here's a suction pump from a fire engine on ebay - http://cgi.ebay.co.uk/Suction-Pump-Branch-Ex-Fire-Engine_W0QQitemZ200012428612QQihZ010QQcategoryZ396QQrdZ1QQcmdZViewItem or maybe a dental suction pump: http://cgi.ebay.co.uk/Dental-Suction-Pump_W0QQitemZ150017257174QQihZ005QQcategoryZ31458QQrdZ1QQcmdZViewItem but the absolute best thing would be a lab suction pump, they'll perform much better than a fridge pump (I saw one of those on the street today) - keep an eye out on ebay, i'm sure they must turn up. or if you live near Bangkok, I hear stories about some of the girls out there.... btw: what size are the buttons?

hey Moxi, I meant using the pressure cooker as a vacuum vessel, will be very well sealed and u can pick them up cheap at charity shops/ebay etc...

have you thought about trying a pressure cooker?

so they do - I stand corrected., The ALPs site doesn't make mention of a Linear version available in the non-motorised version - must remember to double check Conrad's site in future when sourcing pots... thanks for the info Sasa

Sinnsyk, I said "previously mentioned" - not by who ;) And btw: those Alps K-Faders are not linear, only the motorised version is linear.

tos, the answer has been said numerous times - I said check the graphs on the link - I assumed they were self explainitory, I'm not treating anyone like a newbie. Love the sweeping generalisation - am a little worried about the fact you must be stalking me as I don't remember meeting you ever! As for not listening - to what did I not listen to? the point is - I don't think any mixer companies are using a linear fader on their x-faders, the ultra nice ones I've seen of late are optical. The simple answer is and always has been - get a nice 10k Fader like an Alps or P&G. As for I've never worked with a mixer - I'll skip the "I've done this and that, and played here and there" and just say :P really, it "should" should it? On every x-fader on every mixer on the planet? Jesus I better go out and get the x-fade on my Formula sound mixer fixed. And the rotaries on my xzone:v6 are really stiff - i better get those fixed too because they obviosuly should be light as as a feather, and then there is my Urei I can't even find a cross fader on it, ooops better get that fixed too! I can't see any reason why you can't find a high quality fader that will do the exact same job better than or equal to any x-fade unit in any mixer, in fact if you buy a fader you get a lot more choice if you are willing to look. where do you think Rane, Allen & Heath, Neve get their faders and x-faders from? you think they make them in-house? go straight to the place the best in the business go to and get exactly what you want/need by doing it DIY, that's the midi-box way right? may I ask what exactly it is you have answered by joining in?? or did you just feel like showing off your encyclopedic knowledge of Dj mixers off in public?

yup - that's why I chose vitrail. I can't wait to start experimenting... btw: have you got any pics you can post?

excellent news - I have some Lazertran that I've ordered but haven't had a chance to experiment with, glad it's as good as they claim. I'm planning you use a "liquid glass" coating called Vitrail which is used for Glass and Cermamics as well as usable on metal.

okay - whatever, I've tried as best I can, go ahead spend lots of time and effort before you come to the conclusion that you should have used a standard 10k fader..

aaarrrgggghhhhh - Sasa, are you deliberately misundertstanding me? read this: http://www.rane.com/note146.html then think about this: a normal 10k fader works fine in abeton to control the x-fader - (i actually tested this myself as I had the same question as you, but decided to actually test it out before asking questions), so if the x-fader has a different respose curve than a standard linear fader, what do you think the result is going to be? an no - x-faders are NOT better quality than normal faders, why do you think they make them user replaceable? because they die regularly through use!! read the link I sent, and if you are still having problems getting your head around it, then go out and buy an x-fader and see what happens!!

so you tried a normal 10k fader, assigned it to Ableton's x-fade and it worked: why on earth are you looking to use an x-fade from a mixer???? if it's that you've got too much cash around at the moment and you're looking to get rid of some, send it my way ;)

have you seen the graphs for x-faders??? have you ever used a Rane, or an Allen and Heath? How about a soundcraft, you'll find they have different slopes in the middle! and now for the final killer question: hands up who's actually tested using a fader on Ableton assigned to the x-fade???

