Hello there, I want to use a large analogue pitch fader and turn it into a high res midi pitch fader for controlling my djing software (traktor Pro) The ones on my current controller are only 128 resolution and do not offer accurate enough tempo control! How would i go about doing this? Thanks Dan

Hello, sorry i haven't posted in a while... been a busy beaver! Well i have some news, the previous setup i was thinking about has changed. I have bought a behringer BCD3000 to use as my central mixer as it has alot more functionality compared to the m audio mixer. I picked up the BCD3000 for 109 delivered and it has lots more midi buttons and knobs for to assign to whatever i like. Plus it has a low latency soundcard built in which enables me to headphone monitor. i think the m audio is around 70 quid(would need another 80 for sc). I will also be adding a Korg nanopad as to have better control over things like looping and hot cueing. The x-y touchpad on this should come in handy for altering effects in ableton live etc. Its only 40 - 50 quid. The only thing lacking in my whole setup is the wheels on the BCD3000, they are not the best at low speeds, seem to be pretty low res. NOt complaining as this price however. So i will be building the scratch wheel (or 2) to accompany it all and should make for a pretty complete setup. im either going to have one scratch wheel and combine it with monitor cues so i can use it for both decks(if that makes any sense :s) or i will be building 2 scratch wheels (one for each deck) Also thinking of mounting it on a shelf. I think it will be hard to come across a hard case that will fit everything nicely. anyways i thought you might be interested in a little update ;) Dan

no problems! I am thinking i will do a project video of everything i do to help others. will post it on a youtube as episodes. Ok i am about to order my midibox core module and pic and i have a couple of questions; 1) what pic do i need (want to be sure) 2) I am in the UK, should i buy from mike's or smashtv? 3) is there anything else i should/need order? Thanks Dan

what a beautiful diagram, very clear and concise - well done. The only (trivially minor) fault i can see is you have mixed up labels 6 and 8.

Thanks for that! :)

Well i definitely think that the scratch wheel is worth 50 bucks, so its time to start building! ok so i have the following things; -- multimeter -- soldering iron -- old hard drives -- 7" vinyl -- buttons -- crap fader -- old mouse I need; -- project box case -- midibox circuits ( core module) -- conductive paint -- good fader (innofade looks nice) -- brass bush i am also not sure about a couple of things; how to wire everything up to the midi core module ( i have looked at the schematic but still not sure) is the picture of the circuit enough to go on? Are all the components on the circuit the ones included in the midibox core kit? best place to buy everything p.s - if you can think of anything i have missed i would love to hear it Dan

I forgot to mention that the diagram is all drawn to scale with the containing box representing the inside dimensions of the flight case. Actually found a cheap enough flight case on ebay which is the one i am doing my measurements on. The cool thing about this case is that you can whip off the lid completely as its a guitar effects rig case. This means the lid won't get in the way when you are dj'in! http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=370104230503 The interior dimensions of the flight case are 688mm x 296mm (area 203648) dimensions of the x session - 215mm x 264mm ( area 56760) dimension of scratch wheel - 250mm x 200mm (area 50000) so 203648 (flight case) - 2x 50000 (scratchwheel) - 56760(xsession) = 46888mm case area left, equating to a 216mm x 216mm area left overall for extra buttons (spaced over unused spaces) costs so far are; case = £37(ebay) x session = £64 (amazon.co.uk) 2 x cost of scratch wheel so if the cost of building the scratch wheel is less that say £25 in total (each) then i think this setup would be much cooler and better value than the numark total control priced at £155 (amazon.co.uk) p.s do you think the xsessions crossfader will be good enough for mixing?

Hello there, I am extremely impressed with all the ingenuity and hard work put into this project. :) I was looking to buy a numark total control but where is the fun in that!? This scratch wheel seems to be hundreds of times better and you get the fun of creating it yourself. So you have inspired me to come up with a little project of my own.... The idea is to have a nice flight case setup for my dj'ing. I want to use the scratch wheel with a m audio x-session midi mixer. It seems to get rave reviews and is nicely priced at 64 quid. Also thinking of adding additional midi buttons for kill switches and effect switches (extra space in case) I want to keep all expenses to a minimum. also came up with another iteration, possibly two scratchers either side of the m audio leaving some space for extra buttons above each scratcher; Let me know what you guys think, i am a bit of a novice when it comes to things like this but i love dj'ing!
