What?

vinylcontrol~ is an external that allows controling pd- or max/msp- (as well as sndobj) patches using timecode vinyl.

The supported vinyls are:
Serato (2nd Edition)
Traktor/Finalscratch (2nd Edition)
Since the code is based on flext it should compile on Mac OS 9/X, Windows and Linux (tested). The timecoder-code is taken from xwax. More info regarding the build process on the respective platforms is available at the flext-site. In general, you should be able to run build.sh/.bat <platform> <compiler> from within the source-code directory once the toolkits/headers are installed.
You need flext >= 0.4.1 in order to build this and of course the headers for either pure data or max/msp
Source & Binaries

src: vinylcontrol.tar.gz
pd-linux: vinylcontrol~.pd_linux
...more to come if someone sends me the binaries ... ;)
Usage:

vinylcontrol~ accepts two (optional) parameters:
1) vinyl-type (serato_2a, serato_2b, serato_cd, traktor_a, traktor_b)
2) smoothing: used to average pitch-values and the alive bang since the event generation is taking place on dsp-level.
The default values are serato_2a and 10.

The 3 outlets provide:
1) alive - bang is sent when the decoding starts/stops (ie. input is above a certain threshold and timecode is being tracked)
2) pitch - float that is 1 at 33 rpm in forward direction; negative values indicate backward-movement
3) relative position; the start is the first cue-point (first tracked timecode where the needle was dropped) and can be reset to the current timecode-position by sending a bang to the third inlet. The end position is the last sane timecode on the record. The position is calculated using (current_position-start_position)/(last_position-start_posit ion), thus giving a range between 0 and 1 between the end position and the relative start position and negative values for positions before the start position.

The 3 inlets are:
1) left input
2) right input (take care of the cabling from your turntable)
3) reset for the relative start position


The timecoder is used from xwax (http://www.xwax.co.uk), wrapping using flext was done by Niklas Klügel & Antoine Villeret.
You can’t perform that action at this time.
