If you are trying to play sounds in Beatcraft and it seems to cut off too soon or it may have some other strange behavior, try this:
In Beatcraft, click on the File menu and select Preferences. On the Playback tab, click on the Playback Device setting and choose the driver for your sound card. Do not choose "Default Sound Device" or any other option aside from your specific sound card"s driver.
If the problem persists, you should make sure that you have the latest drivers for your sound card. Download the latest drivers from your soundcard manufacturer"s website!
