Technical Information and Tips on Torq's Vinyl Control System
By Chad Carrier
When you first experience the thrill of controlling an MP3 file with external vinyl, some of you may feel that
it is nothing short of magic. In some ways, this is almost the truth because the system employed in Torq is very
complex and subject to numerous variables, all of which can have an impact on its performance. This docu-
ment will outline, in basic terms, the vinyl tracking system and its workings. Thorough knowledge of this in-
formation will help you get better performance from the system and also aid when troubleshooting issues.
An Introduction to Vinyl Tracking
Before starting, we must state that tracking vinyl is no small task, especially when the only mechanism avail-
able is a standard tonearm equipped with a standard stylus. There are many more mechanisms for reading the
rotation of an object that would yield better results but, as DJ's, this is what we're forced to use. This creates
some unique problems that have been solved by various companies in a number of similarly unique ways, all
with varying levels of reliability and accuracy.
We'll start now by explaining what kinds of information we need in order to make an MP3 (or similar digital
audio file) playback under the control of vinyl. There are three things the computer needs to know: The speed
of the record, its direction of rotation, and the position of the stylus on the record. The speed will tell the com-
puter how fast to play the audio file. The direction will determine if the file is played forwards or backwards.
The position will set the playback location within the file. With all three of these parameters being commu-
nicated to the computer at a high enough rate, the results are astounding. The audio file will react as if it's
pressed directly on the record. So how can a computer determine these three values by dragging a stylus across
some wax? The answer is sound.
How It Works
Each of Torq's Control Vinyl records are imprinted with special audio signals that the computer can listen to
in order to determine the speed, direction, and position of playback. In the case of Torq's tracking system, the
audio signal is comprised of two parts: The pilot tone and the position stamps. These two audio signals exist
simultaneously on the record, but in different frequency bands so they can be analyzed independently of one
another.
Torq uses the pilot tone to determine two of the three values: speed and direction. The pilot tone itself is ac-
tually very simple: It is a sine wave at a fixed frequency that plays throughout the entire duration of the re-
cord. If you've ever played with a record before, you'll know that changing the speed of the record causes the
pitch (key) of the music to change. For example, if you slow a record down, the pitch of the music will drop.

- The simplest method for searching is to type a keyword or keywords into the search field above the data base browser p.37
- Shift clicking a selected category will de select it p.37
- Searching the list p.37
- Search categories p.37
- Hold down the shift key and click a category name the category name will turn red p.37
- For example if you type the word love into the search field torq could return the following results p.37
- Click the database heading in the browser pane to select it p.37
- Click in the search field and type in your search term s terms can include an artist s name a song title bpm etc p.37
- As you can see the above search worked it found songs that contained the word love in any category however this may not be quite what you were looking for you may have actually wanted files with love in the song s name only to search for such titles you ll need to confine the scope of the search to the song cat egory only p.37
- As soon as you start typing torq will begin searching the database for the letters you have typed there is no need to hit the enter key on your keyboard p.37
- You can hold shift and click additional categories if you wish i e you can select song and album simul taneously p.37
- When you stop typing you ll have a list of all files that contain the search term in one of its fields p.37
- Torq will refine its search results and only show songs that contain your search term within the selected field p.37
- To search the list p.37
- To confine a search to a particular category p.37
- Type in the term you would like to filter out of the search p.38
- Torq will display only the songs that contain the information required in the search field while omitting the songs that fit the criteria of the ignore field p.38
- Torq offers another method for refining your searches by means of the ignore field here you ll enter terms that you want torq to omit from the search results the ignore command will only be applied to the currently selected categories explained above p.38
- To omit terms from the search results p.38
- Song preview p.38
- Once you have located and clicked on a song in the file list it can be previewed within the browser by press ing the preview button headphone icon on the left end of browser search bar pressing this button plays the song sending the audio signal through the pfl headphone cue to your headphones p.38
- Now only the songs with love in their titles are shown p.38
- Filter field p.38
- Click to put a cursor in the ignore field p.38
- Clear button p.38
- Again using the example above entering the term lover into the ignore field will return the following list p.38
- You ll see that as a result i d rather be your lover has been removed from the list p.38
- When you are done with your search and are ready to begin a new one press the clear button this will clear the search and ignore fields as well as deselect any categories that had been previously selected p.38
- Using our example above confining the search to the song category would yield the following results p.38
- Chapter 5 the decks p.39
- Four deck mode vs two deck mode p.40
- When the highlight deck assignment option is set to yes default on the gui page of the torq prefer ences the edge of currently targeted decks will be highlighted with a colored rectangle torq decks assigned to the left side of your controller are highlighted in green while decks assigned to the right side are high lighted in purple if a deck is highlighted in red it will be controlled by both sides of your hardware p.41
- The the table below lists key commands for assigning the decks to either side of an m audio xponent dj con trol surface however it is also important to remember that commands also bring the decks into focus when using your mouse and keyboard to control torq if you are using qualified third party hardware refer to the its documentation p.41
- The deck switch feature offers a set of key commands for assigning any deck to either side of your two deck hardware this lets you bring an assigned deck into focus as the target deck to be controlled by your hard ware this capability also extends to situations where you want or need to target and control any of the decks with a single hardware deck or with your computer keyboard and mouse p.41