SOME mixers use VCAs for the x-fader, but not all, generally more expensive/old skool mixers.

Right - so I didn't miss your point the 1st time. If you want a cross fader to use with say ableton - it's really really simple, get a standard 10k Fader and bam! you are done. If you want a center denent they get a 10k fader with done, choose knob you like and you are away- and it'll be massively cheaper than buying a fader as a spare part. Alps make great faders or if you are feeling rich go for a P&G

what application are you going to drive with the x-fader? is it ableton or traktor?

but the problem with using an x-fader on an Midibox is that the x-fader is designed to take 2 stereo inputs and mix them - I don't think this will work with a midi box (please correct me if I'm wrong).

you just need a normal 10k fader, and then assign it to the x-fader in the application (i.e. ableton). You might want a different knob on the top because of the way it's used and mounted will be different to the channel faders. The size come down to preference and style - turntablists and scratchers like short x-faders, 3 minute mixers will perfer a longer one

Hi all, I know it's a bit off topic, I hope no one minds. I'm having a bit of a problem with my laptop and quattro. As soon as I plug the USB from my laptop to the Quattro I get terrible noise problems, even with the audio leads disconnetted from the mixer! As soon as I pull the power to the laptop and go onto to battery it goes. Is there a way to sort this with the current gear WITHOUT pulling the ground pin on the power to my laptop adapter? It's my idea of a nightmare being at a gig on stage / in a DJ booth with an adapter about and no ground, I've had 3 club electrocutions and I'm in no rush for my 4th, also the power isn't the best in a lot of places, especially illegal parties. Or is the solution the most obvious painfull one - go out and by a MOTU traveller?

what sort of speakers and amps you looking to build? Studio/Home/PA? Personally I'm dreaming of building some PA speakers like a Martin Line Array on the mids and tops and using a Transmission Line design for the subs like PMC do, but bigger.....

pkniffer, is there a freaky door where you are? How about a clock? What about an eyeball? if you've answered yes to more than one of the questions above, it could be that your travelling through a dimension. A dimension of not only sight and sound, but of mind.... sorry - I tried, but I couldn't resist...

mmmmmm, It does seem like the whole analogue side of things isn't working... I put another PIC in there and the same thing - I guess I might have blown both of them, it would be strange as I've been very careful... I buzzed all of the pins on J5 to the PIC socket and they are all cool, so I guess the only thing it can be is fried PICs - doh! now I need to figure out why the PICs are dying on me....

Hi TK, Thanks for the reply. Even with a pot connected directly to the core on J5:A0 I'm still getting no midi data / or any indication on the LCD of AIN activity. The DINX4 I've built works like a dream as does the LCD. Should I be getting random midi stuff because the A1-3 are unused and ungrounded?

Hi All, I've got a problem with my core - it's not getting any ain data. I've loaded various apps, currently playing with the ain64_din128_v1_3 app. I've tried using an AINX4 I've built - no joy, I've checked all the connections ten times over, buzzed all the cables out. So I've now connected a pot directly to the core. J5A on the core - VS and VS to the outermost legs on the pot and the center leg going to A0 In both cases, using the AINx4 and directly to the core I'm getting voltage on the pot and it's sweeping up and down like it should. and I'm still getting nothing, I was expecting lots of random midi stuff at least, as the other pins aren't grounded..... any suggestions as to what I need to do next in the troubleshooting process?? thanks d

nice tips thanks

Smash, Lol, Yes we English do talk funny, but since we invented the langage we reserve the right to do so... Tell your wife there is no need to be jealous, unless of course you happen to look like a pretty bruenette with big dark eyes, long hair and pert bussoms. > "tell him I'm jealous, and that you are loverly, but not that lovely" What your wife is refering to would be classified as a "lovely, lovely man", which is a rare and high honour indeed, it's sort of like Knighthood for being super-cool. It's something we can all aspire to becoming ;)
