Response to a similar question:https://www.bluemic.com/index.php?name=PNphpBB2&file=viewtopic&t=281&highlight=pianoI see the frequency response of the mic is 40 Hz - 18 kHz. It is important to note that the bottom A on the piano is approximately 27.5 Hz. Your bottom end might not be optimal in the piano's lowest notes. It sounds like a great idea though, for convenience you don't need a pre amp and AD converter. Also keep in mind you are limited by the length of your USB cable (I'm not sure about signal degradation in long runs of USB cables). For long runs of cable you may want to look at a more traditional mic with XLR connectors. It is still new technology, so maybe you would want to give it a try and tell us about it.
