The UberMixer is inspired from the Aurora Mixer 224. I've been thinking for some time to create a custom mixer/controller for Ableton Live, but I've recently bought Traktor Scractch Duo and it's the perfect time to create a mixer/controller for Traktor.
In brief, the UberMixer is running a ATmega164P at 20 MHz with a 16 channel analog multiplexer. A FTDI USB chip provides the interface to the computer using a MiniUSB connector. The device is bus-powered and will appear like a MIDI controller to the computer. The user is provided with a 3 band EQ (Hi/Mid/Lo), gain, Filter with on/off, track volume, 4 loops + out for each track, cue prelisten, along with monitor and master volume. Traktor will also feed back the dB values for each track, which will be displayed on the VU meters.
