 ===== Design =====
 ==== Crossfader ====
-The crossfader is the simplest part of the project. There are a number of faders on the market specifically designed for scratch DJs. For example :

-The analogue ins of the PIC mean the fader can be used with no additional circuitry. Hooray!

 I put the two photodiodes into two voltage dividers and wired them into pins 4 and 5 of the PIC. The comparators of a PIC18F4620 (or 4685) can be used to avoid extra circuitry.

 The MIOS code tracks the encoder wheel, and counts the number of forward and backward steps. Then every couple of milliseconds it sends the relative position as a CC event. The value of the CC is equal to 64 (0x40)plus/minus the number of steps, for example for 10 steps back the value would be 54 (0x36).
-There are quite a few DJ applications that support MIDI scratching in this format, the two I've tried are [[http://www.mixvibes.com/|Mixvibes DVS]] and [[http://www.native-instruments.com/index.php?id=traktor3_us|Native Instruments Traktor 3]]. M-Audio Torq doesn't work as of the current version (1.0.6) as it has a bug in the MIDI code.

 This is how to build the device the way *I* did it. It's not pretty (see photos) but works acceptably. It could be improved upon immensely if you have any actual construction skills, metalwork experience, access to a CNC mill, etc.

-[[http://picasaweb.google.co.uk/rasteri/Scratchtroller/photo#5216080810302030418|This schematic]] shows how to wire everything up to the PIC. Should be trivially adaptable to work with a "real" midibox core module.
