 ===== 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!
 ==== Jog Wheel ====

 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.
 ==== Software ====

 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.
