Vielleicht besser als der orig. finalscratch ????

Wäre doch möglich oder? Habe ja gesehen, dass es hier auch Leute gibt die einen traktorcontroller gebaut ham.

Einziges Problem was mir grade einfallen würde wäre das scratchverhalten. Beim rückwärtslesen stimmt der timecode ja nicht :)

Aber wenn man das Kontrollbit so schreiben würde, dass man die Richtung erkennts wäre das Problem ja auch wieder aus der Welt, oder ?

So habe mal den anderen topic kopiert....

Topic: tracktor final scratch  (Read 55 times) 

alogic

ODIO EL RATÓN (ambidiestro)

--------------------------------------------------------------------------------

me he estado fijando en diseños de otros y ponen un controlador para los platos de tracktor no se si solo es un encoder que en una direccion pulsa el boton de acelerar el tema y en la otra el de frenarlo o si realmente se pudiese poner en modo absoluto (por llamarlo de alguna forma)y que resalmente se pueda escratchear con el encoder

por que no me importaria conectarle un par de encoders a los platos , con una ruedecita almoadillada que roce con el disco y marque la velod¡cidad, alguien lo ha usado

saludos y todosamidi

very intresting .... http://home.germany.net/101-81660/LTC.htm

its about the timecode used for video. It's just a usual audio-track with highs and lows.

sorry, but its german 

After some deeper reading into it I don't think it's very heavy to realize for us (and the great MB-community).

There would be 2 informations our vinyl would need:

- The actual tempo

- The actual position

You see timecode is an audiolike signal, either a high frequency (1) or a low frequency (0). Lets say high is at 2kHz, low at 1kHz. At reading I recognized a low is the half frequency of a high. So the actual frequency doesn't matter, because you know the lows are the half freq.

This way it wouldnt be a problem to read that "binary" code in this audio signal which tells us the actual position of the track.

The actual tempo of the vinyl could be found out, depending what frequencies the highs and lows are. A slower played vinyl causes lower frequencies than a faster played.

Right way, ain't it ?? 

And why just synchronizing traktor with it?

With a midi timecode it would be possible to sync every sequencer !!!!!

Think about mixing your songs live from sequencer for testing it in the mix. ^^ wooohahaha

!!!!!!! THAT WOULD BE MORE AWESOME THAN FINALSCRATCH ALREADY IS !!!!!!!!

Wobei Tempo quasi unnötig is. LOL

Ich hoffe ich habe mir das Problem nicht zu sehr vereinfacht.

Könnte jemand versiertes mal was dazu sagen? Vor allem weiss ich nicht inwiefern die Leistung vom 18f452 dafür ausreicht?

Wie viele digitale Signale kann das CoreModul pro Sekunde verarbeiten? Beim scratchen werden dies nämlich einige, da dass Tempo ja quasi in die Höhe rast.

Habe gesehen, man brauch kein tolles Interface wie das finalscreatch. Das Teil is nur ne usbsoundkarte mit audioeingang. Es gibt andere Timecodeplatten, die man einfach mit der vorhandenen (asio) soundkarte zu nutzen sind und prima funktionieren.

DAnke trotzdem für den tip
