So... Rasteri sent me the schematics and I think its a fun project. Might not be price-worthy in the end but its cool to have your own built stuff. Anyway. At work I'm learning this new CAD-PCB program so I needed I project to work on. So I asked Rasteri if I could use his circuit (made some minor changes) and this is the result. Its 89 x 62mm so you can build a very small mixer if you wanted to. I made this for learning so I'm not gonna sell it or so. The amount of time to fit the PCB is just to much. Just gonna make one or two for fun. A big thanks to Rasteri for his time in making this faderbox.

etching. Its almost like developing a picture. You need a UV-box and chemicals. The circuit:

I got a 07 ISP at home and it doesn't have line in so I made a little conversion board so I can use Serato. I works just fine and doesn't need external power. Instead of making a box that needs RCA-cables I put it inside and made switches on the backplate. If anyone is interested of a PCB i made 2 extra while I was at it.

yea... You sure its for the room Steve?

I would put in a tenner to

Many good vids! 1: Chinmachine2: Fakser3: IQ4: JesusKut5: TieNo6: FlipFlop7: Mighty Atom8: Dopez

Good topic! There are so many videos out there where I can listen for 4 seconds and know how its gonna sound all way through. 2clicks sounds awesome but is used to heavy and without recordhand variations. When I was thinking of a beat for the battle I first was gonna use a "ducka du ducka du ducka" blah blah double-time and on and on it goes" beat. But I went for a different tempo that would be more funky but maybe less technical in my mind. In retrospect I think that might cost me a top 8 place. I should have done a 2click/3click mayhem instead. People love that.

Got loads of email concerning the DjTech battle. Feel obligated to enter now.

The thing is that it starts to oscillate if you tamper with the 301 output to much. But like you said using a ADC from the original fader instead of a extra fader is the best option. There are some drawbacks with this also but it can be fixed with some clever coding (I hope).

edit: (back from bingeing,((is bingeing a word?)): When I say that the strobe goes crazy that something a human eye would not see at all. Its still just a pretty red light for us. But the dots on the platter moves in myserious ways

I have never shared this really. Dont know why... Here goes. When I only had technics at home (2 years ago) and my friend had a vestax I wanted the low pitch so I started to experiment with the technics pitch function. First I made mods to the actual pitch function lowering the resistance from/to the pitch controller chip. With this you can get down to really low pitch like -70% but it flutters like you are doing a hydroplane. Then I found out that you can change the internal oscillator to make it go faster or slower. This is prefect stabile but makes your strobe go crazy cause its contolled by the oscillator. So if you want to make your turntable go fast or slow you can do this cheap and easy mod. This is pasted from a mail I sent to turntabletech cause we exchanged info. I wanted to know how the tourqe mod was done and they got this from me in exchange. ------------------ Here is how you do it. Its fairly simple. I have been trying different methods but this is the only one that is stabile in speed. I checked with Serato and it differs +- o.o1% while running. Desolder the original crystal at X201 on the mainboard. Solder in cables to a switch. I made a little drawing of it. See the attached c-switch.jpg I only want my turntable to go slow so I only use the original crystal and another with lower MHz (2positions).But of cause you can use a rotating switch with many positions and use more crystals to even get it to run faster. Pitch range with the crystals I have tried.This is not exact values (at all) cause I don't really remember, try it yourself. 4.9167...MHz +8% to 28%4.1932...MHz (original) -8% to +8%3.5795...MHz -21% to -3%3.2768...MHz -10% to -30% Keep the cables to the switch as short as possible to avoid oscillation issues. Very important!!!Solder the crystals directly to the switch.I attached another picture so you can see where I put the switch. Not the best position cause I had to carve out the rubber casing. But it close enough to X201. To make this work you have to cut the orange cable running from the mainboard to the pitchfader. It disables center click zero point. You maybe have to adjust the zero point after trying this.------------------ This is fairly simple to do but to make a nonstepped ultrapitch demands that you have a variable oscillator. I found this easiest to do with a digital circuit. And thats where I am now. Im trying diffrent variations. I want to include a transmitter so you can have the "ultrapitch" in a separate device (like a remote) without having to drill in the turntable as "technics people" sometimes are non willing to change the apperence of a their classic.

I have tried it out. My technics goes -30%. I have tried -50% and the technics cant really handle it. You loose tourqe! But its stabile. I can make a vid and show it if anyone wants to how it behaves As a matter of fact Im looking into the ultra pitch thing. It can be done. My biggest concern with this is that you have to drill in the technics and that is a pain. Was looking into making a remote ultrapitch. But if someone else is doing the same thing I might not proceed any further.

Sweet routine! No complaints from me! I really like the intro and first juggle You got my vote.

and fuck yea! http://djworx.com/vestax-pdx-2000-midi-mod-soldering-at-your-own-risk/

Tested on both original and mk2s now. It works just fine. All info is here. http://pdx2000midi.eu.pn/ 55 quid is the final price (Sy I owe you two beers from now). Trying to get the flight money for CS BBQ and SSS in august. I can install it for everyone who wants it at SSS if I get there. Can someone house me from sun to mon in Rye if come over?

I have a 07 that I is fitted with an inno. I had no problems calibrating or anything. It was the old one not the PNP version. Got the best results putting the CF curve at 12.

Thanks for the nice feedback on the vid

One of the best beats in the beat battles yet! Love it

Cant juggle myself and I don't make routines so I usually never comment on the DMCs. But nothing of what I just saw was even close to interesting.

I think I can help you anyway Sy. If your up for some instructions over skype (just because the pitchboard pcb is a little different so the pdf instructions wont look the same).

I need two people for testing and feedback who wants the mod. Not mk2s cause I haven made instructions or tested them yet. Just PM me: Installation instructions: http://pdx2000midi.eu.pn/PDX-2000_MIDI.pdf The mod costs 65£ + shipping. Shipping: EU w/o tracking 6£ EU the with tracking 12£ Worldwide w/o tracking 8£ Worldwide with tracking 15£

Yes. That is possible and was my initial idea. But I found it more useful to be able to change the root note with the +-10% if you had a outoftune sample or just want to change scale. If someone really wanted to have this it could be done tho. With the use of dvs and preprod software 20 notes should be enough.

Finally! Here is the finished product. Will release instructions and info in a couple of days.
