The installer reports an system error when
This is most likely due to file corruption during the download
process. Unfortunately, this means that you will probably have download
the entire file again. Try using a different download site if possible.
You can also try downloading the .zip file on the download page
instead of the .exe file - the .zip file doesn't use the installer.
The application reports an error when starting
On Windows, this may be because it could not initialize DirectSound,
the technology used to mix the music. This may be because DirectX
is not correctly installed, or because some other application is
using the sound. Check Microsoft's web site at http://www.microsoft.com/directx
for help with DirectX.
I can't hear any music!
First, make sure your computer is set up for sound. Can you hear
sound from any other applications? On Windows, you can also check
the Multimedia control panel to see if the sound card is recognized.
Make sure your speakers are on, plugged in, and securely plugged
into the computer.
Next, check the level controls on the software. Each of the vertical
sliders should be most of the way up. The crossfader should be in
the middle or closer to the turntable you are trying to play.
Finally, make sure the sound file is valid. Either try another
file that you know is valid, or try the original sound file in another
The sound is choppy.
The record doesn't spin smoothly.
This probably means that your computer can't keep up with the software.
This may happen if your processor is too slow, you don't have enough
memory (RAM), or if your computer is already doing other things,
perhaps running too many other programs. This might also happen
if you don't have a good sound card or if you don't have the latest
DirectX drivers for your card.
If possible, try quitting other applications that you aren't using,
and downloading the latest drivers for your sound card from the
manufacturer's web site.
I can't open MP3 files!
If you are on a Macintosh, this may be because you don't have the
latest version of QuickTime. You need to have QuickTime 4 to play
MP3 files on the Mac. Also, it appears that QuickTime does not support
all variations of the MP3 format. Some users have reported problems
opening SoundJam MP3 files.
How do I record my mix?
For now, you have to connect the output of the sound card to a
tape deck or another computer. (see the wiring
page for a little more detail - if you're using the headphone
cue features, you should only connect right channel to the tape
deck.) If you connect the output to sound input of another computer,
you can either digitize the mix to a new sound file, or if you have
the software, recompress the mix and stream it to the net.
