Connection
A USB A to B mini cable is used to connect the mixer to the computer. Maple
Midi or MidiYoke needs to be installed prior to operating the mixer. The control
software, either Max5 or Pure Data is also needed. Please review the section on
setting up either Max or PD to determine which software to use. The diagram in
a typical setup is included below.
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. In the diagram above, sharing the tempo with Max is accomplished using
the rewire interface.
Ableton Live, or another rewire host, must be started before starting Max.
Additionally, Max must be configured to receive data. This is accomplished
choosing “rewire” under Max’s DSP Setting menu.

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. Once they are aligned, insert the female #8-32 threaded standoffs
(10) into the bottom panel as shown. They should fit snuggly. Now place the large
spacers (8) over the standoffs. Place the PCB on top, and fasten it down with the four
little screws (5). They should be snug. Now place the small spacers (4) and lay the top
panel (3) down. Drive the long #8-32 screws (2) into the outer four standoffs. Flip the
entire assembly over and place an adhesive backed rubber foot (11) on each corner.
Finally turn all the rotary potentiometers to the left or right, and then press on the knobs
(1). Now you have your very own color blasting midi mixer.

In Circuit Programming
The source code for both PIC MCUs is compatible with Source Boost’s BoostC
PIC compiler: http://www.sourceboost.com/
Olimex’s MCP-USB is an MPLAB compatible programmer. They are available
from Sparkfun: www.sparkfun.com
In circuit programming is accomplished using the ICSP1 and ICSP2. Refer to the
schematics to see the pinout of the header, it is compatible with the MCP-USB
but will function with other programmers.
Additionally, when compiling code, enure that your configuration bits match the
config bits of the source on the website.
DO NOT LEAVE THE AURORA PLUGGED INTO THE USB PORT WHEN
ATTEMPTING TO PROGRAM
