DJ Tools RT1 is a Full featured Jingle Cart machine, with actually 20 available slot.
Every slot is preloaded with a factory sound, to demo the app.
The real difference with other sample machines is that you can load your OWN sample.
DJ Tools support MP3, MP4, WAV and WMA samples, up to any length.
For every sample you can see the time remaining till the end, with a timer and a progress bar. When 5 seconds are remaining during the playback, the corresponding sample start flashing, to alert that the track is reaching the end.

You can select for every sample the launch mode:
Shot -> Fire and Forget, Press again to stop the sample
Burst -> Every Button press restart the sample
Loop -> Loop continuously the sample until you press the button again

When you load your own samples, the configuration is automatically saved for the future use. Use the reset button to revert to factory settings.
