    Once the drivers are installed, you can simply plug aurora into the computer’s USB port. NOTE: Plugging aurora into a low power USB hub will make the device operate incorrectly. To operate aurora’s ambient lighting with Max5, the Max5 patch requires tempo input.

  • Page 4: Assembly

    Assembly The Aurora 224 is easy to assemble. Start by snapping the button caps (7) onto the PCB assembly (6). Then align the bottom panel (9) making sure the mounting holes line up with PCB. If they don’t, flip the bottom panel or rotate it so that they do, making sure you stack them as shown.

  • Page 6: Protocol

    Protocol Aurora uses two simple serial protocols for sending and receiving data at a baud rate of 57600. These two protocols can be easily sent and received in MAX/MSP and Pure Data (pd) by using the virtual COM port created when the Aurora is connected to your computer via a USB cable.

  • Page 9: Aurora Pd (Pure Data) Setup Introduction

    Aurora PD (Pure Data) Setup Introduction The aurora / PD interface allows the mixer to transmit and receive data using the USB port. The PD interface receives data from the mixer and converts its into MIDI CC messages. The PD interface transmits red, green, and blue color data using a scale of 0- 255 to indicate brightness.
  • Page 10 Check to make sure that Mapel Midi Out ports are showing up. If not, install the Maple Midi driver. aurora_pd_debug This file can be used to read out the CC data coming from the mixer, as well as test the LEDs on the PC board. To specify the comport in PD, simply press ctrl+e to enable editing of the patch.
  • Page 11 pd_auroramidi.pd \ pd_auroramidi_abletonlive.pd These files read CC data from the mixer and translate them into MIDI CC values. CC values 119 and 120 are handled differently between these programs. Use pd_auroramidi_abletonlive.pd if you plan on using Live. The program looks like this: PD’s midi output port must be specified, the Maple MIDI drivers should be installed.
  • Page 12 Select the output device and pick one of the MIDI outputs (this port number is important, your other MIDI programs will need to be setup to read this port) When you are finished it should look like this The device is now configured. Enjoy.

  • Page 14 Press the button to Set Midi and select your MIDI output port, this port should also be setup in your favorite Midi Program. The rest of the on screen display is used for lsynth, aurora’s ambient lighting engine. Depending on which Max5 patch you downloaded, the light effects will be either random but tempo synchronized or controllable and tempo synchronized.
  • Page 15 A few things in Max should be set up before you begin: Make sure your MIDI drivers are set up.
