Controller technology traditionally has referred to the Box that hangs on the piano where you insert your media. The problem is the only people that love those boxes are the people who design them. After all who wants a box hanging under their grand piano? QRS has seen the writing on the wall for some time now and completely migrated to an embedded web app system. While our competitors are selling CDs and Floppies or falsely relying on an internet connection to stream music, we have taken the bold step to include all of our content on board. No hiccups in playback, easy to navigate, easy to control all aspects of your player system -with a simple touch screen user interface. No reliance on a network connection to the outside world and instant purchases of your content. Don’t be fooled by competitors who also sell Apple products as an interface have the following issues we do not. They force the use of ITunes – so now a PC or Mac is required – your player music is mixed with your regular music – another thing to think about and plan around, the music has to be transmitted from the device (iPad or iPhone) to the piano – it’s not on the piano – so you have to be in range – on the same network … and the stream cannot be interrupted. Then of course you want to be able to control all aspects of your pianos performance – which is simply not doable with the built in media player; we mean all aspects not just a speaker and piano adjustment – from record to solenoid alignments. And last but not least we do not lock you into one brand of product – any Wi-Fi enabled device will control your piano. Really it’s that simple.
