You need to set up the audio driver in the program settings. If you select Direct Sound you should get playback for audio loops. If you also want playback for your MIDI keyboard and live recording you need to select ASIO. Music Maker offers Magix Low Latency as its standard ASIO driver. You need then click on the "Advanced..." button and activate your audio devices you want to use with the ASIO driver.
