IPs are 192.168.101.242 (for a Main module), or 192.168.101.243 (for a Fader module).

Log in as either Supervisor or Administrator. The default passwords are orion for Supervisor and hydra for Administrator.

Then open the "System → Control" tab and perform the following steps.

  1. The Module Control Mode option (under "Control Functions") must be set to OSC Control.
  2. Use the "OSC Control Interface" settings to configure the network communication to and from the OSC device.
    • For the receive port, enter the port number (that will be used by crystal to listen for OSC messages).
    • The two send ports can be used to transmit OSC messages to two separate devices. In each case, enter the IP address (of the external device) and a suitable port number.
  3. The Upload Firmware button can be used to upload a new firmware to the module. At the end of the upload, the module reboots. 

Providing everything is correctly configured, the crystal is ready to communicate with the OSC device. You can use the Web UI to change or modify the settings if you need.

To return to Power Core mode, set the Module Control Mode option back to PowerCore Control and then reboot.
