The creative mind behind App Sound is Matthias Sauer (Matt Sour). He is a sound- and music producer from Germany, located near Frankfurt. You can hear some of his presets in the synthesizer workstation YAMAHA MOTIF, in the groove boxes AN/DX200 and further YAMAHA instruments. Since the early 90ies he collaborates with Peter Krischker (Easy Sounds) and released with him many sound sets, among them the successful sets „Chill Xperience“, „Nature of Chill“, „Energy“ and „Ambient Soundscapes“ for YAMAHA MONTAGE series.

For KORG Japan he produced factory demo songs for the iPad apps KORG iPolysix and KORG Gadget and designed Performances for the KORG Wavestate as well. He created factory banks for popular software synths like PREDATOR and BLUE-2 by Rob Papen. For Unify by PluginGuru he created the libraries UniChill V1 and UniLoFi V1.5 together with John Lehmkuhl.

As a freelance journalist he regularly writes articles for the German press on music software and instruments: for example the Apple iPad workshop for the magazine tastenwelt, reviews and features for Beat magazine and the online magazine Bonedo.

Last but not least he is using his synthesizer presets for own music projects. The album „Wave Pirates“ is an ambient, electronic musical story of the deep sea, ancient boats, unexpected waves, storms and sunbaths. The creation of the whole album hides a special concept behind, the concept of one sound, specially created with the Korg Wavestate.
