Just in a nutshell: Make sure that your Music Maker is configured to use an ASIO driver to avoid latency related problems. You can change the driver model when you're in the main screen of Music Maker and press "P" on your computer's keyboard to bring up the program settings dialogue. Pick "ASIO driver" under the driver selection in the "Audio playback" section and choose a suitable ASIO driver from the drop-down list below. If your sound hardware doesn't provide ASIO drivers, you can opt for the generic "Magix Low Latency (2008)" driver. This will probably take care of the issue. Latencies beyond this might be related to insufficient system performance, though.
