They're both LFSR-based using different seeds, and one is at 2 kHz instead of 1 kHz. If N2IT got Native Instruments to settle, I don't see why they couldn't get Rane to settle as well. (Perhaps the regions where the patents have been granted have something to do with it.) Peter: An interesting twist is that the Traktor Scratch timecode works the same way as the Serato timecode.

Odd to think it's taken this long to do it with turntables... I’m not certain, but I believe one incarnation of Laurie Anderson’s magnetic tape violin bow used control code instead of audio.

So determining the direction is a matter of comparing which waveform on the respective channel is leading. Determining the pitch is comparable to comparing the zero-crossings to the ones expected on the original waveform at 1khz - repectively at 33rpm. So the only parameters for pitch detection are: phase of the waveform (starting either at 0 or 180 deg) and the frequency of it. So I'd be surprised if exact pitch information couldn't be extracted from any of the available timecoders regardless of the used timecode-vinyl by adjusting the input channels/exchanging them and multiplying the decoded pitch by a constant factor. Regardless of this, I am interested to see how the timecode for the other vinyls is encoded.

I should have said "mainstream DVS." Of the sort of major packages, Serato was the first. Even they're doing it as a plug-in, though, so I don't know whether that "counts" or not.

It just kills me that there's no way to read and interpret vinyl control techniques while using real records. The Numark X1 is interesting in that it uses a special spindle and "control platter" to allow for vinyl-style scratching of CDs, but it's not the same thing as scratching a regular record, and there's no obvious way to do it. Clearly we need smarter people than me working on this issue... :) @nkem – You’re right, instead of “platter” I should have said record.

You want a turntable that sends midi data to the computer based on "the hardware (platter speed / direction, tonearm position, etc.)" regardless of what the vinyl is doing? This doesn't make any sense to me. You don't cue a record with the platter... and you certainly don't scratch with a platter. Some djs only change the speed of a record with the platter & speed controls, but every dj has to touch teh vinyl at some point or another... some more than others. Never heard anyone with such a request before. @beatfix,

Full support for the Torq vinyl is also present in the SDK. "Only recently did a DVS, Serato, take on visuals..." Actually, Peter, I believe MsPinky was scratching visuals with MaxiPatchAV from the get-go...so technically scratching visuals with DVS has been around almost as long as DVS itself :-) Re: Torq vinyl, I believe that support for all iterations of MsPinky vinyl, including Torq, is included in the Max objects, even for absolute mode.

Of course it's not a self contained piece of hardware, but you might be tempted to forget that once you see the results. Aesop Rock's dj had a routine scratching video samples on ace's last tour. It was really fun (scratching an old 50's coffee commercial). Also, isn't there some kind of DVD faxcimile of CD decks that puts out video? I'm pretty sure that might get close to what you want- google around. beatfix, I believe with this max/pd app this might be close to what you’re looking for.

I thought to myself, "Awesome, but too bad it doesn't work with my regular records somehow". I've been following the digital vinyl scene ever since (Ms. Pinky, Final Scratch, Serato, Torq), and was always a bit put off by the fact that they all required this layer of timecode interpretation - always seemed inefficient to me. Just recently I saw a Numark product that perked my interest again - the X2 hybrid turntable. It's a fully functional vinyl turntable, that also uses the platter as a control device for CDs. http://www.turntablelab.com/dj_equipment/48/11/21438.html When someone makes a working turntable that also outputs control data (such as MIDI) directly from the hardware (platter speed / direction, tonearm position, etc.) - I'll be first in line to buy one. Finally, I will have the ability to mix, pitch, and scratch my existing records and simultaneously send control data to computers / video / what-have-you.
