The Tactile12000 will mix the sound from the two turntables like
a real DJ mixer. Use the vertical level sliders
to independently control the volume of each turntable, or the rightmost
master volume slider to control the overall volume of the system.
Use the crossfader to mix proportionally
between the two turntables - sliding all the way to the left plays
only the left turntable, sliding all the way to the right plays
only the right turntable, and everything in between plays a relative
amount of each.
To preview the next track before playing it out to the crowd, use
the cueing feature. A DJ plays the
next record on his or her headphones (before sending it over the
speakers) in order to sync up the beats or just to start the song
in the right place.
Use the button with the headphones
icon to enable cueing. When it is turned on, cue channels are played
back in the left stereo channel, and the main output only plays
through the right channel. When the cue feature is turned off, the
main output plays back in both stereo channels. If you have two
sound cards on your PC, you can split the cue and main outputs into
two separate stereo outputs. Use the options dialog to set which
output goes to which card.
Press the 1 or the 2 button to select which turntable is being
cued up. You can put both turntables on cue and use the cue
crossfader to preview your mix. The cue channel also has
its own level slider. Cueing is split between the left and right
channels because most PCs only have a single stereo output. To use
the Tactile12000 as a real DJ mixing application, you will have
to direct only the right channel output to an amplifier and direct
the left channel to a pair of headphones. See the wiring
page for more information.
To get the beats of the songs to match, you may have to adjust
the speed of one of the records. Use the pitch
control to adjust the speed of the record by -8% to +8%.
Use the keyboard shortcuts for fine control of the pitch. To temporarily
speed up or slow down the record, use the tiny pitch
bend arrows near the middle of the pitch slider.
Also, you can use the mouse to stop or drag the record for a split
second to get the beats to align. To skip to an entirely different
part of the song, drag the tonearm
forwards or backwards.
The cue point buttons allow you to
mark a position in the song. Click the left button to mark the point,
and click the right button to return to the point.
You can "scratch" by clicking on the
record and dragging it back and forth. You'll notice that it's not
quite like real records and turntables - it's tough, and probably
even impossible, to get the range of sounds you can make with a
real turntable. The faster your computer is, the better it will
work. Real scratching is, and probably always should be, an analog

The Tactile12000 itself does not record your mix. You can plug
the output of your computer into your tape deck or stereo, or record
back to a hard disk. The Shareware
Music Machine lists a few software utilities to record audio
into a digital file.
You can also use other software to broadcast your mix back to the
internet. Check the list at the Shareware
