Kevin Hopkins

It is not an overstatement to say that Kevin literally knows all functions in MusicMaster no matter how hidden or complex they are. Kevin is your man when it comes to the question how to integrate MusicMaster into existing systems or when interfaces and realtime-database-synchronizations have to be programmed – due to his vast experience in network and automation technology. Last but not least, Kevin is your multilingual (German, English, Italian) voice in terms of tech support.
